Abstract (en)

[origin: EP0384174A2] For trouble-free progress of the casting process in continuous casting, as accurate data as possible on the position and extent of the solidification front within the continuous casting mould surrounded by an electromagnetic moving field are required. <??>The method according to the invention for monitoring the solidification process uses the signals of at least two sensor coils arranged concentrically around the continuous casting mould. The signals are fed to a measuring transducer and processed in an appropriate manner. The arrangement of the sensor coils within the levitation coil generating the moving field is particularly preferred.
