Ferroalloy industry has experienced three periods: the blast furnace and electric large-scale development period. Many new varieties of manganese alloy prices, such as high-grade ferrosilicon, calcium silicon alloy, tungsten, iron, molybdenum, iron, low carbon ferromanganese and ferrochrome came into being. These varieties can not produce manganese alloy supplier in a blast furnace, so the development of electric technology. Especially with the realization of long-distance transmission of manganese alloys, developed a large number of electric technology. Ferroalloy uses: alloy called for deoxygenation deoxidizer. Steel of various elements on the bonding strength of oxygen, namely oxygen capacity, from weak to strong in the following order: chromium, manganese, carbon, silicon, vanadium, titanium, boron, aluminum, zirconium and calcium. Thus, the general common ferroalloy steel deoxidation of silicon, manganese, aluminum, calcium composition.
