Stainless Steel Surfacing Wear-resistant Lining
Overlay-welded wear-resistant lining plate refers to the wear-resistant lining plate made of high hardness and high alloy wear-resistant welding wire directly overwelded on A3 steel plate. Compared with the traditional wear-resistant lining plate, the traditional wear-resistant lining plate is made by steel mills after dissolution, rolling, and this new type of overpile welding wear-resistant lining plate production after overwelding loading by cutting, coil deformation, drilling and welding production process processing into various wear-resistant lining plate, such as conveyor lining plate, coal feeder bottom plate / cyclone separator inverted cone and lining plate, wear-resistant blade, wear-resistant life can be more than 15 times higher than the ordinary steel plate.
Wear-resistant steel plate alloy wear-resistant layer and matrix is metallurgical combination. Through the automatic welding process. The number of composite layers is one to two layers or even multiple layers. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a remarkable characteristic of the wear-resistant steel plate. The wear-resistant layer is mainly composed of chromium alloy, and manganese, molybdenum, niobium, nickel and other alloys are also added. The carbide in the metallographic tissue is distributed in the fiber shape, and the fiber direction is perpendicular to the surface. The carbide microhardness can reach more than HV1700-2000, and the surface hardness can reach HRc 58-62. Alloy carbide has a strong stability at high temperature, maintain a high hardness, but also has a good antioxidant properties, within 500℃ completely normal use. Wear-resistant steel plate has high wear resistance and good impact performance, can cutting, bending, welding, welding, welding, plug welding, bolt connection with other structure, in the process of the maintenance of time, convenient, widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and other industries, compared with other materials, has a high cost performance, has been favored by more and more industries and manufacturers.
The main materials of overwelded wear-resistant lining plates include the following:
High chromium rewelded wear resistant plate: this material is made of high hardness, high alloy wear resistant welding wire directly overwelded on A3 steel plate, which has excellent wear resistance.
Chromium carbide high manganese high chromium surfacing wear resistance plate: this material uses chromium carbide alloy in the stack welding process, improve the wear resistance and hardness.
bimetallic composite wear plate: this material combines the advantages of different materials such as metal and ceramics, with high hardness and good wear resistance.
Overwelding wear resistance plate is a kind of special steel plate made by welding wear resistance layer on the surface of ordinary steel plate. This wear resistance layer is usually composed of alloy materials with high hardness and high wear resistance, such as tungsten carbide, chromium and molybdenum alloy, etc. Its main purpose is to significantly enhance the wear resistance of the steel plate surface, prolong the service life, and is suitable for the working environment that needs to withstand strong abrasion, such as mining equipment, cement mixer, conveyor belt, excavator bucket, etc
