PROBLEM TO BE SOLVED: To provide a method for measuring a workpiece temperature that can accurately measure change in temperatures of a heated workpiece during cooling of the workpiece, without fixing a thermocouple to the workpiece.SOLUTION: There is provided a method for measuring the temperature of a workpiece heated in a workpiece heating step and then cooled in a cooling room (including a naturally cooling room), which can obtain a measurement value close to an actual temperature by measuring the temperature of the workpiece heated and then put into the cooling room, with a two-color radiation thermometer.SELECTED DRAWING: None |
