It has been previously demonstrated [1,2] that using selective collector bar rodding
has a big impact on the uniformity of the current density at the top surface of the cathode
block and hence on the intensity of the horizontal current in the metal pad.
The present study investigates the impact of using selective collector bar rodding on
the MHD stability of a 500 kA aluminium electrolysis cell. For this purpose the recently
developed MHD package for the aluminium reduction cell time dependent behavior is used.
