Performance advantages of composite wear-resistant plates
Composite wear-resistant plates have the characteristics of high wear resistance, impact resistance, and easy processing. They can be connected to other structural components through welding, plug welding, bolt connection, and other methods. They are widely used in industries such as ports, docks, metallurgy, cement, coal, power, mining, steel, building materials, bricks, and tiles. Compared with other wear-resistant materials, they have a higher cost-effectiveness and have been increasingly favored by manufacturers and customers.
1. Has high wear resistance
(1) The carbon content in the alloy layer of the bimetallic wear-resistant plate is 4.5-5.5%, with a chromium content of over 30%. The volume fraction of Cr7C3 carbides in the wear-resistant layer reaches 50-70%, with a macroscopic hardness of HRC60-64 and a microscopic hardness of HV1400-1800. The distribution direction of carbides is perpendicular to the wear direction, greatly enhancing the service life of the wear-resistant layer.
(2) And ceramic wear-resistant particles can be added according to actual working conditions and customer requirements, with small particle size to enhance the overall hardness of the matrix and improve the material's resistance to abrasive wear.
(3) The wear resistance of the independently developed and designed bimetallic wear-resistant plate is 15-20 times that of ordinary carbon steel; 7-8 times higher than high manganese steel; 6 times that of stainless steel; Eight times that of alloy cast steel.
2. Has good high-strength impact resistance
The substrate of the composite wear-resistant plate is made of ductile materials such as low-carbon steel, low alloy steel, or stainless steel, which highlights the superiority of bimetallic materials. The wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, thus having good impact resistance.
3. Good reprocessing ability
Composite wear-resistant plates can be cut, leveled, punched, bent, and curled, and can be made into flat plates, arc plates, cone plates, and cylinders. The cut composite wear-resistant plate can be welded into various engineering structural components or components. Composite wear-resistant plates can also be heated and pressed into complex shapes using molds. Composite wear-resistant plates can be fixed to equipment with bolts or welding, making replacement and maintenance convenient.
4. High cost-effectiveness
Although the manufacturing cost of composite wear-resistant plates is higher than that of ordinary steel or wear-resistant materials, their service life is several times longer, which greatly reduces maintenance costs and downtime losses. Their price performance is about 2-4 times higher than that of ordinary materials. The larger the material processing capacity and the more severe the equipment wear in factories and mines, the more obvious the economic effect of using wear-resistant composite steel plates.
