    Black Silicon Carbide Powder

    Black Silicon Carbide, also know as Black SiC, is produced in an electric resistance furnace from quartz sand and petroleum coke at high temperature. The hardness and sharp particle of this material make it suitable for manufacturing of grinding wheels, coated products, wire saws, superior refractory materials and deoxide as well as for lapping, polishing and blasting.

    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%.
