Modeling Cathode Assembly over its Lifetime Considering Creeping, Diffusion, Erosion
Description
Canada is one of the largest producers of aluminum in the world. In fact, aluminium production is one of the main industries in Quebec. In electrolysis cells, a strong current passes between the anodes and the cathodes. The cathode assembly is made of a carbon block and steel bars. About 10% of the energy losses occur in the cathode. Moreover, the cathode erodes over time, which is one of the main causes leading to the end of life of a cell. In this project, we want to develop a 3D thermo-electro-mechanical (TEM) finite element model to simulate the whole life of a cathode and optimize its design. In addition, experimental tests will allow to characterize the behavior of materials at high temperatures, such as those found in practice in the smelter. In the end, the project will help to enhance the energy performance and the lifetime of electrolytic cells.

Research Environment
REGAL - Aluminium Research Centre, Université Laval
Université Laval is a pole of expertise on the primary production of aluminum, involving many professors, research assistants and students who are members of REGAL (https://www.regal-aluminium.ca/fr/accueil/). In close partnership with the industry, our dynamic team aims to better understand and to improve the various processes used in smelters through experimental work, modeling and data processing.
