The present invention discloses one kind of lateral inside lining for aluminum electrolytic bath and the application of waste cathode in making the lateral inside lining. The lateral inside lining consists of prefabricated blocks in irregular shapes, and the prefabricated blocks may be made with waste cathode carbon block. The prefabricated block has stable quality, no delamination, high strength, high erosion resistance and no pollution. The lateral inside lining of waste cathode carbon block has high specific resistance, high heat conductivity, capacity of forming lateral guard of aluminum electrolytic bath and prolonging the service life of aluminum electrolytic bath and environment friendship. |
