DESCRIPTION
Ferrosilicon is an alloy product mainly composed of iron, silicon, and small amounts of carbon, aluminum and other elements. The silicon content of ferrosilicon is usually between 70% and 75% and can be adjusted according to the needs. Ferrosilicon is an important iron alloy widely used in the steel industry for deoxidation, alloying and improving the quality of steel. In addition, ferrosilicon can also be used to prepare silicone rubber, semiconductor materials and other products.
