Metallurgical bonding and composition requirements of wear-resistant steel plates
Oct 22, 2018

The wear-resistant steel plate has high wear resistance and good impact energy consumption, and can be cut, bent, welded, etc., to some extent, it can be directly connected by welding, plug welding, bolting, etc., in other structures. The maintenance site has the characteristics of time saving and convenience, and is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile industries, etc. Compared with other materials, it has high cost performance and has been received more and more. The more industries and manufacturers favor.

In the process of making wear-resistant steel plate, it is mainly 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 base body provides comprehensive properties such as strength, toughness and plasticity against external forces, and the wear layer provides wear resistance that meets the requirements of the specified working conditions.

The wear-resistant steel alloy wear layer and the matrix are metallurgically bonded. To a certain extent, it is mainly through special equipment, using automatic welding process, effectively welding high hardness self-protecting alloy welding wire on the substrate uniformly, the composite layer is one layer to two layers or even multiple layers, due to the alloy in the compounding process The shrinkage ratio is different, and uniform transverse cracks appear, which is a remarkable feature of the wear-resistant steel plate.
