ABSTRACT:
The invention relates to a method of improving the current supply of electrolysis cells such as used in the production of aluminum by igneous electrolysis of alumina dissolved in cryolite, in which the cells are aligned in a lengthwise direction, allowing the harmful influence of the induced magnetic fields to be reduced.
In a series, each cell is supplied with current from the preceding cell both via the head and via at least one side riser. The output of the cathode bars are divided into two separate groups, the upstream group supplying the head of the subsequent cell and the downstream group supplying the side risers of the subsequent cell. This produces a substantial improvement in the efficiency and a greater regularity.
