Chemical Engineering Wear Resistant Material ZQCr8 Chrome Steel Ball
Chromium alloy cast ball ZQCr8 Wear Resistant Material
Chromium alloy cast ball ZQCr8
High chromium alloy cast balls are widely used in powder preparation and ultra-fine deep processing in industries such as cement and building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coatings, light industry papermaking, magnetic materials, etc. The product has high hardness, low wear, good toughness, and less fragmentation. During use, the surface hardness of the sphere will be further improved, and the wear resistance will be enhanced. At the same time, it can improve the production capacity of the mill, increase the specific surface area of cement, and improve the recovery rate of concentrate.
