Ferrosilicon 45 (FeSi45) is manufactured from semi-coke, silica, steel waste and other materials. The production process entails smelting in an open or semi-closed continuous reduction furnace.
Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is an alloy produced in an electric furnace using coke, steel scraps and quartz (or silicon dioxide) as raw materials. Due to the ease with which silicon and oxygen combine to form silicon dioxide, ferrosilicon is frequently employed as a deoxidiser in steelmaking. Furthermore, the formation of silicon dioxide generates a considerable amount of heat, which can be employed to simultaneously elevate the temperature of the molten steel. Furthermore, ferrosilicon can be used as an alloying additive in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is frequently employed as a reducing agent in the manufacture of ferroalloys and in the chemical industry. The ferrosilicon alloy comprises iron and silicon, with the raw materials being silicon dioxide, steel and coke. Silicon melts into molten iron after high-temperature reduction at 1500-1800 degrees Celsius to form ferrosilicon. It is the most significant type of alloy in the smelting industry.
