Abstract: This invention refers to metallurgy of aluminum, specifically, to the method of extracting aluminum by molten salt reduction, namely, the method of controlling an aluminum reduction cell by the minimum power. This method consists in measuring the resistive voltage drop in the reduction cell, comparison of the measured value with the set voltage drop value in the reduction cell and elimination of the mismatch by the relevant anode displacement. The anode displacement reduces the mismatch between the heating power and the set value until the minimum power is released in the reduction cell. Release of the minimum power is determined by the spontaneous growth of the electrochemical component of the reduction cell voltage, this mismatch is maintained with the relevant anode displacement without any variations in the thermal state of the reduction cell. The invention enables to reduce the electric power consumption, enhance the current metal yield and reduce the labor intensity of reduction cell maintenance.
