Smelting process analysis of silicon metal
Silicon metal material is well used in our industry, and the material is usually classified according to the content of the three main impurities contained: iron, aluminum and calcium. The material is carbothermic, a method of smelting with silica and a carbonaceous reducing agent in a mineral heat furnace. The purity of the silicon metal product obtained in this way is relatively high and can reach ninety-seven to ninety-eight percent.
Silicon metal is mainly used in the metallurgical industry, silicon metal is mainly used quartz sand as raw materials for smelting, including quartz sand block making, preparation of furnace charge and smelting in mineral heat furnace several steps.
In general, good quality quartz sand will be used directly in the production of quartz glass products, silicon metal is also a method of production is in the electric furnace by the carbon reduction of silicon dioxide, the main ingredient silicon content of about 98%, the rest of the impurities for the iron, aluminum, calcium and so on. The main use is as an additive for non-ferrous alloys and as a starting material for the production of semiconductor silicon and silicone.
According to the percentage content of iron, aluminum, calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades, the wide application of the material, but also reflects the continuous development of China's industry, as a metallurgical materials manufacturer, the production of the product can meet the customer's requirements. And also widely praised, if you want to buy metallurgical materials, you can directly call us for advice.
