Silicon carbide (sic) deoxidizer 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, and the deoxidation time is shortened and saved. Energy, improve steelmaking efficiency, improve quality, reduce consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and improve the comprehensive economic benefits of electric furnaces are of great value.
