Premium Ferrosilicon 70, 72, 75 FeSi for Optimal Reducing Agent in Ferroalloy Production
Ferrosilicon is a high-performance alloy composed of iron and silicon, meticulously crafted using coke, steel scraps, and quartz (or silica) in an electric furnace. This extraordinary material is highly valued in steelmaking for its superior deoxidizing properties, as silicon readily bonds with oxygen to form silicon dioxide. The exothermic reaction further elevates molten steel temperatures, enhancing the deoxidization process. Additionally, ferrosilicon serves as an essential alloying element, finding extensive applications in the production of low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Its versatile use as a reducing agent is crucial in ferroalloy production and various chemical industries.
