Abstract

A method of predicting a breakout of the present invention includes: a step of receiving input of a dimension of a cast strand to be pulled out from a mold included in a continuous casting machine; a step of detecting temperatures of the mold with a plurality of thermometers buried in the mold; a step of executing interpolation processing in accordance with a dimension of the cast strand on detected temperatures detected by the plurality of thermometers; a step of calculating temperature change amounts by comparison with temperatures before a first period; a step of acquiring a standard deviation of temperature change amounts of the thermometers in a second period; a step of standardizing temperature changes by dividing the temperature change amounts by the standard deviation; a step of calculating a component in a direction orthogonal to an influence coefficient vector obtained by principal component analysis, as a deviation degree from a normal operation time when no breakout occurs, based on a temperature change amount calculated by executing the interpolation processing; and a step of predicting the breakout based on the deviation degree.
