The decription of High graphitic cathode carbon block

High graphitic cathode carbon block
A high graphitic cathode carbon block, including aggregate, asphalt binder, characterized in that the cathode carbon block is the roasting pieces of the particle size of less than 8 mm, 30-60% Electrically Calcined Anthracite 15 to 30%, 10 -50% graphite and 15-25% asphalt. An aluminum cell with graphite cathodes. The main component of the graphite cathode carbon block carbon, characterized in that made ​​of natural graphite as the aggregate.

Full-graphitic cathode carbon block and graphite of cathodes:
Integrated production efficiency, power consumption and furnace life factors in the electrolytic aluminum process, the aluminum maker, has begun full-graphitic cathode carbon block or graphite cathodes puzzle system electrolyzer.
Full-graphitic cathode carbon block, also known as 100% graphitic cathode carbon block, graphite (crushed) or graphite petroleum coke as raw material, made ​​of aluminum after forming, sintering, machining carbon products, and semi-graphite carbon block, with high thermal conductivity, low specific resistance characteristics.
However, the use of graphite powder (crushed) for raw materials, 100% graphite quality cathodes, because of the raw materials for graphite electrodes processing waste and recycling waste, the consistency of the product.
Graphite cathodes calcined petroleum coke as raw materials, molding, baking, impregnation, and then calcined by graphite furnace (ohmic heating to 2500 ~ 2700 ° C) made ​​of aluminum graphitization of carbon products, the specific resistance low (generally 10 ~ 12μΩm), high thermal conductivity, real density, bulk density, low porosity characteristics, with its puzzle system electrolyzer, corrosion resistance, long life, low power consumption of the electrolysis process.
100% graphite cathode carbon block and graphite cathodes on the surface are graphite products, technical indicators are similar, but different materials, different process routes, therefore, the internal structure is different, in fact, two different products .
