<p>Disclosed is a method for uniforming the distribution of current in an aluminum electrolysis cell. At least one cathode steel bar is fixedly tied or casted at the lower part of a cathode carbon block,and the cathode steel bar is cutted into several sections located at different places along the length direction by a separating seam.The said sections upon the separating seams of the cathode steel bar except those between the separating seams are totally connected with the cathode carbon block by conductive bodies,and the sections between and below the separating seams of the cathode carbon steel bar are insulated from the cathode carbon block by insulators. Insulating materials for separating seam are filled in the separating seam, so that the sections upon and below the separating seams of the cathode steel bar are insulated from each other,and one end of the cathode steel bar penetrates out of the electrolytic cell from its sidepiece. The cathode current of the aluminum electrolysis cell is distributed more uniformly, and the horizontal current in the aluminum liquid is reduced, then the stability of the electrolytic cell is improved, and the aluminum electrolysis cell can be efficiently circulated with a low polar distance, thus the energy consumption for per ton of aluminum is reduced effectively, and the energy-saving effect is achieved, meanwhile the service life of the cathode is also prolonged.</p> |
