| Cathode carbon block is a carbon block made of high-quality anthracite, coke, graphite, etc. as raw materials. Used as a cathode for aluminum electrolysis cells. Including the bottom carbon block, the side carbon block, the tamping carbon paste or carbon glue connecting the carbon block, and the cathode steel rod, etc. Type 1. Bottom carbon block It plays a dual role of conducting electricity and forming the lining of the electrolytic cell. It is built at the bottom of the electrolytic cell, and the exterior is built with refractory materials and reinforced with steel shells. It can be divided into ordinary cathode carbon block, semi-graphite cathode carbon block and graphite cathode carbon block. 2. Side carbon block It is used to build the side part of the aluminum electrolytic cell to form the main body of the side lining of the electrolytic cell. It can be divided into ordinary side carbon block and semi-graphite side carbon block, and the production method is similar to the bottom carbon block. With the promotion and application of silicon nitride combined with carbonized silicon blocks on the side of aluminum electrolytic cells, the amount of carbon blocks on the side has been reduced. 3. Cathode steel rod The product that connects the cathode carbon block and the cathode busbar in the aluminum electrolytic cell to form the cathode circuit of the aluminum electrolytic cell. It is divided into single rod assembly (that is, a cathode carbon block is assembled with one cathode steel rod) and double rod assembly (that is, two cathode steel rods are assembled at the end of a cathode carbon block). |
