Ferroalloy production technology trends: the use of advanced production technology. Continuous smelting calcium alloy, one-step metallurgical silicon chromium alloy, heat exchange and production of low-carbon ferromanganese, low carbon ferrochrome and other production processes Hubei steel Deoxidants, shorten the process, reduce energy consumption steelmaking complex deoxidation agents, improve production efficiency, and reduce production consumption and costs. The main method of ferroalloy production: blast furnace process. Tianjin Ferroalloy production of blast furnace steelmaking Deoxidants, 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.
