Arrangement for compensating detrimental magnetic influence between two or more rows of longitudinally oriented electrolytic reduction cells, for aluminum

摘要

Arrangement is disclosed for compensating detrimental magnetic influence on longitudinally oriented pots (U3) in a pot row, from the current in one or more adjacent pot rows, in plants for producing metal, for example aluminum, by electrolytic reduction of a molten bath. Two substantially symmetrical groups (k31, k32) of cathode taps located at opposite sides of the positive end of the pot, are each connected to a separate compensation bus bar (X, Y) so located in relation to the pot (U3) that they form a current loop around the cathode in a clockwise or in a counter-clockwise direction, depending upon whether a positive or a negative vertical magnetic field is to be compensated for.
