Abstract
This aluminum smelter comprises a row of cells () arranged transversely in relation to the length of the row, the cells () individually comprising an anode (), rising and connecting electrical conductors () running upwards along the two opposite longitudinal edges of the cell () to route the electrolysis current towards the anode (), and a cathode () through which pass cathode conductors () connected to cathode outputs connected to linking conductors to route the electrolysis current to the rising and connecting electrical conductors of the next cell (). Furthermore the aluminum smelter comprises a compensating electrical circuit separate from the electrical circuit through which the electrolysis current flows, running beneath the cells (), through which a compensating current may flow beneath the cells () in a direction opposite to the overall direction of flow of the electrolysis current.
