Graphite rotor is composed of two parts of rotor bar and nozzle. The transmission system drives graphite rotor rotation, argon or nitrogen via the rotor pole, aluminum melt blowing nozzle. High speed rotating graphite rotor into aluminum melt with argon or nitrogen scattered many small bubbles, which are dispersed in the liquid metal, and the rotation of the rotor to hydrogen and inclusions in Al melt diffusion, the bubble contact, bubbles in the melt by the gas pressure difference and surface adsorption principle, absorption melt the hydrogen adsorption and oxidation slag, and with the bubble was taken out of the melt surface, the melt will be purified. Graphite rotor speed can be adjusted by frequency converter to achieve stepless regulation,…
Pure graphite rod has high density, high strength, high purity graphite made, than ordinary graphite rod is to wear a little, but also relative wear resistance, some graphite products need to in the rotating device, so this requires ultra high pure graphite abrasion resistance, because there will be dust in repeated rotation friction thus, high purity graphite product itself is not very wear-resistant. Gao Chunshi said the high purity materials simple ink manufactured by high purity graphite of high purity graphite rods with the same specific, high purity graphite rod belongs to artificial graphite, graphite powder is called asphalt binder or coal oil coke after high pressure extrusion molding machine, and then after several high-temperature roasting and impregnation, the inside…
Graphite crucible materials selected for high pure graphite, high purity graphite is widely used in metallurgy, casting, mold and other industries, the production of high precision CNC machining equipment for horizontal continuous casting of high purity, high strength, high density graphite graphite mould mould; electronic industry; metallurgical industry by Shi Momo and other shapes, graphite processing products all kinds of parts can be realized, the machining precision and the roughness of the graphite demand. Performance of graphite crucible: 1, thermal stability: the use of the graphite crucible for emergency cooling, special design to ensure the reliability of product quality. 2, erosion resistance matrix design fine uniform, delaying the crucible erosion degree. 3, impact resistance: graphite crucible can withstand high heat…
