Silicon Metal production process
Silicon metal is the important raw materials of modern industry. it's the major raw materials of aluminum alloy ingots, polycilion and silicone.
Each process of silicon metal production ,starting from preparing raw materials , cleaning the quartz, smelting, casting, crushing into pieces, testing, weighing, packaging & shipment, is controlled strictly so as to make sure the quality .
