TEMPERATURE MEASURING DEVICE, HEATER FOR PLATING STEEL PLATE, PRESSING DEVICE FOR PLATING STEEL PLATE, METHOD FOR HEATING PLATING STEEL PLATE, AND METHOD FOR PRESSING PLATING STEEL PLATE

摘要

PROBLEM TO BE SOLVED: To provide a temperature measuring device that can measure the temperature of a plating steel plate while suppressing influence due to variations in the emissivity of the plating steel plate at heating.SOLUTION: A temperature measuring device 4 includes: a reflecting member 6 facing a surface 1a of a plating steel plate 1 and having a reflecting surface 61 reflecting a light emitted from the plating steel plate and an opening 62 in the reflecting surface; and detection means 7 detecting the temperature of the plating steel plate based on the amount of light having entered the opening from the direction of the plating steel plate.SELECTED DRAWING: Figure 2
