Abstract

L'invention a pour objets un procédé et un dispositif de détection des effets d'anode dans une cellule de production d'aluminium par électrolyse en sel fondu, dans lesquels on mesure au moins un premier signal de tension électrique U1 et un deuxième signal de tension électrique U2 à deux endroits distincts de ladite cellule, et dans lesquels on détermine la valeur d'au moins un indicateur anticipé d'effet d'anode A à partir d'une comparaison desdits signaux U1 et U2. L'invention permet une détection simple, fiable et précoce des effets d'anode.
