Specifications

Ferro Silicon 72% & 75%.It is used extensively in the steel-making, casting non-ferrous metals and other industrial production.I

1, Features:
The appearance of Ferro Silicon is the grey lumpish solid. It has very strong stabilities and does not place any chemical reaction in the dry air.

2, Application:
It 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.
