In the aluminium industry the anode quality is an important factor that influences the Hall-Heroult process efficiency. For this purpose, many efforts have been done in order to optimize the anode design such as the use of slots which allow gases, generated through the reduction operation, to escape. The aim of this work is to investigate the effect of the slots size on the thermo-electrical behaviour of the anode. To this end, a 3D thermo-electrical model taking into account the anode, the bath and the anode connector has been developed using Ansys software. Material parameters such as electrical resistivity, thermal conductivity and electrical contact resistance are temperature dependent. Numerical simulations were performed for several slots thicknesses. Furthermore, a new design based on a variable slots thickness is simulated.
