This article examines different reasons for the occurrence of anode effects (AEs) in the electrolytic production of aluminum. Numerous attempts made to eliminate AEs by shifting the anode relative to the transverse horizontal axis of the cell were unsuccessful. Substantiation is provided and laboratory proof given for the theory that anode effects are of a gas-hydrodynamic nature and are related to the stability of the foam structures formed in the gas-liquid near-anode layer.

Keywords
