ABSTRACT:
Process for early detection of an anode effect in an aluminum production cell based on molten salt electrolysis. The cell comprises at least one anode, at least one cathode and cathode connecting conductors and anode connecting conductors. The process comprises:measurement of a first electrical voltage signal U1between a first cathode measurement point on a cathode connecting conductor and a first anode measurement point on an anode connecting conductor;measurement of at least one second electrical voltage signal U2between a second cathode measurement point on a cathode connecting conductor and a second anode measurement point on an anode connecting conductor, at least one of these second measurement points being distinct from the first measurement points;determination of the value of at least one signal comparison function F over a determined time period T;determination of the value of at least one risk indicator A identifying the risk of occurrence of an anode effect, starting from the comparison function.
