Abstract
The trouble free operation of a continuous casting process utilizing a moving electromagnetic field for levitation requires information of sufficient accuracy concerning the position and extent of the solidification front inside the continuous casting die. The method and structure according to the invention for monitoring the solidification process employs signals from at least two sensor coils arranged concentrically around the continuous casting die. These signals are fed to a measuring transducer and processed in an appropriate manner. The configuration of the sensor coils inside the levitation coil generating the moving field is particularly preferred.
