Description
Ferrosilicon is an important alloy, which can remove oxygen from the steel in iron and steel production. and increase the final quality of the steel. Ferrosilicon is also the basis of pre-alloys for the manufacture such as fesimg for the modification of melted malleable cast irons.
Special grades of ferrosilicon such as low-alumina, high-purity, and low-carbon ferrosilicon, are used to produce special steel. The special grade of ferrosilicon can make the inclusion content and carbon content of the steel more low level than ordinary ferrosilicon.

Application
1)Ferrosilicon is often used as deoxidizer in steel- making.
2)In iron industry it can be used as inoculant and nodulizer.
3)It can be used as a reductant in ferroalloy production and chemical industry.
4)Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, nonf errous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
