✦ Synopsis
Electrical power accounts for the largest part of the primary aluminum production cost, hence smelters strive to improve their overall e$ciency. Current Hall}HeH roult reduction cell technology generally uses cast iron to connect steel conductors to carbon electrodes. In this paper, the reduction of anodic connector electrical losses was investigated through a combination of simple experiments and weakly coupled thermoelectro-mechanical "nite element models. A novel phenomenological constitutive model was used to predict the electrical contact resistance at the cast iron to carbon interface. Parametric design studies were carried, and substantial savings are expected from the optimization of the anodic connector geometry.
