DESCRIPTION
The production of ferrovanadium, containing 35–80 percent vanadium, is carried out in an electric-arc furnace. Scrap iron is first melted, and a mixture of V2O5, aluminum, and a flux such as calcium fluoride or calcium oxide is added. In the ensuing reaction, the aluminum metal is converted to alumina, forming a slag, and the V2O5 is reduced to vanadium metal, which is dissolved in the molten iron.
Ferrous vanadium is a ferroalloy used in the iron and steel industry. It is mainly composed of vanadium and iron, but also contains sulfur, phosphorus, silicon, aluminum and other impurities.
