摘要

Aluminum extraction has a very high energy consumption process, so reducing energy consumption is one of the most important roles in aluminum reduction cell design. The good path to achieve this goal can be made by voltage savings at the anode assembly. The aim of this work is todevelop3D thermo-electrical finite element model and validate based on actual temperature measurements and electrical calculations for the anode assembly. The model is used to estimate the temperature distribution and the anodic voltage drop over the anode assembly and to suggest alternative design modifications to reduce the anodic voltage drop. The effect of changing in stub diameter and chemical composition of cast iron on anodic voltage drop were studied. The findings indicated that the effect of stub diameter is more effective as compare with the changing in cast iron composition.
