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. An alarm producing unit produces an alarm when one of outputs of the at least three breakout detection networks exceeds a predetermined threshold level.
