Wear solution materials are used to protect surfaces from wear and tear caused by friction, abrasion, and erosion. These materials can be applied to various surfaces, including machinery parts, industrial equipment, and pipelines. Some common wear solution materials include ceramics, polymers, and metals. Ceramics are known for their high resistance to wear and can withstand high temperatures. Polymers are lightweight and flexible, making them ideal for applications where weight is a concern. Metals are strong and durable, making them suitable for heavy-duty applications. Research is ongoing to develop new wear solution materials that are more efficient and cost-effective. Some of the latest developments include the use of nanotechnology to create wear-resistant coatings and the development of self-healing materials that can repair themselves when damaged. Overall, the use of wear solution materials is crucial in industries where equipment and machinery are subjected to harsh environments and frequent wear and tear.

Good sex price: The price of wear-resistant steel plate is higher than that of ordinary materials. However, considering the service life of products, maintenance costs, spare parts costs and downtime losses, its performance price ratio is much higher than that of ordinary steel plate and other materials. Is in the toughness, plasticity is very good ordinary low carbon steel or low alloy steel surface by surfacing method composite a certain thickness of high hardness, good wear resistance layer and made of sheet products.

Good connection performance: Strongplate wear-resisting steel plate base material is common Q235 steel plate, to ensure that the wear-resisting steel plate has toughness and plasticity, to provide strength of resistance to external forces, can take welding, plug welding, bolt connection and other ways to contact with other structures, strong connection, not easy to fall off, connection more than other materials.

FCAW Welding Wire is kind of Open Arc Welding Wire. According to the applications of surfacing alloy welding wire, the commonly used surfacing alloy welding wire can be divided into the following types. 1) Corrosion-resistant surfacing welding, also known as cladding surfacing welding, is a surfacing method in which a certain thickness and a corrosion-resistant alloy layer are deposited on the working surface to prevent the workpiece from corroding during operation. 2) Wear-resistant surfacing, Niobium Carbide Welding Wire can prevent the surface of the workpiece from being worn during the working process, to obtain an alloy layer with certain hardness and special properties on the surface of the workpiece, and to prolong the service life of the workpiece. 3) When surfacing the transition layer and repairing dissimilar materials by surfacing, ESAB Welding Wire prevents the adverse effect of the composition of the base metal on the chemical composition of the deposited metal, and to ensure the performance and quality of the welding head, first melt on the surface of the base metal (or the groove of the joint). Metallized transition layer (also called isolation layer). The process of depositing the transition layer is also called transition layer surfacing. Selection of surfacing alloy welding wire The correct selection of surfacing alloy welding wire can ensure that the surfacing layer exerts its good working performance, and can save alloy elements to the maximum extent and reduce the repair cost. When choosing a surfacing alloy welding wire, it is very important to meet the performance requirements of the use conditions and economic rationality. The workpiece material, batch, and the surfacing method and process to be used must also be considered. 1. Selection principle of surfacing alloy welding wire (1) To meet the performance requirements of the parts under the workpiece conditions, select the appropriate surfacing alloy welding wire according to the different requirements of the surfacing workpiece and working conditions. Understand the working conditions (temperature, medium, load, etc.) of the surfacing parts, and identify the type of damage during operation. Choose a surfacing alloy wire suitable for this damage type. For example, the chisel-type abrasive wear of the bucket teeth of the excavator is subjected to severe impact, and the surfacing alloy welding wire that can resist impact wear should be used. . (2) The selected surfacing material with good weldability should be easy to surfacing under field conditions and obtain a gold layer of surfacing alloy welding wire with good bonding with the matrix and no defects. Attention should be paid to the phase fusion between the surfacing alloy welding wire and the base metal. Especially in the repair of workpieces, the matrix is likely to be the original surfacing layer, and its chemical composition, microstructure and properties should be understood. When the carbon equivalent of the base metal is high, in order to prevent cracks in the process of surfacing repair, the process measures of preheating, heat preservation, slow cooling or post-weld heat treatment can be considered, and the process method of the transition layer in the surfacing can also be considered. (3) The economy of surfacing welding The selected surfacing alloy welding wire should be the one with the highest price among the various surfacing alloy welding wires with roughly the same performance. a kind of. The economic benefits after the surfacing parts are put into use should also be considered. Especially in the repair of major equipment, the cost of surfacing or processing may be higher, but because the repair time is shortened, the economic loss of equipment downtime is reduced, or the service life of components is extended, which will also bring huge social and economic benefits.

