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. The main method of ferroalloy production: oxygen converter method. The main equipment used for the BOF converter method, according to the way of high-quality silicon carbide powder oxygen 75 #, there are top, bottom, side and top and bottom-blown blowing method. The raw materials used in liquid high carbon ferro alloys, pure oxygen, coolant and slagging materials. The liquid high carbon alloy of silicon carbide powder into the converter 75 # price, high-pressure oxygen into the furnace through the lance through blowing, relying on the oxidation reaction of the exothermic heat removal, the production is carried out intermittently.
