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.

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.
