Abstract

L'invention concerne des blocs cathodiques graphités permettant de produire de l'aluminium par réduction électrolytique d'oxyde d'aluminium dans un bain de cryolithe fondue. L'invention est caractérisée en ce que ces blocs cathodiques comportent sur leur longueur une résistance électrique profilée en forme de V, grossissant vers les extrémités et comportant au centre des blocs cathodiques une zone de discontinuité. L'invention se rapporte en outre à un procédé de production desdits blocs cathodiques et à leur utilisation dans le cadre de la production d'aluminium.
