Ferroalloys purposes: as a reducing agent. Silicon alloys are used as the reductant production of molybdenum iron, vanadium iron and other iron alloy; and silicon-chromium alloys, silicon manganese alloys are used as a reducing agent in the production of low-carbon ferromanganese. Other aspects of the use. In non-ferrous metallurgy and chemical industry iron slag agent company, ferroalloys are also becoming more widely used. Ferroalloys Category: With the development of modern science and technology, ferroalloy varieties is growing. Single iron alloy. Only an alloy containing an alloying element is called a single alloy. Composite alloy. Multiple alloy containing two or more alloying elements. Press ferroalloy carbon content classification. Classification according to production method. Nitride products. Oxide mass.
