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.
