Abstract
Methods and apparatus for inspecting metallurgical furnace walls. A method may comprise receiving a plurality of time domain signals from one or more sensors generated by a reflected stress wave induced by an impactor impacting the metallurgical vessel wall at a predetermined distance from an impact point, converting the plurality of time domain signals into a plurality of frequency domain signals and identifying peaks therein, generating a combined frequency domain signal by cancelling out any peak from one of the plurality of frequency domain signals not having a corresponding peak in at least one other of the plurality of frequency domain signals, and determining at least one of a thickness of the metallurgical vessel wall or an estimated location of a defect in the metallurgical vessel wall based on the combined frequency domain signal.
