Ferrosilicon
Ferrosilicon is one of the most widely used ferroalloys in the steelmaking and foundry industries. Produced in electric arc furnaces from iron and silica, it acts as an effective deoxidizing and inoculating agent. Adding ferrosilicon enhances molten metal fluidity, reduces impurities, and improves the mechanical properties and durability of steel and cast iron. Ferrosilicon is available in various grades such as FeSi 75, FeSi 72, and FeSi 65, and is essential in applications including steel production, ductile iron, casting processes, and electrode manufacturing.
