75/65 Fesi Ferrosilicon Visible Impurities For Steelmaking And Cast
Iron
Ferrosilicon is predominantly composed of iron (Fe) and silicon
(Si), forming an alloy that is created through the smelting of a
combination of iron ore, coke (carbon), and silica in an electric
arc furnace. The silicon content of ferrosilicon varies between
approximately 15% and 90%, depending on the specific purpose for
which it is being used.
Ferro Silicon Function
Desulfurizing agent: In some instances, ferrosilicon can be
utilized as a desulfurizing agent. It reacts with sulfur present in
molten metal, forming a slag that can be removed, thereby reducing
the sulfur content in the final product.
Inoculant: Ferrosilicon can act as an inoculant in the casting
process. It helps control the formation and distribution of
graphite flakes in cast iron, improving its mechanical properties
and reducing brittleness.
Deoxidizer: Ferrosilicon is commonly used as a deoxidizing agent in
the production of steel and cast iron. It reacts with oxygen and
other impurities present in the molten metal, reducing them and
preventing the formation of defects in the final product.

Product Applications
1. In the steel making field, Ferro Silicon 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. Ferro silicon is used as a reducing agent in the production of
ferroalloys
4. High-silicon ferro silicon can be used for the production of the
low-carbon reductant in ferro alloy industry.
5, In addition ,ferro silicon powder can be used as a suspended
phase in the mineral processing industry and coatings for welding
electrodes in the electrode manufactruing.
