ABSTRACT:
In an aluminum electrolysis furnace provided with an anode structure located above a cathode forming part of the bottom of the furnace chamber, whereby direct electric current between the anode and the cathode causes aluminum to be obtained from aluminum oxide, a portion of the surface of the cathode facing the anode is covered with an electrically nonconductive material to create an electric current distribution which tends to improve the heat distribution within the furnace chamber.
