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, shorten the process of Tianjin Steel Deoxidants, reduce energy consumption steelmaking complex deoxidation agents, improve production efficiency, and reduce production consumption and costs. Alloy is an alloy of iron and other elements of the composition. In addition to silicon, manganese, chromium, ferroalloy and other three systems ferroalloy, but also includes some pure metal, silicon composite alloy, inoculant, the ball like alloy. Ferroalloy mainly used as an additive steelmaking deoxidizer and alloying elements.
