The erosion rate of cathode panels in aluminum reduction cells is significantly influenced by current density, leading to accelerated erosion in areas of higher current density. This study presents a novel 3D transient thermo-electric erosion model designed to analyze and predict the cathode panel erosion evolution over time, ultimately enabling the comparison of various cathode lining designs and their expected pot life. Utilizing the commercial finite element code ANSYS®, the model incorporates an erosion law that calculates erosion rates based on surface current density, facilitating the precise simulation of cathode performance under operational conditions. Results from this model indicate the potential for innovative design changes that could significantly extend the operational lifetime of high amperage cells equipped with graphitized cathode blocks, showing as much as a doubling of theoretical maximum cell life. This research aims to contribute to the optimization of cathode designs in aluminum reduction processes, addressing the critical challenges posed by erosion and resistance increases as cells age.