What is Flux-Cored Arc Welding? Flux-Cored Arc Welding was introduced in the 1950s. It is a process that is very closely related to Metal Inert Gas Welding. Both processes use similar equipment and continuous wire feeds, and both MIGW and FCAW use the same type of power supply. Flux-Cored Arc Welding typically uses a shielding gas similar to the MIGW process. However, Flux-Cored Arc Welding may also be performed without a shielding gas. Additionally, this type of welding is a much more productive process than MIG welding. In fact, FCAW is the most productive of the manual welding processes. How Flux-Cored Arc Welding Works During the Flux-Cored Arc Welding process, an electric arc is used to unite a continuous filler metal electrode with the base material. (Note: The MIG welding method uses a solid metal electrode, whereas, the FCAW process uses a hollow tubular electrode that is filled with flux.) The flux-filled metal wire electrode automatically feeds through the center of the gun using the same type of equipment that is used in Metal Inert Gas Welding. The use of the gas shield supplied by the gun protects the weld pool from oxidation during the welding process. The flux that is inside the electrode forms a slag (smelting refuse) that covers and protects the weld from the atmosphere. The shield that is provided by the flux allows the welding procedure to be more easily executed outdoors, even in the wind. The Suitability of Flux-Cored Arc Welding Flux-Cored Arc Welding is a very flexible welding method. This type of welding is suitable for all position welding with the proper filler metal and flux composition. The high deposition rates of FCAW contribute to the productivity of this process, which provides quality welds with excellent weld appearance. It is often used for welding thicker sections and has the ability to produce a fully-penetrated weld on both sides of half-inch plate in a single pass. The materials that work best with Flux-Cored Arc Welding are carbon steel, stainless steel, and low-alloy steels. Unfortunately, most non-ferrous metals, including aluminum, cannot be welded using the FCAW method. Because of its high welding speed and the ability to be performed outdoors, even in windy conditions, Flux-Cored Arc Welding is frequently used in the construction industry.

Introduction on the influence of various alloying elements in the welding core on welding 1) Carbon (C) Carbon is the main alloying element in steel. When the carbon content increases, the strength and hardness of the steel increase significantly, while the plasticity decreases. In the welding process, carbon plays a certain role in deoxidation, and it chemically reacts with oxygen under the high temperature of the arc to generate carbon monoxide and carbon dioxide gas, which removes the air around the arc area and the molten pool to prevent oxygen and nitrogen in the air. Adverse effects on the molten pool, reducing the oxygen and nitrogen content in the weld metal. If the carbon content is too high, the reduction effect will be severe, which will cause large splashes and pores. Considering the effect of carbon on the hardenability of steel and its increased crack susceptibility, the carbon content of low carbon steel cores is generally 0.1%. 2) Manganese (Mn) Manganese is a good alloying agent in steel, and its strength and toughness will increase with the increase of manganese content. In the welding process, manganese is also a good deoxidizer, which can reduce the oxygen content in the weld. Manganese and sulfur combine to form manganese sulfide floating in the slag, thereby reducing the tendency of hot cracks in the weld. Therefore, the manganese content of the general carbon structural steel welding core is 0.30% to 0.55%, and the manganese content of some special-purpose steel wires is as high as 1.70% to 2.10%. 3) Silicon (Si) silicon is also a good alloying agent. Adding an appropriate amount of silicon to the steel can improve the yield strength, elasticity and acid resistance of the steel; if the content is too high, the plasticity and toughness will be reduced. In the welding process, silicon also has good deoxidation ability and forms silicon dioxide with oxygen, but it will increase the viscosity of the slag and easily promote the formation of non-metallic inclusions. 4) Chromium (Cr) Chromium can improve the hardness, wear resistance and corrosion resistance of steel. For mild steel, chromium is an incidental impurity. The main metallurgical feature of chromium is that it is prone to rapid oxidation to form the refractory oxide chromium trioxide (Cr2O3), which increases the possibility of weld metal inclusions. After the chromium trioxide transitions to the slag, the viscosity of the slag can be increased and the fluidity can be reduced. 5) Nickel (Ni) Nickel has a relatively significant effect on the toughness of steel. Generally, when the low temperature impact value is required to be high, some nickel is appropriately added. 6) Sulfur (S) Sulfur is a harmful impurity. With the increase of sulfur content, it will increase the hot crack tendency of the weld, so the content of sulfur in the welding core should not be greater than 0.04%. When welding important structures, the sulfur content shall not exceed 0.03%. 7) Phosphorus (P)

