About Ferro Silicon
Ferro Silicon is an alloy of iron and silicon, typically containing 15% to 90% silicon. It is produced by reducing quartz or sand with coke in the presence of iron in a submerged arc furnace. The resulting alloy is a versatile material used extensively in steelmaking and casting processes.
Ferro Silicon is an indispensable component in steel production, offering numerous benefits that enhance the quality and performance of steel. Ferro Silicon is an alloy of silicon and iron. Silicon acts as a strong oxidant and is used primarily in special steels and in small quantities in mild steel.
