Ferro Silicon is a ferro alloy consisting of iron and silicon,made by electric furnace smelting ,its raw material is coke, scrap steel, quartz (or silica ). As silicon and oxygen are easy to synthesize silica, ferro silicon is often used as deoxidizer in steel making.Meanwhile, due to the large amount of heat released during the production of SiO2, it is also advantageous to increase the temperature of the molten steel while deoxidizing. In the meantime, ferro silicon can also be used as an additive for alloy used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, Ferros ilicon is often used as reducing agent in ferro alloy production and chemical industry
