Calculation of Magnetic Field of the 168 kA Aluminum Reduction Cell with ANSYS

The magnetic field of the 168 kA aluminum reduction cell was calculated with the software ANSYS in our study. The calculated results showed that the magnetic line of the aluminum and electrolyte in cell formed a clockwise swirl. The X and Z magnetic intensity of aluminum was similar with the antisymmetric distribution and the magnetic intensity vector of aluminum reduced along the -Z axis. The X, Y and Z magnetic intensity in the electrolyte under the anode bottom was similar with the antisymmetric distribution along short axis (Y axis), long axis (X axis) and short axis (Y axis), respectively. The magnetic intensity vector of electrolyte in the gap of the anode was higher than that under the anode bottom. The X and Z magnetic intensity in the interface of melt was also similar with the antisymmetric distribution. The numerical simulations with ANSYS have the important references for project analysis and diagnose.
