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.
