Series of electrolysis cells for the production of aluminium comprising means for balancing of the fields in a queue magnetic

摘要

P the invention relates to a series (1) of electrolytic cells intended for the production of aluminium by fused bath electrolysis, which comprises at least two rows of cells disposed transversely, a correction circuit inside (200) comprising, for each row, at least one conductor of the inside (20, 20 ') of the side of the neighboring line, and a main connection circuit (400) between the end cells (101, 101 ′) of the strings. For at least one line, the main connection circuit (400) comprises a sheet of conductors, each conductor extends from the edge of the cell of the end of the line to a determined distance d2, d2 'that - latter, and the correction circuit inside (200) comprises a transverse section of the conductor which is situated at a determined distance d1, d1' of the cell of the end (101, 101 ′) and runs along the cell of the end on a determined portion of its length lo. The present invention makes it possible to reduce the vertical field, the additional means to very low values for the electrolysis current whose intensity is higher than 300 ka. / p