Processing of Hard Surfacing Abrasion Resistant Steel Plate The surfacing Wear Plate can be welded into various structural parts or components through the welding of the base layer steel plate. A plasma cutting gun is used to punch holes in Wear-resistant Composite Steel Plates, and bolts are used to fix them. It is fixed on the protected equipment for easy maintenance and replacement. Welding wear-resistant Chromium Carbide Steel Plates have high hardness and require plasma cutting. According to the different size and shape requirements of users, we can provide wear-resistant plates of corresponding sizes and shapes. Users can also purchase the entire wear-resistant plate and cut it by themselves. According to the hardness and thickness of different wear-resistant steel plates, the minimum bending diameter is different. Usually, the minimum bending diameter is ≥350mm, and it can be made into flat plate, arc plate, cone plate and cylinder. During reel processing, the bending direction should be consistent with the direction of the weld bead as much as possible, especially for small diameter bending, which needs to be bent according to the requirements of the supplier! Features of surfacing wear plate: 1. Improve economic efficiency: improve equipment operation rate, reduce production downtime and maintenance loss, increase production capacity and increase efficiency. 2. Reduce production costs: reduce the number of workers, long-term benefits from one investment, and high cost performance. 3. Improve the production environment: block running, dripping and leaking, avoid environmental pollution, and is conducive to the cleanliness of the factory environment. 4. Protect the health of workers: reduce the probability of workers working in harsh environments, reduce high-altitude and narrow space operations, and reduce work intensity. 5. Significant social benefits: reduce the waste of cast alloy plates and ordinary carbon plates, save the amount of precious alloys, and scientific and technological progress brings comprehensive social benefits. Wear-resistant plate surfacing equipment is a new type of modern composite wear-resistant steel plate material, which has been popularized and used in industrialized countries since the 1960s. With the development of science and technology in our country and the needs of market economy development, the special properties and practical economic value of wear-resistant surfacing clad steel plates are gradually being managed by some large industrial and mining enterprises with advanced consciousness. It has been recognized and used by the users, and has created considerable economic benefits for the enterprise.

