High purity silicon metal is a prerequisite for good operation
Quartz rock is used as raw material to produce chemical silicon metal and low ash carbon material is used as reducing agent. The main raw materials for producing silicon metal for chemical use by electric furnace process are silica and carbon raw materials. Carbon raw materials and petroleum coke, high quality anthracite or charcoal, can also be mixed with a part, in order to increase the furnace charge ratio resistance. The raw materials are required to have the necessary purity and good reaction ability to meet the product specifications; Reductant has different reaction ability, in order to be able to fully react with quartz stone; Burden has different composition, and there are different granularity, so that through the appropriate coordination, the charge electric furnace has a good impact.
Our company is the production of silicon metal manufacturers, if you need silicon metal please contact us.
