Our company mainly produces 17mm-150mm low, middle, high chrome alloy casting iron ball. Huafu chose large angle steel, scrap steel and other raw material, according to different product, needs adding chrome, manganese, vanadium, titanium, rare earth and as so on metal. Products high hardness, low wear, good toughness and less broken, in the process of using spherewill further improve the surface hardness, wear resistance.
Chrome alloy casting iron ball are widely used in cement, buildingmaterials, metal mining, coal slurry thermal power, chemical engineering, ceramic coating, light industry, papermaking, ultrafine powder preparation of magnetic materials and other industries and further processing.
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.
