Ferrosilicon 70 72 75 FeSi Ferro Silicon - The Ultimate Reducing Agent for Premium Ferroalloy Production
Ferrosilicon is a sophisticated ferroalloy composed of iron and silicon. This high-quality alloy is crafted from coke, steel scraps, and quartz (or silica), smelted meticulously in an electric furnace. Owing to the affinity between silicon and oxygen, ferrosilicon is extensively utilized as a vital deoxidizer during the steelmaking process. The formation of silicon dioxide (SiO2) releases substantial heat, thereby elevating the temperature of molten steel while effectively deoxidizing it. Furthermore, ferrosilicon serves as an essential alloying element additive, finding widespread application in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Its role as a reducing agent extends to the realms of ferroalloy production and the chemical industry, making it indispensable.
