定するようになっている。The temperature measuring device 3 shown in FIG. 2 is applied to a gutter through which molten steel flows. Reference numeral 41 in the figure indicates a gutter, and this gutter 4
Molten copper 42 is flowing through I. A cover 43 is provided on both sides of the gutter 41, and a burner 44 is provided passing through the cover 43. The burner 44 is used to heat the molten copper. In such a configuration, the cover 43 is provided with an optical path securing tube (cylindrical body) 31. This optical path securing tube 3I
is provided to penetrate the cover 43, and its tip is placed close to the molten copper 42. Further, a radiation thermometer 32 is provided at the rear end of the optical path securing tube 31. This radiation thermometer 32 is arranged with its light receiving part 33 located inside the rear end of the optical path securing tube 31, and is adapted to measure the temperature of the molten copper 42 through the optical path securing tube 31. ing. And the optical path securing tube 31
Air is blown into the optical path securing tube 31 through an air blowing tube (not shown) provided at the rear of the tube, thereby blowing smoke into the tube.
The temperature of the molten copper 42 is measured while preventing dust and flame from entering.

っている。As described above, in this radiation temperature measuring device 3, the optical path securing tube 31 is installed between the molten copper 42 and the light receiving part 33 of the radiation thermometer 32, and air is introduced into the optical path securing tube 31. Since smoke, dust, flame, etc. are not allowed to enter the blowing pipe, the temperature of the molten copper 42 can be accurately measured. That is, in the conventional measurement method that does not use an optical path securing tube, measurement errors are caused not only by smoke, dust, etc. but also by the flame of the burner 44. On the other hand, burner 4
The method used was to measure the temperature with the burner turned off and estimate the temperature during burner combustion, but this resulted in a considerable error depending on the amount of combustion in the burner, making accurate measurements impossible. In this regard, in the radiation temperature measuring device 3 described above, the light path securing tube 31 can prevent the flame from entering the light receiving section 33, allowing accurate measurement.

It is not necessary to limit this to this, and as shown in FIG. The opening at the tip of the optical path securing tube 52 may be covered with air blown out from the opening 53 to prevent smoke, dust, etc. from entering.
