Introduction:

Ferrosilicon purposes:
(1) used as a deoxidizer and alloying agent in the steel industry.
(2) used as the iron industry gave birth to the agent and nodulizer. Cast iron is an important modern industrial metal materials, it is cheaper than steel, easy to melt smelting, with excellent casting and much better than steel seismic capacity. Ductile iron, the mechanical properties at or near the mechanical properties of steel. A certain amount of ferro-silicon in cast iron to prevent the formation of iron carbide, and promote the precipitation of graphite and ball, and thus in ductile iron production, ferrosilicon is an important inoculant (to help the precipitation of graphite) and nodulizer .
(3) used as a reducing agent in the ferroalloy production. Chemical affinity between not only silicon and oxygen, low carbon content and high silicon ferrosilicon. Therefore, the high-silicon ferrosilicon (or silicon alloys) is commonly used as a reductant in the production of low-carbon iron alloy in the ferroalloy industry.
