| Al (Aluminum) | ≤ 5% |
| C (Carbon) | ≤ 5% |
| S (Sulfur) | ≤ 0.1% |
| P (Phosphorus) | ≤ 0.05% |
| Size (mm) | 0–10mm, 10–50mm, etc. |
What is Ferro Silicon Slag used for in steelmaking?
In steelmaking, Ferro Silicon Slag is commonly used as a deoxidizer and alloy additive. It helps remove oxygen from molten steel, improves flow properties, and contributes to the desired chemical composition. Its lower cost compared to standard Ferro Silicon makes it a preferred choice for low-carbon and low-alloy steel production.
How does Ferro Silicon Slag reduce production costs?
Ferro Silicon Slag provides a budget-friendly alternative to standard ferroalloys. Its sufficient silicon content supports effective deoxidation and alloying, reducing the need for pure Ferro Silicon. This leads to:
Lower raw material costs
Improved material utilization
Enhanced yield in melting operations
When sourced directly from the factory, these cost advantages are even more pronounced.

What are the advantages of using high-quality Ferro Silicon Slag?
✅ Stable Chemical Composition – Ensures consistent metallurgical performance.
✅ Excellent Deoxidation Efficiency – Minimizes impurities and enhances steel purity.
✅ Improved Fluidity – Contributes to better casting and mold filling.
✅ High Silicon Recovery Rate – Reduces losses in the steelmaking process.
✅ Environmentally Friendly – Utilizes by-products and promotes sustainable practices.
