Applications of Ferro Silicon 75%
a. Steelmaking
FeSi 75 is an effective and widely used deoxidizer, helping to:
remove oxygen from molten steel
improve steel purity
enhance strength, hardness, and toughness
stabilize the steel structure
It is used in carbon steel, alloy steel, stainless steel, and special steel production.
b. Foundry & Cast Iron
In the foundry industry, FeSi 75 functions as:
a silicon additive for cast iron
a base material for inoculants
an essential input for ductile iron production
It improves mechanical properties, enhances fluidity, reduces shrinkage defects, and refines graphite shape.
c. Inoculant & Nodularizer Production
FeSi 75 is the main raw material for:
FeSi–Ba inoculants
FeSi–Ca inoculants
FeSi–Mg nodularizers
d. Magnesium Production (Pidgeon Process)
Used as a reducing agent in magnesium smelting.
