Black Silicon Carbide Grains For Waterproof Abrasive Paper

 

Product Description

Silicon Carbide

Silicon carbide includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.

Applications

Silicon carbide is a new type of strong composite deoxidizer, which replaces the traditional silicon powder carbon powder for deoxidation. Compared with the original process, the physical and chemical properties are more stable, the deoxidation effect is good, the deoxidation time is short, energy saving, and steelmaking efficiency are improved. , Improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and increase the energy and economic benefits of electric furnaces.Silicon carbide balls are wear-resistant, non-polluting, improve the stability of raw materials, reduce the thickness of the mill and the volume of the balls, and increase the effective volume of the mill by 15%-30%.
