Product Descriptions
Cathode carbon block is the main component of the cathode structure of aluminum electrolytic cell. It not only plays the role of cathode conductor in aluminum electrolysis production, but also serves as the lining material of electrolytic cell. The quality of cathode carbon block directly affects the service life and power consumption of electrolytic cell.
Our company has been producing cathode carbon bricks for aluminum for 30 years, producing graphitized, high-graphitic and semi-graphitic cathode carbon blocks for aluminum electrolysis. The high quality of the product benefits from the local high-quality Taixi anthracite raw materials, using high-quality electric calcined anthracite, artificial graphite and petroleum coke, etc., through kneading, molding, roasting, impregnation, graphitization, and machining. It has the advantages of low resistivity, good thermal conductivity, low thermal expansion rate, low sodium expansion rate, high sodium corrosion resistance and high thermal shock resistance, which can prolong the service life of electrolytic cell and make due contributions to the continuous improvement of domestic aluminum electrolysis technology level.
