What Is The Silicon Carbon Alloy Used in Steelmaking?

What is the silicon carbon alloy used in steelmaking?
This type of silicon carbon alloy serves as an additive in steelmaking-used to "detoxify" molten steel and adjust its chemical composition-and is primarily intended to replace traditional materials like ferrosilicon and silicon carbide.

Fixed composition: It consists mainly of silicon and carbon, with silicon content typically ranging from 35% to 70% and carbon content from 15% to 25%; the remainder is primarily iron.
Core functions: Added during converter steelmaking, it removes oxygen from the molten steel (deoxidation), increases carbon content (carburization), and refines the steel's grain structure, resulting in a stronger final product.
Advantages: Compared to traditional materials, it reduces the amount of alloy required, lowers steelmaking costs, improves the stability of the molten steel's chemical composition, and decreases the defect rate.
Primary production hubs: In China, production is concentrated in areas such as Anyang, Henan, which hosts a cluster of relevant manufacturing enterprises.
