  • Technique for automatic quenching of anode effects in aluminium reduction cells
    Patent number: 4230540
    Abstract: For the clearance of anode effects in operation of electrolytic cells for aluminium production, movement in the metal pool is induced to effect short-circuiting of the cell and disturbance of any gas film on the face of the anode(s) by raising the anode(s) and then lowering them to datum position and/or tilting the anode in relation to datum position. Upward movement is terminated either after a predetermined distance or when a predetermined cell voltage is attained. Fresh alumina is introduced into the cell by breaking alumina crust by anode movement or by independent supply.
