The main method of ferroalloy production: electric furnace. Electric furnace silicon metal prices is the main method of production of ferroalloys, its production accounts for about 4/5 of all ferroalloy production, the main device used in an electric furnace. Reduction electric furnace is divided into (submerged arc) and refining furnace two kinds. Reduction furnace (submerged arc) method. Reduction furnace method is based on carbon as a reducing agent ferroalloy ore production. Iron alloy is also used to produce other metal thermal reduction reducing ferroalloy and nonferrous metal silicon production, non-ferrous metal alloy additive; also a small amount for the chemical industry and other industries; steelmaking: All steel is an alloy of It also makes the alloy is the most widely used, the largest amount of alloy.
