The crack of Chromium Carbide composite wear-resistant plate means that there will be many cracks on the surface of the composite wear-resistant plate. The reason of the crack is that the chromium carbide composite wear-resisting plate is produced by welding. In the course of welding production, because of the high temperature (about 2000-4000 degrees) , the chromium carbide composite wear-resisting plate will produce a lot of welding stress. Welding stress is a harmful thing, if it is not eliminated in time, it is easy to break and crack in later use. The surface crack of chromium carbide composite wear-resistant plate is the result of welding stress release. That is, the formation of cracks, resulting in chromium carbide composite wear-resistant plate in the production process of welding stress release. In this way, chromium carbide composite wear-resistant plate will not occur deformation, fracture and other problems. Chromium Carbide composite wear-resistant plate produced by welding process, belongs to the metallurgical combination, the combination of excellent performance. The crack will not fall off or break in the process of using.
