Product Introduction
Silicon Carbon Alloy (Si-C alloy) is a cost-effective and efficient deoxidizer and alloying agent widely used in steelmaking and foundry industries. It is typically produced by smelting silicon-containing materials (like quartz) and carbon-based materials (like coal or coke) at high temperatures in electric arc furnaces.
This alloy is rich in Silicon (Si) and Carbon (C) and serves as an excellent substitute for traditional ferroalloys like ferrosilicon and recarburizers, helping steel mills reduce cost while improving metallurgical quality.
