| Abstract Scope |
The inability of the new anode to conduct electricity initially poses a significant challenge to the stability of the cell during the anode change process. In this study, a computer simulation model was developed to analyze horizontal currents in liquid metal and metal-bath interface deformation before and after change. Our findings reveal that post-change, the maximum horizontal current can surge 3 to 4 times compared to pre-change levels. Additionally, the metal-bath interface deformation amplitude increases by 4 to 10 mm, with areas exceeding 10 mm and 20 mm deformations increasing by 1.5 and 2.3 times respectively. An anode current monitoring system installed on the pot captured significant changes in current magnitude, fluctuation, and recovery speed following anode change. Integrating these empirical observations with simulation results, we offer explanations for current magnitude and fluctuation changes and propose strategies to expedite current recovery, vital for maintaining electrolytic cell stability during anode replacements. |
