In recent years,the graphitized cathode carbon block has been favored by electrolytic aluminum industry because of its excellent properties.However,some enterprises only changed the lining material of the cathode and other parts,and the magnetic field and bus configuration were not adjusted,thus resulting in a mismatch in the energy balance of the electrolytic cell,as well as the phenomenon of the electrolytic cell being cold and extending the ledge,which seriously affected the normal production of the electrolytic cell.In this paper,the measure of steel bar insulation for the fully-graphitized cathode electrolytic cell is adopted to effectively reduce the heat dissipation of the electrolytic cell.Through comparative analysis of the temperature,effect coefficient and voltage difference before and after the steel bar insulation,it is effectively proved that the measure is effective,thus finally achieving the purpose of energy balance of the electrolytic cell.
