Metallurgical Material Ferrosilicon 10-50mm

The process of producing ferrosilicon begins with a mixture of coke and silica (or sand), which is then melted in the presence of any source of iron. Some of the most common sources of iron are scale and scrap iron. If the silicon content does not exceed 15%, ferrosilicon is obtained in blast furnaces lined with bricks for acid firing. If the silicon content is higher, an electric arc furnace is used. The most common compositions of ferrosilicon include silicon content of 15%, 45%, 75%, and 90%. The rest is iron, as well as about 2% calcium and aluminum. If there is a lot of silicon in the composition, this prevents the formation of silicon carbide.
