Abstract
L'invention fournit un ensemble cathode qui permet de faciliter une opération de connexion entre un bloc cathodique et des barres collectrices. Cet ensemble cathode (100) est mis en ?uvre dans un four électrolytique pour fusion d'aluminium, et est équipé d'un bloc cathodique (10) en carbone dans lequel est agencée une rainure (10a), et d'une unité de barres collectrices (20) insérée dans la rainure (10a). L'unité de barres collectrices (20) contient : deux barres collectrices (21, 22) en métal qui présentent chacune une forme se prolongeant dans la même direction que la rainure (10a), et qui sont disposées rangées dans la direction largeur de la rainure (10a) ; et un élément ajustement d'intervalle (23) ajustant l'intervalle entre les deux barres collectrices (21, 22). L'élément ajustement d'intervalle (23) contient un mécanisme ajustant l'intervalle entre les deux barres collectrices (21, 22) au moyen d'une vis.
