:Chemical Formula and Composition
:The general chemical formula of Ferrosilicon is
FeSiₓ (where x typically ranges from 0.75 to 0.9 for high-purity grades)
- | Element | Composition Range (%) |
---|---|---|
Silicon (Si) | 75.0 – 90.0 | |
Iron (Fe) | Balance | |
Aluminum (Al) | ≤ 1.5 | |
Calcium (Ca) | ≤ 0.5 | |
Carbon (C) | ≤ 0.2 | |
Sulfur (S) | ≤ 0.02 | |
Phosphorus (P) | ≤ 0.03 |
:Production Method of Ferrosilicon Extra
Ferrosilicon Extra is manufactured in submerged arc furnaces using high-quality raw materials like silica (SiO₂) and iron ore or steel scrap. The process involves
:Reduction Reaction✅
SiO2+2C→Si+2CO
Fe2O3+3C→2Fe+3CO
:Alloy Formation✅
Iron and Silicon combine under extreme temperatures (2000°C+) to form FeSi
:Refining & Purification✅
Advanced purification removes impurities to create Extra-grade ferrosilicon
