The main method of ferroalloy production: blast furnace process. The main equipment used in blast furnace blast furnace. Blast furnace ferroalloys production methods are used first. Blast furnace smelting ferroalloys and pig iron blast furnaces is basically the same. Blast furnace production of silicon metal powder alloy wholesale, has high labor productivity Buying metal fume, and low cost. The main method of ferroalloy production: electric furnace. Electric furnace 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.
