Study on Optimization of Anode Structure for Aluminum Reduction Cell

Abstract

Different top surface anode structures have been studied based on the multi-physics coupling simulation software of ANSYS. The influences on current distribution, temperature distribution, thermal stress distribution and anode voltage drop were compared with different top surface structures, such as the angular, arc, right angle, wave and other top surface structures, which the main purpose is to achieve lower anode gross consumption ultimately. The simulation results showed that the top surface structure with the wave is the best in the distribution of above related parameters, and the anode gross consumption is the lowest.
