Numerical simulation of electro-thermal field in a large-scale aluminum reduction cell with graphitized cathode

摘要

The methods of industrial test and numerical simulation were utilized to study the electro-thermal fields of 300kA aluminum electrolysis cell with graphitized cathode, a custom code was developed to model the coupled physic fields based on the commercial code ANSYS, and the calculated result has been compared and discussed with the measurements. It is shown the temperature gradient in the graphitized cathode is lower than that of ordinary cathode and the cell will show better performance when combined with side lining of SiC materials.