In modern large-scale industrial production, the problem of failure of mechanical components caused by wear is very serious, especially with the development of chemical, energy, transportation and other industries, in the fields of modern industry, cement, and smelting, the problem of failure caused by wear and tear is very serious. more serious. With the development of surface engineering technology, the promotion and use of large-area composite plate surfacing technology, the United States, Canada, Australia, the United Kingdom, etc. have widely used this technology in industrial production, while my country has only begun to apply it on a large scale in recent years. HP Plate is a new type of composite steel plate made of new open arc surfacing flux-cored welding wire on ordinary Q235 steel plate. The advantages of composite steel plate High wear resistantance In the chemical composition of the layer, the carbon content is 3%~5%, the chromium content is as high as 20%~40%, the volume fraction of carbides in the metallographic structure is more than 50%, the macro hardness is HRC55~65, and the microscopic carbides are microscopic. The hardness is HV1400-1800, which is higher than the microhardness HV800~1200 of quartz in sand. The energy of the composite steel plate is 5~6 times that of heat-treated steel, 5 times that of stainless steel, 5~6 times that of high manganese steel, and 11 times that of Q345 (16Mn) (experimental data of abrasive wear at room temperature). When surfacing the plate, the process method is used to control the growth direction of the carbide, so that the growth direction of the carbide is perpendicular to the flow direction of the abrasive, even compared with the casting alloy of the same composition and hardness, the energy can be increased by more than 1.3 times, which is far It is much higher than the layer prepared by spray welding and thermal spraying, and is suitable for dust and abrasive wear under the working conditions of dust concentration not greater than 3kg/m³ and airflow speed not greater than 25m/s. Good impact resistance The substrate of the composite steel plate is a ductile material such as low carbon steel or low alloy steel, which reflects the superiority of bimetal. The layer resists the wear of the abrasive medium, and the base plate bears the load of the medium, so it has good impact resistance and can withstand the impact and wear under working conditions such as high drop hoppers in the material conveying system. Easy processing performance The composite steel plate can be cut, leveled, holed, bent and curled into shapes such as flat plates, arc plates, cone plates, and cylinders. The cut composite panels can be made into various forms of engineering structural parts or components by tailor welding. Composite panels can also be hot-pressed into complex shapes with molds. The composite steel plate can be fixed on the equipment by means of bolts or welding, which is convenient for replacement and maintenance. Good cost performance Although the manufacturing cost of clad steel plate is high, it can prolong the service life of components, so maintenance costs and downtime losses are greatly reduced. High equipment utilization means high production efficiency and enterprise economic benefits, and its cost performance is higher than that of ordinary materials. About 2 to 4 times. As the material handling volume increases, the wear becomes more serious, and the impact on the operation rate is greater, and the use of suitable clad steel plates will produce more obvious economic benefits.

Surfacing wear-resistant pipe is a new type of wear-resistant pipe. It uses steel pipe as the base, and the wear-resistant layer and the base form a solid metallurgical combination of super wear-resistant alloy materials. The inner wall is made of surfacing welding, which is suitable for the production of wear-resistant pipes with small diameters. The surfacing wear-resistant pipe can be divided into two types according to the processing method, one is the inner wall surfacing steel pipe, and the other is the coiled wear-resistant composite steel pipe. The difference between them is that the rolled wear-resistant composite steel pipe can only be deformed and rolled into a tube when it is strongly squeezed by the rolling machine, so the adhesion between the wear-resistant layer and the substrate will be seriously damaged, resulting in falling off and falling blocks. The impact resistance and vibration resistance performance will be greatly reduced. Due to the plasticity of the substrate and the brittleness of the wear-resistant layer, and all the rolled tubes have joints, it is inevitable that the ovality error will be large. The surfacing wear-resistant straight pipe produced according to the drawings provided by the customer is used for coal feeding pipe, material conveying pipe, etc., with high machining accuracy, high wear resistance, high impact resistance, convenient welding performance, high performance Although the surface cost of using wear-resistant surfacing pipes increases, considering the service life of the parts, maintenance costs, downtime losses, etc., the cost performance is about 2 to 4 times higher than that of ordinary materials. The chromium carbide surfacing wear-resistant pipe not only has excellent wear resistance, high temperature resistance and impact resistance, but also has good toughness, excellent mechanical and thermal shock resistance, good weldability and easy installation. It is especially suitable for wear and impact in alpine and high temperature environment. Such as electric power, metallurgy, coal, mining, cement and other industries material transportation. Compared with other wear-resistant pipes, this product has high cost performance, long service life and low investment cost.

Our company independently developed a new type of wear-resistant pipe with domestic advanced level. It is a super wear-resistant alloy material with steel pipe as the base, and the wear-resistant layer and the base form a solid metallurgical combination. It is fully automatic through the inner wall numerical control. The surfacing welding machine is directly surfacing on the inner wall of the steel pipe, which is suitable for wear-resistant pipes with small diameters; our company can produce all the inner diameters above 80mm. So far, the wear-resistant composite steel pipe can be divided into two types, one is the inner wall surfacing steel pipe, and the other is the rolled wear-resistant composite steel pipe. The difference between them is that the rolled wear-resistant composite steel pipe can only be deformed and rolled into a tube when it is strongly squeezed by the rolling machine, so the adhesion between the wear-resistant layer and the base plate will be seriously damaged, resulting in falling off and falling blocks. The impact resistance and vibration resistance performance will be greatly reduced. Due to the plasticity of the substrate and the brittleness of the wear-resistant layer, and all the rolled tubes have joints, it is inevitable that the ovality error will be large.

