Abstract

A cathode structure of an aluminum electrolytic cell, wherein the section of the cathode steel bar (2) adjacent to the end portion of the cathode carbon block (1) in its lengthwise direction is divided from top to bottom by partition gap(s) into at least two portions including an upper portion in a height direction of the cathode steel bar, the section of the cathode steel bar which is in a middle portion of the cathode carbon block and not divided is connected to the cathode carbon block (1) by totally using a conductor (6), the upper portion of the cathode steel bar (2) adjacent to the end portion of the cathode carbon block is connected to the cathode carbon block by using the conductor (6), the other portions below the upper portion are insulated from the cathode carbon block (1) by using an insulator (5), and the partition gap is filled with a partition gap insulating material (4). An aluminum electrolytic cell including the above-mentioned cathode structure and a process for reducing horizontal electric current in the liquid aluminum in the aluminum electrolytic cell are also disclosed. The present invention substantially reduces the horizontal electric current in the liquid aluminum, makes the cathode electric current more uniformly distributed, improves the stability of the electrolytic cell, prolongs the service lifetime of the electrolytic cell, effectively reduces energy consumption of producing aluminum per ton and exhibits a remarkable energy-saving effect.
