Ferroalloy production technology trends: the use of advanced production technology. Continuous smelting calcium alloy, one-step metallurgical silicon chromium alloy, heat exchange method (Bohlen method) production of low-carbon ferromanganese and low carbon ferrochrome and other production processes Jilin compound deoxidizer, shorten the process, reduce energy consumption improve production efficiency, and reduce production consumption and costs. The use of fine materials technology. Concentrate ferroalloy production technology is an important part of production and consumption reduction. Such as the use of high-quality combination of carbonaceous reductant, with gas coal and bituminous coal Hubei complex deoxidizer, instead of part of the metallurgical coke; sintered ore, pellets, iron ore pellets, iron pellets and other scales Jiangsu composite deoxidation agents, improved ore preparation technology into the furnace and the furnace conditions, thereby increasing productivity. Iron alloy is an alloy composed of one or two or more fused metallic or non-metallic elements and iron together. For example, silicon and iron Fe2Si ferrosilicon is formed, Fe5Si3, FeSi, FeSi2 silicide, etc., which are the main components of ferrosilicon, ferrosilicon and silicon mainly FeSi FeSi2 form, in particular FeSi more stable.