According to our experience, the first level of product quality control is the selection and control of raw materials. As far as the situation in the industry is concerned, large-scale enterprises and famous brand enterprises generally use the products of large domestic steel mills. However, small enterprises and some enterprises use surrounding steel mills and even steel strip products of unknown origin. We hereby suggest and also call on the wear-resistant wire industry to use products from large steel mills as much as possible. HP Welding wire has been using Baosteel's special steel strip for flux-cored welding wire. The raw material of the steel strip of large steel mills has stable chemical composition, especially the control of impurity content is relatively stable, and the surface of the steel strip has no defects such as burrs. The steel strip with stable quality and excellent quality can ensure the stability of the overall chemical composition of the welding wire, realize the original design requirements, and also ensure that the wire can be discharged smoothly when the user uses it, and it is not easy to cause problems such as wire blocking and wire jamming. Although Baosteel products and distributors will provide the chemical composition quality inspection documents of each batch of steel strip products. However, we still recommend that wear-resistant welding wire companies check again when they are put into storage. Although the results of the self-test are basically in line with the report provided by the manufacturer. However, we have also found that the results are quite different through self-inspection. After the round-robin investigation, we finally found that there was an error in the upstream dealer's entry and exit links. If the inspection control is not set in the process of raw material storage, then this batch of steel strips will be processed into finished welding wire, and the problem will not be found until the inspection and control of the finished product, and the direct loss to the enterprise will be more serious. Compared with the quality of steel strips, the quality control of alloy powder raw materials is a more difficult and complicated task. Wear-resistant welding wire uses a large number of alloy powders, a large number of specifications, and a large number of technical parameter requirements. As for suppliers, so far, there is no company that can supply all alloy powders at the same time. In addition, due to scale factors, as well as quality awareness, the quality control of most alloy powder manufacturers falls far short of the needs of wear-resistant wire manufacturers. Solving the problem of alloy powder quality control is a long and difficult task. Our lessons and experience are that, first of all, we must strictly control the warehousing inspection, and we must carry out the warehousing inspection for each batch. This is the most effective and powerful measure. Warehousing inspection work, start with the main element inspection, and then carry out the impurity inspection work after the main element inspection is proficient. Secondly, the choice of suppliers should be expanded from domestic to overseas. So far, more than 50% of our alloy powder raw materials are imported products. Here, for some alloy powders, the procurement cost is lower than that of domestic suppliers. Even if some alloy powders are slightly higher than domestic suppliers in terms of procurement cost, they are superior to domestically supplied products in terms of product purity, particle size, impurity content, loose packing ratio and other technical perspectives. Value, value for money range. According to our experience, customers not only pay attention to the product performance indicators such as hardness and composition of wear-resistant welding wire, but also pay more attention to the entire production process of wear-resistant welding wire, especially the quality control work. In terms of raw materials, good quality control, practical implementation of raw material storage testing, and selection of raw materials from well-known manufacturers will win the trust and goodwill of customers.

NM400 wear-resistant plate needs to be coated before use, this is mainly to protect it from wind and rain during use and prolong its service life. When coating, the surface of the wear-resistant plate needs to be cleaned, so that the coating is more convenient. So we have to do it on a case-by-case basis. What is the specific coating process? Let's see the detailed introduction recommended. The coating quality of NM400 wear-resistant plate is higher than that of spiral submerged arc welded pipe. The cost of investing in a large unit of production units, workflow, and steel pipe processing is relatively high. Relatively low yield because no repair welding, no head tube allowed. Electric resistance welded steel pipe directly, therefore, the price is higher than the spiral submerged arc welded steel pipe about the total cost from the construction of the pipeline plate, without increasing. Welded pipe seamless mainly includes two aspects of connotation, it is seamless geometry, mechanical method, multi-purpose blowing heat, eliminating internal and external weld hair, followed by physical seamless, application. Such as heat treatment process, welding, heat-affected zone microstructure and mechanical properties of NM400 wear-resistant plate are based and consistent. Spills are unimportant welding defects, but there are more than 3 mm of super base metal surface unevenness should be ground with a grinding wheel. Spill because when the electrode melts rapidly, the molten metal fluid solidifies along the pool of parent metal. Spills are often formed when the arc welding operation is currently selected too large, or when the draw is too long. Can easily occur in vertical or reverse soldering. There may be a phenomenon that the parent material overflows and penetrates insufficiently. Supervision finds overflow, pay attention to check that there is no seepage defect behind the overflow groove

