Bisetallic compound layer wear-resistant steel plate is a plate product specially used for large area of wear condition. It is made of ordinary low carbon steel or low alloy steel surface by surfacing method of a certain thickness layer with high hardness and excellent wear resistance.
Bimetal composite wear-resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the anti-wear layer generally accounts for 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the comprehensive performance such as strength, toughness and plasticity, and the wear-resistant layer provides the wear-resistance to meet the requirements of the specified working conditions.
Wear-resistant steel plate alloy wear-resistant layer and matrix is metallurgical combination. Through the special equipment, the use of automatic welding process, the high hardness self-protection alloy welding wire is evenly welded on the substrate, composite layer one to two layers to multiple layers, the composite process due to different alloy shrinkage ratio, uniform transverse crack, which is the remarkable characteristic of 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 above HV1700-2000, and the surface hardness can reach HRc 58-62. Alloy carbide has strong stability at high temperature, maintain high hardness, but also has good antioxidant properties, within 500℃ completely normal use.
Wear-resistant steel plate has a 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.
