[0002] Cathode carbon blocks are mainly concentrated in the aluminum electrolysis industry and are widely used in aluminum smelting pot electrolytic cells, and are important components in the aluminum electrolytic cell. The cathode carbon blocks are installed at the bottom of the electrolytic cell. The main function of the cathode carbon blocks is to conduct electricity, and together with the anode carbon blocks, they form an electrolytic cell in the electrolysis process, so that the electric current can pass through the electrolyte, thereby realizing the electrolytic extraction of aluminum. The cathode carbon blocks are usually made of high-purity carbon materials and have good electrical conductivity, corrosion resistance and mechanical strength. During the production of cathode carbon blocks, the cathode carbon blocks need to be turned over.
