Ferro Silicon

1. Introduction: Ferro Silicon is the grey lumpish solid. It has very strong stabilities and does not place any chemical reaction in the dry air. 2. Usage: The ferro silicon is used extensively in the steel-making, casting non-ferrous metals and other industrial production, It is the good deoxidizer and most steel kind use the Ferro Silicon for Deoxidization,In steel smelting, It is used to sedimentary accretion and expanding deoxidizing, It is used to prove the strength, hardness and elasticity of steel greatly in steel casting.
