[0002] Aluminum electrolysis cells are a key piece of industrial equipment used in aluminum production. They produce aluminum metal by electrolyzing a mixture of alumina and cryolite. During the electrolysis process, an electric current flows through a molten electrolyte between a cathode and an anode, causing aluminum ions to precipitate at the cathode and oxygen to be released at the anode. In actual production, welding, assembly, and repair of certain modules within the aluminum electrolysis cell are labor-intensive and resource-intensive.
