In order to ensure wear resistance, high chromium wear plates generally need to be completely hardened, and the martensite structure should be obtained on the surface and the core. However, the surface and center of the high chromium wear plate are not simultaneously transformed. When quenching, the surface is cold, and the austenite to martensite transformation occurs first. When the surface martensite transformation is completed, the center begins. Martensitic transformation occurs. Since the martensite is larger than the bulk, the resulting tissue stress forms a tensile stress on the surface, and a compressive stress is formed in the core of the high chromium wear plate.
1.According to the design requirements to provide users with wear-resistant composite plate made of wear-resistant spare parts, such as cement machinery in the efficient powder wear-resistant parts, mill liner, mixer blade, fan blades.
2.Directly with the composite plate rolling round rolling into various types of wear-resistant pipeline, such as powder air delivery system, blast furnace slag system, spiral propeller blades and so on.
3.Directly to the user to provide surfacing board, by the user to their own materials, welding to complete the construction site, such as silos, chutes, large bucket and so on.
4.According to the size of the user parts wear area, to provide collar unit for on-site welding welding maintenance, to reduce the workload of the site welding, such as the work of the machine bucket, dredger dredger bucket.
