The invention relates to an anode assembly (1) for a cell used to produce aluminium by fused-salt electrolysis. The assembly comprises an inert anode (2) in the form of a pocket, a connecting conductor (3, 4, 5), mechanical connection means which can cooperate in order to establish a mechanical link between the conductor and the anode, and a soldered metal joint or a metal joint which can be formed by soldering (31) and which is arranged either between all or part of at least one surface (20, 20, 20') of the open extremity (22) of the anode (2) and all or part of at least one surface (40, 40', 40") of the extremity of the connection (42) of the conductor (3, 4, 5). The invention makes it possible to simplify the production of anode assemblies comprising an inert anode.
L'invention a pour objet un assemblage anodique (1) destiné à une cellule de production d'aluminium par électrolyse ignée. Cet assemblage comprend une anode inerte (2) en forme de poche, un conducteur de raccordement (3, 4, 5), des moyens de raccordement mécanique aptes à coopérer de manière à établir une liaison mécanique" entre le conducteur et l'anode, et un joint métallique brasé, ou susceptible d'être formé par brasage, (31) situé entre tout ou partie d'au moins une surface (20, 20, 20') de l'extrémité ouverte (22) de l'anode (2) et tout ou partie d'au moins une surface (40, 40', 40") de l'extrémité de raccordement (42) du conducteur (3, 4, 5). L'invention permet de simplifier la fabrication des assemblages anodiques comportant une anode inerte.
