Ferro Silicon (FeSi)


Ferro silicon (FeSi) is a master alloy made of silicon and iron. The production is based on silicon quartz, iron ore, coal, coke, and biocarbon. The alloy is mainly used as a deoxidant and an alloying element in the production of steel and cast iron which is achieved by:
  • A change in the chemical composition of the steel
  • The removal of harmful impurities such as Sulphur, Nitrogen, or Oxygen
  • A change in the solidification process, for example, upon inoculation.
Applications
Ferrosilicon has many applications in steel production and casting. It contributes to an increase in hardness, deoxidizing properties, corrosion resistance, strength, hardness, and thermal stability of products. It is also used for manufacturing inoculants which can deliver specific metallurgical properties to the final products.
  • Stainless steel: to resist corrosion, hygienic, aesthetic, and wear-resistance qualities
  • Carbon steels: used extensively in suspension bridges and other structural support materials and automotive bodies
  • Alloy steel: other types of finished steel
  • Deoxygenating in steel production
  • Reducer in the production of other Ferro alloys
  • Alloy element in producing steel & cast iron
