Description
Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.
Application
1. Ferrosilicon is often used as deoxidizer in steel- making.
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
3. It can be used as a reductant in ferroalloy production and chemical industry.
4. In iron industry it can be used as inoculant and nodulizer.
