The main method of ferroalloy production: blast furnace process. Blast furnace ferroalloys production silicon metal prices, with high labor productivity and low cost. However, given the limitations of blast furnace hearth temperatures. As well as the conditions under blast furnace metal is carbon fully saturated. Therefore, generally used only for the production of blast furnace easily reducible element ferroalloy ferroalloy and low-grade silicon metal companies, such as high-carbon ferromanganese, ferrosilicon low, low silico-manganese, nickel, iron, and manganese-rich slag. The main method of ferroalloy production: reduction furnace is divided into electric (arc furnace) and two refining furnace. Reduction electric furnace: the furnace and the charge added to the charge electrode plug buried in buying silicon metal, rely on thermal resistance of the arc and arc current generated by the charge, conduct science arc smelting reduction operation. Molten metal and slag accumulation in the bottom and through the taphole timing of iron slag, the production process is carried out continuously.
