Abstract: The aluminum industry faces economical headwinds, thus needing to reduce its operating costs. The project studies specifically energy losses at anode sealing location. Experiments were conducted from room conditions up to the maximum capacity of the bench test. Laboratory work was completed using tri-material samples (made in such a way to replicate accurately reality) and an innovative bench test using magnetic induction as a source of heat that enables minimal heat-up time and sample oxidation during experiments. Non-linear regression was then used to retrieve a model from laboratory results. Analysis showed that a power model represents accurately the interfaces behavior from room to operation conditions. Comparison with literature showed that the order of magnitude is the same but results are not similar. This observation can be explained by the use of slightly different materials and also due to the use of a different experimental procedure.
