Natural Lump Silicon Slag 50% Si

Mingrui Silicon's Natural Lump Silicon Slag is the residual product from silicon metal smelting, containing 45%-65% silicon along with controlled C, S, P, and Al. Unlike processed powders, our natural lump form (10-100mm) retains the original metallurgical structure, offering stable and predictable deoxidation performance in molten steel. As a direct substitute for ferrosilicon, it helps steel mills reduce alloy costs by 20-30%. We maintain strict quality control with in-house spectrometer testing, ensuring Si content fluctuation within ±2%. With a monthly capacity of 2000MT and 500MT spot stock, we guarantee stable long-term supply for global steel producers.

Our Silicon Slag features a wide range of Silicon (Si) content from 45% to 65%, designed as a cost-effective solution for steelmaking. Key advantages include controlled low levels of impurities, specifically Aluminum (Al) and Carbon (C) ≤ 5%, and ultra-low Phosphorus (P) and Sulfur (S) ≤ 0.05%, ensuring high-quality deoxidation performance.

why choose our products

 

1.Direct Furnace Lump:​ Unprocessed natural form preserves original silicon structure for stable deoxidation.

2.Significant Cost Saving:​ 20-30% cheaper than standard FeSi 75, directly reducing steelmaking cost per ton.

3.Controlled Impurities:​ S <0.05%, P <0.05%, safe for medium-to-high grade steel.

4.Flexible Sizing:​ 10-100mm natural lumps, or customized crushing to 10-50mm / 0-10mm per request.
