High Carbon Silicon
High carbon silicon lumps serve as an efficient alloy with elevated silicon and carbon content, ideal for deoxidizing molten steel, adding carbon, and lowering production costs in converter processes. This material effectively substitutes traditional ferrosilicon, silicon carbide, and carburizing agents.

Product Uses
High carbon silicon (HCFeSi) is a versatile and economical alloy widely used in steelmaking as an effective deoxidizer and carbon additive. It helps remove oxygen from molten steel, releases heat to stabilize furnace temperatures, and precisely adjusts carbon content to enhance steel strength and toughness. In foundry applications, it promotes uniform graphite formation in cast iron, reducing defects and improving casting quality and machinability.
FAQ
