Metallurgical Grade Ferrosilicon for Steel & Foundry Applications
Why is FeSi 75 used as an inoculant in cast iron production?
In cast iron manufacturing, FeSi 75 (ferrosilicon 75% silicon) is widely used as an inoculant to control graphite nucleation during solidification.
  • Promoting fine and uniform graphite distribution
  • Reducing carbide formation (white iron tendency)
  • Improving machinability of cast iron parts
  • Stabilizing solidification structure
This makes foundry ferrosilicon essential in gray iron and ductile iron production systems.
How does ferrosilicon improve graphite structure in cast iron?
During cooling, carbon in molten iron forms graphite structures. FeSi influences this process by:
  • Increasing nucleation sites for graphite formation
  • Preventing coarse graphite flakes
  • Promoting spheroidal graphite in ductile iron
  • Improving structural uniformity
As a result, ductile iron FeSi inoculation leads to stronger and more consistent cast components.

Summary
Ferro Silicon FeSi 75/72 is a key metallurgical material used in both steelmaking and casting industries. It functions as a deoxidizer in steel production and as an inoculant in cast iron, improving graphite structure, reducing defects, and enhancing mechanical performance.
It is widely applied in:
  • Ferrosilicon supplier chains
  • Metallurgical grade FeSi alloy systems
  • Ductile iron and gray iron production
  • Steelmaking deoxidizer FeSi processes
