The main method of ferroalloy production: oxygen converter method. The main equipment for BOF converter method uses silicon calcium powder, calcium silicon powder according Oxygenation offer, 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 alloy of high carbon into the converter, high-pressure oxygen into the furnace through the lance through blowing high calcium silicon powder, rely on thermal oxidation decarbonization calcium silicon powder wholesale release, production is carried out intermittently. The main method of ferroalloy production: classification by heat source. Depending on the heat source is divided into carbon thermal method, heating method, silicon thermal power, metal calorimetry. Carbon calorimetry. Carbon heat source method of smelting process is mainly the burning hot coke, coke as a reducing agent, the reduction of oxide ore using this method of production is carried out continuously in a blast furnace.