Open arc surfacing flux cored wire has main service areas as following- Cement industry: roller press extrusion roller, vertical grinding roller and grinding disc, fan blade, lining plate, chute, funnel lining plate, crusher hammer head and hammer disc, excavator bucket teeth, jaw plate, shaft kiln tower grate teeth , mixer blades, etc. Electric power industry: water turbines, steam turbines, valves, pulverizing roller sleeves and grinding discs, chute liners, crusher hammer heads and liners, pulverizer rollers and liners, exhaust fan blades, etc. Iron and steel enterprises: roller crushers, various rollers, blast furnace charge clocks and distribution chutes, single-toothed rollers, grate plates, sinter crushers, fan impellers, propeller tooth plates, funnels, recovery buckets, wear plates, guides Bit plates, high temperature die cutting tools, etc. Mining (dredging industry): chutes, hopper liners, brick machine reamers, fan blade liners, bulldozer buckets, ductile machine liners, bucket excavator buckets, bucket teeth, etc. Rubber industry: tire crusher cutter, rubber mixer, etc. Petrochemical (automobile industry): high temperature and high pressure pipelines, boiler pipelines, high pressure vessels, valves, petroleum refining equipment, petroleum cracking equipment, synthetic chemical machinery, cylinders, automobile bodies and parts, etc. Product name: Wear-resistant open-arc surfacing flux-cored wire Product specification: 1.6mm, 2.8mm, 3.2mm, 4.0mm (welding wire diameter can be customized) Product packaging: 250kg/Drum or 15kg/Spool

Wear-resistant composite plate has developed rapidly in recent years, but wear-resistant composite plate will also suffer some damage in some ordinary operations, so how should we deal with these damages? First of all, where there is dust, the dust will continue to fall on the steel plate. At this time, we can use water or alkaline solution for sanitation. In addition, the floating iron powder or the iron embedded in the iron will rust, and the iron attached to the wear-resistant composite plate will also rust the steel plate, so these irons must be disposed of, we can use carbon steel wire brushes. It can also be treated with ordinary carbon steel and so on. The third is scratches. These scratches are usually left during the process of manufacturing. Some stubborn iron scratches need to be picked up with a polishing machine dedicated to wear-resistant composite plates. The fourth is rust spots. If you see that the steel plate is rusted before processing, it means that the surface of the wear-resistant composite plate has been seriously polluted, and it should be cleaned up in time. The fifth is the scar. The scar is formed during the welding process, usually because the welder has a rough surface when the argon arc welding is performed, and there may be defects, which damage the protective film of the steel plate and leave the risk of corrosion. Welding spatter is likely to occur during welding, which is likely to leave some spatters on the wear-resistant composite plate, so these spatters should be picked up after welding. Do not cause damage to the surface of the steel plate. There will also be some welding defects during welding, such as undercuts, lack of penetration, etc. Such defects will also cause some damage to the wear-resistant composite plate. To solve this problem, either re-welding is carried out, or welding is performed. Repair the damaged area after grinding. The sixth is grease and oil, as well as adhesives. These things will always adhere to the surface of the steel plate and become the corrosion source of the wear-resistant composite plate. When cleaning, use a clean brush and water for scrubbing, and alkaline cleaners are also available.

