Silicon iron block is an iron alloy composed of iron and silicon. Silicon iron blocks are made by smelting coke, quartz (or silicon dioxide) as raw materials using an electric furnace. Due to the easy synthesis of SiO2 from silicon and oxygen, silicon iron is commonly used as a deoxidizer in steelmaking. Ferrosilicon can also improve the purity of molten iron; Generate water-insoluble compounds with low melting point impurities such as arsenic, zinc, tin, and lead.
Silicon iron blocks have many functions and special roles in various fields① Deoxidizer in steelmaking. ② Alloy element binders are widely used in low-alloy steel, non-ferrous metals, bearing steel, heat-resistant steel, and electrical silicon steel.③ Reducing agents in ferroalloy production and chemical industry.④ In the steel industry, it can be used as an inoculant and spheroidizing agent.
