High-Grade Ferro Silicon 75 Lump 5–10cm for Steelmaking and Ferroalloy Production
High Quality 5–10 cm FeSi75% Iron-Silicon Lumps are a critical alloy used in steelmaking, ferroalloy production, and metal casting. These lumps contain 75% silicon content and are produced by heating a mixture of coke, steel scrap, and quartzite in electric furnaces. They play a significant role in the deoxidation of steel, helping to improve the steel's quality by removing impurities and enhancing the alloy's strength. Typically used in the steel industry, FeSi75% serves as both a deoxidizer and alloying agent.
This product is an essential ingredient in steel manufacturing processes, with approximately 3-5 kg of Ferro Silicon 75 used to produce every ton of steel. The 5–10 cm lump size ensures optimal melting behavior and furnace efficiency.