The surfacing composite wear-resistant plate is based on mild steel plate, and a layer of chromium carbide is surfacing on the surface to make the steel plate have higher strength. Therefore, the quality of the surfacing wear-resistant plate is mainly determined by the welding wire and the surfacing process. There are many detailed classifications of wear-resistant welding wires. First, it can be divided into single-layer welding wire, double-layer welding wire and multi-layer welding wire. From the use category, it can be divided into various repair welding wires and gas shielded welding wires. High-quality welding wire has smooth wire feeding, stable arc and uniform diameter. The spatter of the welding wire is small, the smoke is small, and the deposition efficiency is high. For high-quality welding wire, each package of welding wire is basically a whole welding wire without seams. The welding wire with the above characteristics is a high-quality welding wire. Welding wire is classified according to diameter. There are mainly several specifications, 1.2mm, 1.6mm, 2.4mm, 2.8mm and 3.2mm. Different specifications of welding wire have different hardness. The hardness of high-quality welding wire must reach HRC55 or more. The content of carbon and chromium determines the hardness of the welding wire. The carbon content of the basic welding wire is about 3.0-5.0, and the chromium content is between 15-40. After the high-quality welding wire is surfacing, the butt welding layer on the surface should have good impact resistance and not easily fall off. Welding wire can also be subdivided in more detail according to different industries. For example, in some manufacturers, the welding wire can be subdivided into cement vertical grinding surfacing welding wire, roll surfacing welding wire, squeeze roller surfacing welding wire, star wheel for different use machines. Repair welding wire and other specific classifications. The gas shielded welding wire can also be subdivided into impact-resistant welding wire, high-temperature welding wire, gas-shielded repair welding wire, and welding wire containing various special elements. In the production of surfacing wear plates, the welding plate platform is very important. The current advanced welding plate platforms are all fully automatic multi-head platforms. The multi-head platforms have higher welding efficiency than single-head platforms. The wear-resistant plate of surfacing welding is not easy to fall off, and the flat plate is bent. Moreover, the new welding plate platform has a high level of automation, which can control the start and stop, height of each welding torch, and can realize the function of continuous welding at interruption points. The welded bimetal composite wear-resistant plate should have uniform surface hardness, flat surface and fine cracks. In addition, the surfacing process can not only produce bimetal wear-resistant plates, but also can use wear-resistant pipe surfacing equipment to perform surfacing in the steel pipe to produce surfacing wear-resistant plates.

Product description The bimetal surfacing pipe is mainly manufactured by surfacing welding technology. The mechanical part of the surfacing pipe manufacturing equipment is designed reasonably, and the electrical uses the key surface to input data, which can realize the free connection with other equipment and the welding machine; the walking speed can be adjusted at any time according to needs. The welding bead can be automatically arranged and continuous surfacing. The wire feeding adopts automatic wire feeding. The swing speed and width of the welding gun can be set by themselves; the height of the welding gun during the welding process adopts an independent automatic tracking system to improve the overall work efficiency. Product Usage Metallurgy, power industry transportation of coal powder, ash, mud, lime gypsum slurry, etc. require a large amount of metal pipelines every year. Mine: Mine filling, ore concentrate and tailings transportation cause serious wear on pipelines. The service life of ore powder transportation pipelines used in the past, such as Panzhihua and Daye Mine, is less than one year. Changing to this pipe can increase the service life by about 5 times. Coal: Coal preparation and long-distance pipeline coal transportation generally adopt wet transportation, and the transportation pipe is required to be corrosion-resistant. The pipe can be used as a long-life transportation pipe with considerable economic benefits. Craftsmanship The bimetallic surfacing pipe produced by HP has undergone a series of processing and transformation, and its products are of very good quality. The problem often encountered in surfacing welding is cracking. The methods to prevent cracking are mainly preheating before welding and slow cooling after welding. Surfacing effect. For example, the hardness and heat resistance of the surfacing layer are related to the welding current and arc length. If the current is large and the arc is long, the alloy elements are easy to burn, and the current is small and the arc is short, which is beneficial to the transition of alloy elements. Some surfacing metals can use different heat treatment methods with different hardness. The hardness and chemical composition of the surfacing metal generally refers to the surfacing metal of more than three layers.

