Ferrosilicon is an alloy composed primarily of iron (Fe) and silicon (Si). It is produced by melting a mixture of iron ore, silicon dioxide, and coke or charcoal in an electric arc furnace. The resulting alloy is commonly used as a deoxidizer and an alloying agent in the production of steel, as well as in other industrial applications.
- Alloying element: Enhances material strength, hardness, and magnetic properties in steel and iron production, particularly for stainless steel, electrical steel, and specialty alloys.
- Deoxidizer: Reacts with oxygen and impurities in molten metal to prevent defects in final products through precipitation and diffusion deoxidation.
- Ball mill agent: Used as an alloying agent in nodular iron casting processes.
