Abstract
La présente invention concerne un ensemble cathode pour une cellule d'électrolyse de type Hall-Heroult pour la production d'aluminium, qui comprend un bloc de cathode fiché ou connecté à des barres de collecteur d'acier, des tiges de Cu ou une plaque de collecteur métallique, la surface de bloc de cathode comprend en partie un matériau composite résistant à l'usure de sorte que le bloc de cathode peut être conçu avec une hauteur inférieure, ce qui peut avoir de nombreux avantages. La présente invention concerne également un procédé de production de l'ensemble cathode.
