High graphitic cathode carbon block
Graphite cathode – high body density semi-graphitic cathode carbon block
Aluminum electrolytic semi-graphitic cathode carbon block this project developed a high volume density semi-graphitic cathode carbon block. According to the domestic market demand, long-term market research on such products. This high technology products, production costs than the ordinary semi-graphitic cathode carbon block to increase, there will be a good market prospects. Research and development of high body density semi-graphitic cathode carbon block plays the role of the alternative can not be underestimated in the future development of national science and technology and other related products structural adjustment and development, led to the simultaneous development of related industries, driven by the same industry technological innovation and enhance the future development of related industries played an invaluable promoting and facilitating role.
Graphite cathode -high graphitic cathode carbon block and their production methods
The present invention relates to an aluminum reduction cell cathodes, especially high graphite cathodes and its production methods, the cathodes 15 and 30% of the particle size of less than 8 mm, 30-60% Electrically Calcined Anthracite the roasting broken,10-50% graphite and 15-25% asphalt. The high graphite cathodes production methods, including the ingredients, kneading, molding, baking. By this method to produce cathodes with high electrical conductivity, resistance to sodium corrosion resistance, mechanical strength and temperature resistance and good use of the cathode carbon block can effectively improve the service life of aluminum reduction cell.
Manufacturing method of the graphite cathode – natural graphite cathodes
An aluminum cell with graphite cathodes and its manufacturing method. The main feature is the use of natural graphite as the production cathodes aggregate, the method is unique in that the preparation of natural graphite aggregate. The products of the invention without graphitized cathode carbon block, the main technical indicators are more than ordinary and semi-graphitic cathode carbon block, close to or above the semi-graphite cathodes. Rational use of resources, saving energy use can reduce the cost of aluminum.

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.
Graphite cathode – Compare
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 .
