Abstract
A process for monitoring continuous casting molds is presented. A primary coil coaxially surrounding the continuous casting mold is powered with currents whose Fourier analysis includes several frequencies. Several secondary coils are also arranged coaxially between the primary coil and the mold and surround the mold. The secondary coils are placed around the liquid metal pool level region, with the secondary coil in the lowest location being located beneath the pool surface at all times and serving as a reference coil. The differences between the Fourier components of the signals measured on the various secondary coils and the reference coil are taken, related to the intensities in the primary coil, and analyzed by magnitude or phase. By comparison of the various signals, the presence of liquid metal or slag, the temperature prevailing in the particular region of the mold wall, are determined.
