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. 

Ferro silicon is widely used in the steel making,iron casting ,low-carbon ferroalloy producing:

   1 In the steel making field,Ferro silicon 75 / 65  is used as deoxidizer and alloying agent to precipit and diffuse deoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel.

   2 In the iron casting,it is used as ball mile agent and alloying agent especially in the nodular iron casting, Adding ferrosilicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.then the mechanical capacity can be the same of steel's.

   3 High-silicon ferrosilicon can be used for the production of the low-carbon reductant in ferro alloy industry.

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, bering steel, heat-resistant steels and electrician silicon-steel.

3  Ferrosilicon commonly used as a reductant in ferroalloy production and chemical industry.

4 In iron industry it often used as inoculants and nodulizer and deoxidizer.
