Characterization of the mechanical behaviro of anode paste during vibrocompaction

Description

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. The anodes must be constantly replaced as they are consumed in the process. To produce the anodes, an anode paste is obtained by mixing coke, pitch and anode butts. The paste is then vibrocompacted in a mold. Vibrocompaction causes density gradients in the anode which can negatively affect its performance in the cells. In this project, we aim to better understand the mechanical behavior of the anode paste during vibrocompaction, especially at high frequency. Laboratory tests will be conducted for this purpose by the student. The data obtained will allow the team to develop new models taking into account the impact of frequency, wall friction and the anode paste recipe, among others. Ultimately, the project will improve the quality of the anodes and thus reduce the energy and raw material consumption of aluminum smelters.
