Abstract Scope Preheating of electrolysis cell using coke bed is a delicate process, which has a significant impact on the cell life. A successful preheating is considered by many factors such as: the final cathode surface temperature, the heat-up rate, the anodic current distribution and the temperature distribution (to reduce the risk of damage of the cathode/lining materials). Therefore, a better understanding of the cell behaviour is required to optimize this critical phase. In this work, electrical, thermal and displacement data have been measured on a cell during its preheating. Those measurements were then used to calibrate a ¼ cell model developed using ANSYS™, including a transient thermo-electro-mechanical weakly coupled analysis. The results obtained are in agreement with in situ measurements and allow a better understanding of the anodic current distribution, cathode surface temperature, baking level of ramming paste and stress distribution in the cathode/lining, which are critical information for further optimization.
