Abstract
The system () and the method are used for forecasting the electrical conductivity of an anode () for aluminum production before the anode () is baked. In the system (), at least one receiving coil () is coupled to an electromagnetic field emitting unit (). A sensing device () is connected to the receiving coil (), the sensing device () outputting a signal indicative of a variation of the electromagnetic field received by the receiving coil () as the crude anode (), or a portion thereof, passes inside the receiving coil (). A value indicative of the electrical conductivity of the anode () is then calculated using the signal from the sensing device () and signals previously obtained using reference anodes (). This way, the electrical conductivity of the anodes () can be forecasted before the crude anodes () are baked.
