Ferroalloy production technology trends: The computer controlled electric furnace smelting process. With a computer-controlled electric furnace production process Jilin compound deoxidizer, such as ingredients, feed on materials, electrode pressure release, electric power conditioning, cooling water and control the flue gas purification system, can increase electric workloads and complex job rate Hebei deoxidizer, avoid operational errors caused by fluctuations in furnace conditions and equipment accidents. Ferroalloys: Classification according to production method. Blast furnace ferroalloys, including high carbon ferromanganese blast furnace, low-manganese alloys, ferrosilicon low; furnace ferroalloys, including high carbon ferromanganese, high-carbon ferrochrome, ferrosilicon, manganese alloys, silicon-chromium alloy, aluminum alloy, silicon calcium alloy, phosphorus iron, low carbon and low carbon ferrochrome, low carbon ferromanganese refining vanadium and iron.
