ferro silicon manufacturing process
The current domestic production of high quality silicon method, there are mainly five kinds, one is produced by selection of furnace charge high purity ferrosilicon , 2 it is to adopt the method of blowing chloride refining outside the furnace production of high purity and low carbon ferrosilicon , 3 it is to adopt the method of top blowing oxygen outside the furnace production of high purity and low silicon, aluminum four is adopt the method of thermal shock slag washing production of high purity and low carbon ferrosilicon, five is to adopt the method of selection of furnace charge low aluminum, low carbon ferrosilicon production Ferrosilicon is a silicon-iron alloy composed of silicon and iron in a certain proportion and is mainly used for steelmaking, casting and other ferroalloy production. Ferrosilicon will react deoxygenation with steel, formula as: 2FeO+Si=2Fe+SiO2. So as to deoxidize oxygen and improve the quality of steel, including enhance the hardness, int...
