Abstract

L'invention concerne un bloc cathodique pour une cellule d'électrolyse de l'aluminium à base de carbone et/ou de graphite. Le bloc cathodique présente au moins une rainure s'étendant dans la direction longitudinale du bloc cathodique. Au moins une des rainures présente une profondeur variable, vue sur toute la longueur du bloc cathodique, et au moins une barre conductrice est disposée dans la ou les rainures. L'espace intermédiaire entre la ou les barres conductrices et la paroi délimitant la ou les rainures d'une profondeur variable est rempli au moins en partie d'acier.
