High Purity Silicon Slag Briquettes
Product Description
High Purity Silicon Slag Briquettes are engineered as an economic deoxidizer and alloy additive for steelmaking and casting. Compared to traditional FeSi, they significantly reduce per-ton steel costs while delivering stable silicon content (60-68%), ideal for buyers who don't require ultra-high purity but prioritize cost-efficiency. Our briquettes are sintered at high temperature for high hardness and low breakage, with precise sizing for direct feeding into EAF or BOF furnaces - reducing manual labor and boosting production efficiency.
Chemical Composition Table
| Element | Content Range | Buyer Focus |
| Si | 60%-68% | Core index - meets most steelmaking/casting needs with optimal cost-performance. |
| Fe | Balance | Base carrier - controls density and melting rate within optimal range. |
| Al | ≤ 2.5% | Controlled to avoid impacting steel cleanliness. |
| C | ≤ 2.5% | Suitable for common carbon steel - fully acceptable outside special steel. |
| S | ≤ 0.06% | Meets industrial grade - no impact on mainstream steel quality. |
| P | ≤ 0.06% | Strictly monitored to prevent inclusion formation. |
