Abstract

L'invention a pour objet un élément cathodique, pour l'équipement d'une cuve de cellule d'électrolyse destinée à la production d'aluminium, comportant un bloc cathodique (5) en matériau carboné ayant au moins une rainure longitudinale sur une de ces faces latérales et une barre de raccordement (6) en acier, qui est logée dans ladite rainure de façon à ce qu'une partie de la barre émerge d'une extrémité du bloc, qui est scellée dans la rainure par interposition d'un matériau de scellement conducteur entre la barre et le bloc et qui contient au moins un insert métallique dont la conductivité électrique est supérieure à celle dudit acier. Selon l'invention, l'insert (16) est disposé longitudinalement à l'intérieur de la barre et se situe, au moins en partie, dans le tronçon (19) de la barre de raccordement qui est destiné à se situer à l'extérieur de la cuve et la barre de raccordement (6) n'est pas scellée au bloc cathodique dans une zone de non-scellement (17) de surface déterminée S située à l'extrémité de la rainure en tête de bloc. La présence d'un insert selon l'invention permet d'obtenir simultanément une très forte réduction de la chute de tension cathodique globale et de la densité de courant en tête de bloc.
