ABSTRACT:
The energy balance in an aluminum reduction cell is controlled by measuring the temperature of the side lining of the cell, preferably at the level of the surface of the electrolyte, comparing the measured temperature with a reference temperature, and when the difference between the measured and reference temperatures exceeds a given value adjusting the depth of immersion of the cell anodes within the electrolyte.
