The main method of ferroalloy production: Ferroalloys production silicon barium calcium plant in many ways, most of ferroalloy products using pyrometallurgical production. Depending on the smelting equipment, methods of operation, and heat sources. By Device use. Use of the device can be divided into the blast furnace, electric furnace, furnace extrajudicial, converter and vacuum resistance furnace. The main method of ferroalloy production: blast furnace process. Blast furnace production silicon barium calcium alloy manufacturers, 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 alloy and low-grade iron alloy, such as high-carbon ferromanganese, ferrosilicon low, low silico-manganese, nickel, iron, and manganese-rich slag.
