The metal powder vendor usage quartz rock as resources, low-ash carbonaceous material as reductant to produce chemical metal silicon. Electric heating system generate chemical silicon, the raw materials mostly silica as well as carbon products. Carbon resources again petroleum coke high quality anthracite or charcoal, can additionally be combined with a part, to boost the cost resistance. Raw materials need required pureness, excellent response, in order to attain the product specifications; decreasing agent has a different response, in order to have an appropriate response with quartz; heating system concern with various active ingredients, as well as with different granularity, in order to with the adequate coordination make the electrical heating system with good result.
silicone rubber wholesaleof silicon oxide mineral smelting metallic silicon is a no slag procedure, chemical silicon smelting is with rigid selection of silica, not just the content of pollutants is much less, but likewise requires a high mechanical stamina, and also sufficient thermal security, an ideal fragment size composition. Chemical silicon smelting is much better to select silica. The all-natural form of silicon oxide or exist in independent quartz minerals, or is almost wholly right into the rock by the silicon oxide item - silica, or silica morphology sandstone. Manufacturing of chemical silicon consisting of contaminations in the silicon oxide mineral and sticky product in the smelting process as well as some entirely recovered, as well as some parts are brought back, some compound kind going into the item silicon or born slag. This is not only increases power intake, lower item top quality, trigger troubles to the smelting process.
Silica into the furnace is needed to have a certain fragment size. Silica particle size is a crucial procedure of smelting. Silica appropriate bit dimension influenced by silica types, furnace capability, handling conditions, as well as the lowering representative as well as the fragment size as well as other factors, it is figured out to the details conditions of smelting. Carbonaceous minimizing agent, the main reducing agent of chemical silicon smelting, petroleum coke, bituminous coal, charcoal. In order to raise the burden of the resistivity and also enhance the chemical task, also with gas coal, silica naphthalene, blue, charcoal, semi-coke, reduced temperature coke, pieces of wood. In the chemical components of the carbonaceous decreasing representative, mainly need to be considered fixed carbon, ash, unstable issue as well as dampness. General needs for set carbon, decrease the reductant total amount needed, thus much less ash right into the pollutants, a corresponding decrease in the amount of slag, lowered power intake, minimized chemical silicon contamination content. The resistivity of the carbonaceous lowering agent to be large, the porosity to be high. The heating system problem resistivity depends mainly on the carbonaceous reductant. The greater carbonaceous reductant resistivity, the better chemical task, and also the high recovery rate of the silicon power.