The side baffle of the roller press can prevent the leakage of the roller face and improve the extrusion effect, but it is also one of the main wearing parts of the roller press. Therefore, it is of great significance to master its wear mechanism and take corresponding anti-wear measures to improve the extrusion effect, improve the production quality of the mill and prolong the service life of the side baffle. Roller press due to its well-known energy-saving effect, so, more and more widely used, but there is also the problem of fast wear in the process of use, the main wearing parts are roller surface and side baffle, especially the side baffle, when the roller press word grain or pattern wear is very small, the side baffle has worn.From the actual use of the situation, in the early use, the service life of the side baffle is only about a week, the long life is also a month. It is very important to improve the wear resistance of the side baffle. The general anti-wear measures are wear-resisting steel plate, wear-resisting casting, hard alloy and composite wear-resisting steel plate.Yangzhou Yuanyu Wear-resisting Mechanical and Electrical Co., Ltd. through the use of unit practice proved that the hardness of the composite wear-resisting steel plate is as high as HRC60 or more, the use of composite wear-resisting steel plate material is the best effect, than the original use of wear-resisting casting service life increased by more than 3 times, and the price and side baffle combination prices are not much different.The wear of the side baffle is larger, and the normal is that the wear-resisting layer should be repaired with wear-resisting electrode or directly replace the new side baffle!

What are the differences between flux-cored electrode wire and solid electrode wire? Is one type of electrode better than the other for welding? What are the advantages and disadvantages of each type of wire? Flux-Cored Wire Electrodes There are two types of flux-cored wire electrodes: gas-shielded and self-shielded. As its name implies, the gas-shielded type of flux-cored wire requires an external shielding gas. The self-shielded variety does not. The flux coating on gas shielded flux-cored wires solidifies faster than the molten weld material. Consequently, a sort of shelf is created which holds the molten pool when welding overhead or vertically up. Gas-shielded flux wires work well when welding thicker metals. They also work well for welding out-of-position applications. Slag removal is easy with this type of wire. Self-shielding flux-cored wires do not require an external shielding gas. With this type of electrode, the weld pool is protected as gas is generated when the flux from the wire is burned. Because the self-shielding wire produces its own protective shield and doesn`t require an external gas tank, it is more easily carried about. Advantages of Flux-Cored Wire Electrodes There are several advantages of using flux-cored wire electrodes. These advantages include but are not limited to: They allow for a high deposition rate. They work well outdoors and in windy conditions. With the right filler materials, these electrodes can make FCAW an [all-position" process. Typically, flux-cored wires create clean, strong welds. Disadvantages of Flux-Cored Wire Electrodes There are concerns with any type of welding method. Regardless of the process and type of electrode used, there is the possibility of creating an incomplete fusion between the base metals. Slag inclusion or cracks in the welds may also result. Additional problems that may arise when using flux-cored electrode wires include: A melted contact tip may occur if the electrode contacts the base metal and fuses the two together. If gases do not escape the welded area before the metal hardens, the weld may develop holes and become porous. Solid Wire Electrodes Solid wire electrodes are used in Metal Inert Gas Welding. Such electrodes require a shielding gas, which is delivered from a pressurized gas bottle. The shielding gas protects the molten weld pool from atmospheric contaminants. Solid wire electrodes are often made of mild steel which is plated with copper to prevent oxidation and to aid in electrical conductivity. The copper plating also helps to increase the life of the welding contact tip. Solid wires are the best choice when working on thin materials, such as sheet metal. They should produce nice, clean welds. Solid wire electrodes do not work well in wind. Exposing the shielding gas to the wind can compromise the integrity of the weld. Which Wire is the Best Choice? When comparing the flux-cored wires to the solid wires, it would be wise to note that the best choice is dependent upon the welding job and location. Both types of wires can produce sound welds with good weld bead appearances, when done correctly. For thicker metals and outdoor jobs, the flux-cored wire electrodes work best. For thinner metals and jobs performed out of the wind, solid wire electrodes can work quite well. Solid wire electrodes used in MIG welding are not as portable as flux-cored wires. This is due to the necessity of a shielding gas in MIGW. Both solid wire electrodes and flux-cored wire electrodes are relatively easy to use. However, flux-cored wire electrodes are more costly.
