Graphite rotor spinning nozzle made of high purity graphite, in addition to considering the structure of the nozzle should break up the bubble, but also the use of molten aluminum alloy centrifugal force generated by agitation, melt into the nozzle and the level of gas emitted uniformly mixed to form a gas / stream discharge, increasing the contact area and contact time of the bubble and the liquid aluminum alloy to improve the degassing purifying effect. Graphite rotor speed can be realized through the inverter stepless speed control up to 700 r / min. Graphite rotor specifications for Φ70mm ~ 250 mm, impeller specifications for Φ85mm ~ 350 mm, high-purity graphite rotor antioxidant with high strength, high temperature, corrosion-resistant aluminum flow characteristics. In addition to the gas purification process, the inside surface of the liquid aluminum through the nitrogen blanket protection to the exposed portion of the aluminum rotor graphite solution in an inert gas to prevent the rotor temperature oxidation, to extend the service life of the rotor. Impeller shape is streamlined, the friction force between erosion resistance can be reduced rotation, the impeller and the liquid aluminum produced is relatively small. So that the outgassing rate of more than 50%, shorten smelting time, reduce production costs. Graphite rotor surface with a special anti-oxidation treatment, the service life is about 5 times that of ordinary products, widely used in aluminum casting industry. Graphite rotor aluminum foil used in the casting, alloy wheels and other aluminum industry in period of up to two months.
