The core role of ferrosilicon alloy in the field of steel metallurgy

2025,12,29

As one of the indispensable raw materials in the steel industry, Ferrosilicon alloy plays a key role in modern metallurgical production. It is an iron silicon alloy made mainly from coke, steel shavings, quartz and other raw materials through electric furnace melting process.

One of the core functions of ferrosilicon in steelmaking is to serve as an efficient deoxidizer. Due to the good binding ability between silicon and oxygen, it can effectively remove oxygen from molten steel and improve the quality of steel. Meanwhile, the reaction process is accompanied by heat release, which helps to maintain or increase the temperature of the molten steel.

In addition, ferrosilicon is also an important alloying element additive, widely used in the production of various special steels such as structural steel, tool steel, spring steel, heat-resistant steel, and electrical steel, which can significantly enhance the strength, hardness, and elasticity of steel.

Practice has shown that the use of ferrosilicon not only meets the deoxidation requirements of clean steel smelting, but also has a positive effect on improving the morphology of inclusions in steel and reducing gas content, which helps to enhance product quality and production efficiency.

In the field of steel materials, in addition to steelmaking applications, silicon iron powder that has been atomized or ground can also be used as an important component of steel ingot insulation materials, which helps improve the quality of steel ingot forming and increase product yield.
