Premium Ferrosilicon 70 72 75 FeSi Ferro Silicon: The Ultimate Reducing Agent for High-Efficiency Ferroalloy Production
Ferrosilicon is a high-grade ferro alloy composed of iron and silicon. This superior ferrosilicon alloy is meticulously crafted from coke, steel scraps, and quartz (or silica) smelted in an advanced electric furnace. Renowned for its ability to easily synthesize with oxygen into silicon dioxide, ferrosilicon serves as an exceptional deoxidizer in steelmaking processes. Additionally, the generation of SiO2 releases significant heat, thereby elevating the temperature of molten steel during deoxidation. Beyond its deoxidizing capabilities, ferrosilicon is an invaluable alloying element additive, widely utilized in the production of low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Its role extends to being a crucial reducing agent in ferroalloy production and various chemical industry applications.
