Abstract

L'invention concerne un procédé de production de blocs cathodiques graphités. Un procédé de graphitisation longitudinale fait appel à un bloc cathodique carbonisé dont la section transversale aux extrémités du bloc est plus grande que celle au milieu, au moins une partie de la matière graphitée étant supprimée aux extrémités une fois le processus de graphitisation achevé. L'invention se rapporte en outre aux blocs cathodiques produits selon ledit procédé et à leur utilisation dans le cadre de la production électrolytique d'aluminium.
