This cell () comprises a pot shell () having two longitudinal sides () which are symmetrical in relation to a longitudinal median plane (P) of the electrolytic cell (), an anode assembly which can only move in vertical translation with respect to the pot shell (), the anode assembly comprising an anode block () and a transverse anode support () extending at right angles to the longitudinal sides () of the pot shell (), from which support the anode block () is suspended. The anode support () comprises two connecting portions () from which electrolysis current is supplied to the anode support (), and the cell () comprises electrical connection conductors () electrically connected to the two connecting portions () of the anode support (), the two connecting portions () being located on either side of the plane (P).

Electrolytic cell intended for the production of aluminium and electrolytic smelter comprising this cell

The present invention relates to a manufacturing process for an anode assembly intended for cells for the production of aluminum by electrolysis, the anode assembly being of the type having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member, the method comprising a formation phase of at least one sealed area filled with sealing material and at least one unsealed area devoid of sealing material, said at least one unsealed area extending to one of the longitudinal ends of the longitudinal member.

Anode assembly and associated production method

Anode assembly () comprising an anode () and an anode support () for the production of aluminum, characterized in that the anode assembly () comprises an electrical connecting element () to electrically connect the anode support () with the anode (), and at least one thermally insulating element () arranged to reduce heat transfer between the anode () and the anode support () during the production of aluminum.

Anode assembly

An electrolytic cell is suitable for production of aluminium, and includes at least one collector bar made of first metal and at least one complementary bar made of a second metal having an electrical conductivity greater than the first metal and arranged adjacent to one of the side faces of the collector bar so that the external end of the complementary bar is at a specified distance from a specified end face of the block. The second end terminates so as to limit heat losses from said cell. The cell makes it possible to obtain significantly lower voltage drops while avoiding excessive heat losses through the collector bars.
