1. Introduction:
It 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.
