Device and method for connecting inert anodes for the production of aluminium by fused-salt electrolysis
First Claim
1. Anode assembly (1) to be used in a fused bath electrolysis aluminium production cell, comprising:
- at least one inert anode (2) in the shape of a ladle, with length L, comprising a cavity (21), an open end (22) comprising an opening (200), a wall (23) surrounding the cavity (21), a closed end (24) and at least one mechanical connection means (26, 27, 28, 29);
at least one connection conductor (3, 4, 4′
, 5) comprising a connection end (42) and at least one mechanical connection (44, 45, 46) capable of cooperating with the mechanical connection means (26, 27, 28, 29) of the anode (2) so as to set up a mechanical link between the conductor and the anode;
at least one brazed metallic joint (31) or at least one brazing material that could form a brazed metallic joint (31) by brazing wholly or partly during use, the said joint (31) being located between all or part of at least one surface (20, 20′
, 20″
) of the open end (22) of the anode (2) and all or part of at least one surface (40, 40′
, 40″
) of the connection end (42) of the conductor (3, 4, 4′
, 5).

Abstract
This invention relates to an anode assembly (1) to be used in a fused bath electrolysis aluminium production cell. This assembly comprises one inert anode (2) in the shape of a ladle, one connection conductor (3, 4, 5), mechanical connection means capable of cooperating so as to set up a mechanical link between the conductor and the anode, one metallic joint (31) that is or could be formed by brazing being located between all or part of at least one surface (20, 20′, 20″) of the open end (22) of the anode (2) and all or part of at least one surface (40, 40′, 40″) of the connection end (42) of the conductor (3, 4, 5). The invention simplifies manufacturing of anode assemblies comprising one inert anode.
