Ferrosilicon

Product Details

产品名称: Ferrosilicon

Ferrosilicon is an iron alloy composed of iron and silicon. It is produced by smelting iron and silicon ores—using coke, steel scrap, and quartz (or silica) as raw materials—in an electric arc furnace. Because silicon readily combines with oxygen to form silicon dioxide, ferrosilicon is commonly used as a deoxidizer in steelmaking; moreover, the substantial heat released during the formation of SiO₂ helps raise the temperature of the molten steel. In addition, ferrosilicon serves as an alloying element, widely employed in low‑alloy structural steels, spring steels, bearing steels, heat‑resistant steels, and electrical silicon steels. In both ferroalloy production and the chemical industry, ferrosilicon is frequently utilized as a reducing agent.
