The correct or incorrect operating method of graphite crucible will impact its service life directly , it need the coordination with crucible furnace when we use the graphite crucible, now ,we introduce the relationship between the graphite crucible and crucible furnace. The graphite crucible and the crucible furnace can not be separated. the application environment of graphite crucible become more and more brutal when we improve the working efficiency of the crucible furnace. On the contrary, the performance and the shape of the crucible furnace have been changed because of the quality improvement of the graphite crucible and the beginning of the large-scale crucible. In recent years, with the continuous improvement of environmental equipment of foundry machinery, the continuous improving…
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…
