Abstract
Method and apparatus for controlling the temperature of a molten salt, electrolytic demagging cell wherein an operating condition of the cell (e.g., current, temperature, etc.) is measured and a cathode immersed in the cell's electrolyte is moved to and fro the aluminum melt in the cell in response to the measured condition to vary the heat input to the cell.
