Introduction of silicon slag
1、 Production Silicon slags are the remains of the manufacture of silicon metal,the main content of which is Slicon (45%-95%). They are susually treated as waste. 2、 Useage Acturally they can be widely used in indusrtial processes, such as to be used as a good substitute for ferro silicon in steel making, which may considerably reduce production cost and resource waste. They can also be made into silicon ball and then to be used as deoxidizer and heat-riser in steel making and casting. 3、 Category As we all know, silicon slags are by-products made during silicon smelting. According the places where they are formed in the furnace, silicon slags may be sorted as : (1) Scum (floating on the surface of melting silicon ) : Si :30-40% C :8-15% Fe:1.5-2.5% (2) Normal Silicon slag (formed between scum and melting silicon): Si:45-80% C:8%max Fe:1.5-2.5% Al:6%max Ca:5%max S:0.05%max P:0.04%max (3) High-carbon Slicon (precipitated on the b...
