Problems solved by technology

[0002] Most of the lining parts of domestic coal, cement, ore and other material transportation equipment are made of ceramics, rubber, quartz, corundum, nylon, etc., which have poor wear resistance, impact resistance, and high temperature resistance. They are frequently replaced and difficult to install. Convenience affects production progress, so it is an urgent need for related industries to find a substitute material with high strength, wear resistance, impact resistance, high temperature resistance, easy installation and long service life
[0003] At present, the wear-resistant coated composite plate obtained by high-chromium cast iron wear-resistant coating on low-carbon steel plate has become a new product, but the development of this product is not yet mature, and the manufacturing method is complicated, so the performance of the product produced uneven

Abstract

The invention relates to a method for manufacturing a wearable coating composite board, which sequentially comprises the steps of base material clamping, coating technical parameter selection, coating, repair welding, cutting, edging, punching, removing burrs and shaping. The coating is formed by a sectional lamination process. The wearable coating composite board manufactured by the method has the characteristics of high rigidity, good wear resistance, light weight, corrosion resistance, high temperature resistance, impact resistance and the like, and is applied to various parts of a material transport system. The base material has a relatively good wear resistance which is eight times of that of the prior universally adopted wear-resistant material. The coating takes on transverse cracks so as to facilitate to release stress. Therefore, the wearable coating composite board can be bent, cut, welded and carried out with other processes. Various parts formed by process can be assembledand used on various different parts, have a relatively high corrosion resistance and a high-temperature red hardness, can bear a high temperature of over 500 DEG C, and have a moderate cost, a wide application range and an obvious comprehensive advantage.

Description

technical field [0001] The invention relates to a method for manufacturing a wear-resistant material, in particular to a method for manufacturing a wear-resistant coating composite plate that forms an alloy high-wear-resistant layer on the surface of ordinary carbon steel. Background technique [0002] Most of the lining parts of domestic coal, cement, ore and other material transportation equipment are made of ceramics, rubber, quartz, corundum, nylon, etc., which have poor wear resistance, impact resistance, and high temperature resistance. They are frequently replaced and difficult to install. Convenience affects production progress, so it is an urgent need for related industries to find a substitute material with high strength, wear resistance, impact resistance, high temperature resistance, easy installation and long service life. [0003] At present, the wear-resistant coated composite plate obtained by high-chromium cast iron wear-resistant coating on low-carbon steel...
