Abstract

Procedure for the electrolytic production of metals, particularly aluminum from Al2 O3 dissolved in fluorinated molten baths, and with consumable anodes in furnaces with vertical or inclined electrodes, characterized in that the anode restoration is carried out by continuously sliding the members or restoration materials by by means of a pressure exerted from the top, along a plane that forms an acute angle with respect to the plane of the anode face on which the electrolytic consumption of said anode material takes place, while maintaining the inter-electrode spacing automatically constant with the help of means to absorb excess pressure.
