Silicon Carbide for Steelmaking Applications
Silicon carbide (SiC) for steelmaking is a high-efficiency material used as both a deoxidizer and recarburizer in modern steel production. With typical grades of 88% and 90% SiC, it helps improve molten steel purity, increase carbon recovery, and reduce alloy consumption.
It is widely applied in electric arc furnaces, induction furnaces, and converter steelmaking processes.
