Classification: CPC B | IPC B

Claim 9:
10. A breakout prediction device comprising:
an input unit configured to input a dimension of a solid product withdrawn from a mold in a continuous casting machine;
a plurality of thermometers embedded in the mold and configured to detect a temperature of the mold;
an interpolation processing execution unit configured to execute interpolation processing on the detected temperatures detected by the plurality of thermometers according to the dimension of the solid product;
a degree-of-deviation calculation unit configured to calculate, based on temperatures calculated by executing the interpolation processing, a component in a direction orthogonal to an influence coefficient vector obtained by principal component analysis as a degree of deviation from during a normal operation in which a breakout has not occurred; and
a breakout prediction unit configured to predict a breakout based on the degree of deviation.
