Abstract: In a breakout prediction system for predicting breakout in a mold of a continuous casting machine, a prediction deciding section is connected to one of temperature sensors located on the mold and at least three temperature sensors which are adjacent to the one of the temperature sensors. In the prediction deciding section, at least three cross-correlators are connected to the one of the temperature sensors and the at least three temperature sensors and carry out a predetermined normalization operation to produce operation results. A temperature variation pattern detector is connected to the one of the temperature sensors to detect a temperature variation pattern. At least three peak detectors are connected to the at least three cross-correlators, respectively, to detect peak values of the operation results. At least three breakout detection networks are supplied with the peak values and the temperature variation pattern to carry out decision on breakout prediction.

Abstract: In a mold oscillation device for making oscillation of a mold used in a continuous casting machine, an acceleration sensor (22) detects the oscillation to produce an oscillation detection signal representative of said oscillation. The oscillation detection signal has a particular waveform. Responsive to the oscillation detection signal, a signal producing circuit (30) produces an adjusting signal with reference to the particular waveform. With reference to the adjusting signal, a control unit (16) controls the oscillation. In order to produce the adjusting signal, it is preferable that the signal producing circuit carries out a frequency analysis as regards the particular waveform.
