Surfacing wear-resistant composite steel plate is a modern new type of composite wear-resistant steel plate material. It has been popularized and used in industrialized countries since the 1960s. With the advancement of science and technology in our country and the needs of market economic development, the special properties and practical economic value of wear-resistant cladding composite steel plates have gradually been recognized and used by forward-thinking managers of some large industrial and mining enterprises, and have created new opportunities for the enterprises. Considerable economic benefits.
The comprehensive properties of surfacing wear-resistant composite steel plates are as follows:
1. Extraordinary anti-wear performance ratio: Wear tests show that the wear resistance of surfacing wear-resistant composite steel plate is 10-30 times higher than ordinary steel plates, 5 times higher than cast stainless steel and high manganese steel, and better than cast high-chromium iron 1 times higher, roughly the same as ceramics. HRC≤63
2. High impact performance ratio: Since the base material is made of Q235A mild steel substrate, the surface is made of chromium carbide multi-element wear-resistant surfacing composite super-hard material. It fully reflects the dual advantages of composite materials with both extraordinary wear resistance and impact toughness. This is beyond the reach of cast wear-resistant materials. (Traditional castings have poor impact resistance and are brittle and easy to break)
3. Convenient processing performance ratio: Maintenance workers can cut and shape materials according to on-site dimensions (plasma cutting). It is very convenient to weld the wear-resistant steel plate to the surface of the wear parts (carbon steel surface), and it can also be processed into countersunk holes. Bolted to the component. It can also be formed by inward cold bending, such as wear-resistant pipes, dust removal elbows, various special-shaped sky and round places, and other plate components. (Surfacing wear-resistant composite steel plate cannot be assembled by welding, and it is difficult to cast large-area wear-resistant plates from cast steel. In addition, traditional castings are very heavy because they are designed with reinforcing ribs to prevent deformation.)
