Application
Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is made of iron silicon alloy made of coke, steel chips, quartz (or silica) as raw material and smelted by electric furnace. Because silicon and oxygen are easy to combine into silicon dioxide, so ferro silicon is often used as deoxidizer in steelmaking. At the same time, due to the release of a lot of heat when SiO2 is generated, it is beneficial to improve the temperature of molten steel at the same time of deoxidation. At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, heat resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, often used as a reducing agent.Role of ferrosilicon alloy: (1) used as deoxidizer and alloy agent in steelmaking industry. (2) used as inoculant and spheroidizing agent in the cast iron industry. (3) as reducing agent in ferroalloy and magnesium production.
