Classification: CPC B | IPC B

Claim 0:
1. A breakout prediction method comprising:
a step of inputting a dimension of a solid product withdrawn from a mold in a continuous casting machine;
a step of detecting a temperature of the mold by a plurality of thermometers embedded in the mold;
a step of executing interpolation processing on the detected temperatures detected by the plurality of thermometers according to the dimension of the solid product;
a step of calculating, 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 step of predicting a breakout based on the degree of deviation.
