The main method of ferroalloy production: electric furnace. Ferroalloy electric furnace is the main method of producing silicomanganese ball wholesale, with its output accounting for about 4/5 of Buying silico-manganese ferroalloy production sphere, the main equipment used is 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. The main method of ferroalloy production: refining furnace (EAF) method. Refining furnace method is to use silicon (silicon alloy) alloy products, relying on heat and electric arc smelting silicon-oxygen reaction heat. Charge is added from the roof or the furnace door, the whole process is divided into arc smelting, feeding, melting, refining and iron and other five processes, the production is carried out intermittently.
