High Purity Ferro Silicon 75 Production
Low silicon ferro silicon 45 (FeSi 45), with a silicon content of 40%–47%, is commonly used as a deoxidizer and alloy additive in steelmaking and casting.
It offers a practical balance between cost and performance, providing sufficient deoxidation capability while maintaining stable composition control in industrial-scale production.
Chemical Properties of FeSi 45
Ferro silicon 45 typically contains a silicon content between 40% and 47%, providing balanced deoxidation performance in steelmaking.
| Element | Content |
|---|---|
| Silicon (Si) | 40% – 47% |
| Carbon (C) | ≤ 0.2% |
| Aluminum (Al) | ≤ 2.0% |
| Phosphorus (P) | ≤ 0.04% |
| Sulfur (S) | ≤ 0.02% |
The relatively lower silicon content makes FeSi 45 suitable for applications where cost control is important.
Physical Properties of Ferro Silicon 45
• Metallic luster with grey appearance
• Brittle structure, easy to crush into required sizes
• Good thermal stability during metallurgical processes
• Suitable for continuous industrial use
These properties allow FeSi 45 to be easily handled and applied in different production processes.
Metallurgical Properties of FeSi 45
FeSi 45 plays an important role in metallurgical processes:
• Acts as a deoxidizer to remove oxygen from molten steel
• Improves steel quality and reduces impurities
• Enhances casting performance and fluidity
• Provides stable alloying effects in steel production
Due to its balanced composition, FeSi 45 is widely used in large-scale industrial production.
