<p><P>PROBLEM TO BE SOLVED: To provide a temperature control method and a temperature control device enabling highly accurate temperature control even in a heating process in which temperature measurement at desired accuracy by a thermometer cannot be expected due to low emissivity of a heating object such as a steel plate and modeling at desired accuracy is difficult. <P>SOLUTION: The temperature control device 5 includes: a required power computation model 10 for estimating an output value of a heater 3 from necessary temperature increase amountΔT of the steel plate 1 by model computation; a temperature FB control means 11 measuring a temperature of the steel plate 1 after heating by the heater 3 by a radiation thermometer 4 and calculating the output value of the heater 3 from a deviation between the measurement result and a temperature target value; and a correction means correcting a model computation value by a temperature FB control output value when output of the model computation value is instructed with respect to the heater 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
