Abstract

The invention relates to a high abrasion resistance dual-metal composite wear-resisting plate. The composite wear-resisting plate comprises a low-carbon steel plate or a low-carbon alloy steel plate, and a wear-resisting alloy layer is soldered on the low-carbon steel plate or low-carbon alloy steel plate. The composite wear-resisting plate is characterized in that the wear-resisting alloy layer comprises the following components in percentage by mass: 0.35-0.55 percent of C, 2-2.4 percent of Si, 2.7-3.2 percent of Mn, 11-12.5 percent of Cr, 2.5-2.9 percent of Mo, 0.7-1.8 percent of V, 2.2-3.6 percent of W, 0.7-1.1 percent of B, and the balance of iron. The high abrasion resistance dual-metal composite wear-resisting plate has the advantage that a flat and smooth surface of the wear-resisting plate can be guaranteed.

Description

technical field [0001] This patent belongs to the technical field of wear-resistant materials, in particular to a high-wear-resistant bimetal composite wear-resistant plate. Background technique [0002] In the surface forming of bimetallic clad wear-resistant steel plate, the smoothness of the surface is of great significance. The flat and smooth surface makes all parts of the wear-resistant plate have uniform wear resistance and uniform service life, and can reduce the friction coefficient and the resistance when materials pass through, which is beneficial to improve the service life. If the wear-resistant surface is rough and uneven, the resistance when the material passes through is increased, and the wear is intensified; the recessed parts are easy to fail early, resulting in a reduction in the overall service life of the wear-resistant plate. In addition, the flat and smooth surface means that the weight of wear-resistant plates of the same size is the same. For compo...
