50-100mm FeSi45 For Steel Making

50–100mm FeSi45 is produced by melting high-purity silica and iron in an electric furnace and casting the alloy into large, dense blocks. The 50–100mm size range is specifically designed for steel mills that prefer slow-melting alloy additions for precise silicon control during refining.

The FeSi45 grade contains approximately 45% silicon, offering balanced metallurgical activity ideal for general steel production. Its controlled silicon content supports stable deoxidation and contributes to a cleaner molten metal bath. Because of the large lump size, FeSi45 dissolves gradually, reducing silicon spikes and enabling steelmakers to maintain consistent alloying conditions.

This material is widely used in BOF and EAF operations where large-size ferroalloy additions help regulate furnace temperature and support long-duration melting cycles. FeSi45 also improves heat transfer efficiency, enhances slag–metal interaction, and assists in adjusting steel fluidity depending on production requirements.

The alloy is known for its low impurity levels and reliable melting behavior, making it a dependable choice for carbon steel, structural steel, and general construction steel production. Each batch is inspected for silicon content, impurity control, density, and particle uniformity to ensure stable metallurgical performance.
