Modeling of Vibro-compaction to Understand How It Affects Green Anode Density


Canada is one of the main producers of aluminum in the world and the majority of the production is made in Quebec. In electrolytic cells, a strong current flows between the anodes and the cathodes. Since the anodes are consumed by the electrolysis, they must be constantly replaced in the pots. For this reason, many aluminium smelters continuously produce new anodes. The quality of the anodes produced has a crucial impact on the performance of the electrolysis process. One of the important steps in the production of anodes is the vibro-compaction of the anode paste in a mold to form green anodes and the way this is done greatly affects the density distribution. A rheological model will be developed for high vibro-compaction frequencies and different anode paste recipes. The model will be calibrated using experimental data. Ultimately, the model will be used to simulate the vibro-compaction process to optimize the uniformity of the density distribution. Obtaining better anodes will help to improve the energy performance and reduce GHG emissions from the electrolytic cells.
