  • Method for non-destructively examining an anode of an aluminium electrolysis cell
    Patent number: 11630081
    Abstract: The method for non-destructive flaw detection of aluminium reduction cell anodes is claimed, including the building of a computed model of an anode or the use of a specified model with the known data on the geometry and specific resistance of the anode, the geometry and coordinates of internal defects, wherein several cyclic calculations are carried out; the results of calculations are represented in the form of a 3D-matrix of amplitudes and directions of vectors of calculated intensities or inductions of the electromagnetic field at the discretization points near the outer surface of the anode; at least a pair of electrically conductive contacts that supply the specified amount of electrical current through the anode are placed on the outer surfaces of the inspected anode; at least one sensor is placed near the outer surface of the inspected anode, and the amplitude and direction of the magnetic field intensity or induction vectors are measured and represented as a 3D-matrix of measured magnetic field intens
