Ferro Silicon Alloy 72 Grade Solid Lumps Deep Grey Applied In Steel Desulphurization Works

Ferro Silicon Alloy 72 Grade Solid Lumps Deep Grey Applied In Steel Desulphurization Works
Ferro Silicon Alloy 72 Grade​ contains approximately 72% silicon​ with the balance iron and minimal impurities. It is produced as solid deep grey lumps, typically sized 10–80 mm, and is widely used in steel desulphurization​ processes to lower sulphur content and improve steel cleanliness.
Property
Typical Specification
Si content
~70–74% (nominal 72%)
Form
Solid irregular lumps
Color
Deep grey metallic
Impurities
Low Al, P, S
Main use
Desulphurization, deoxidation in steel
Key Features
  • Effective desulphurizer: Silicon reacts with sulphur in molten steel to form SiS, reducing sulphur-related hot shortness.
  • Solid lump form: Easy to handle in charging systems; resists dusting and breakage.
  • Deep grey color: Indicates proper reduction and low surface oxidation.
Benefits in Steel Desulphurization
  • Enhances steel fluidity and reduces inclusion formation.
  • Improves mechanical properties such as toughness and ductility.
  • Allows precise sulphur control in construction, pipeline, and automotive steels.
Typical Applications
  • Ladle desulphurization in integrated steel mills.
  • Combined deoxidation–desulphurization treatments before casting.
  • Alloying in high‑strength low‑alloy (HSLA) steel production.
