Study on the Inter-Electrode Process of Aluminum Electrolysis (Ⅱ)—Digital Analysis of the Anode Gas Distribution Patterns on the Anode Surface Using A See-Through Cell

The evolution behavior of anode gas during aluminum electrolysis has been a hot spot research for energy saving and process control. In the present work, bubble was investigated using lab-scale see-though cell. characters on an 11 cm2 (bottom surface area) flat anode, slotted 50 were with statistical analysis, respectively. results showed that bubbles tended to generate adhere certain regions due heterogeneity carbon material, adhering moved when current density increased. slot lowered actual significantly by reducing coverage. Influenced group effect bubbles, constituted lower coverage rate, average size, than anode.
