Abstract

Disclosed is a cathode structure for reducing horizontal current in molten aluminum the structure comprising a cathode carbon block; the cathode carbon block is provided with a cathode steel bar thereunder; the cathode steel bar is provided with a separation gap in the longitudinal direction; the separation gap is provided with separation gap insulation materials therein; the bottom of the separation gap in the cathode steel bar together with the end and bottom of the cathode carbon block enclose an insulated rectangular area; the upper part of the cathode steel bar is connected to the cathode carbon block via an electric conductor. The structure homogenizes the current distribution of the molten aluminum in an aluminum electrolytic tank without changing the cathode discharge mode namely side discharge reduces the horizontal current in the molten aluminum improves electrolytic tank stability and enables the electrolytic tank to operate efficiently under a low polar distance thus effectively reducing the energy consumption per ton of aluminum saving energy while extending the service life of the cathode.
