Ferrosilicon introduction

Ferrosilicon is an iron-silicon alloy composed of two elements, iron and silicon, and is an important alloy variety in the smelting industry.

Ferrosilicon is made of coke, steel scraps, and quartz (or silica) in an electric furnace. Traditionally, ferrosilicon is made by reducing silicon from silica containing SiO2. Most ferrosilicon smelting uses metallurgical coke as a reducing agent, and steel scraps are a regulator for ferrosilicon. In addition, the ferrosilicon production process also includes the introduction of chlorine and oxygen into the molten ferrosilicon to remove as many impurities as possible from the molten ferrosilicon.
