Second, this roll is stood vertically and rotated around its axis: while it is lowered vertically at a very low speed, it is heated by an induction heating device, and at the same time, cooling water is injected onto the heated surface directly below it. A method of continuous hardening is used.

特別の考慮が必要とさ４・する。However, at the bottom of the area where the temperature should be measured, cooling water is sprayed toward the heated roll surface, causing a large amount of steam and water droplets to form on the surface of the roll. Therefore, the use of optical (non-contact) sensors such as radiation thermometers in such locations requires special consideration.

に対しても悪い影響を与えていた。When using the radiant temperature h1 in a place like this J, this, this, etc., purge air between the strips is continuously blown from around this area toward the object to be measured, and the steam that tries to enter the field of view is removed. The 7j method for removing obstacles such as water droplets has been attempted.
This method lowers the temperature of the object to be measured,
Not only was it impossible to accurately measure the temperature, but it also had a negative effect on the object to be measured.

Detection is possible each time. The signal generated by the pulse generator 4 is set so that the temperature measurement interval is about 10 seconds and the interrogation time of the shield plate 9 is about several tens of milliseconds. Therefore, the object to be measured 14 is almost never cooled by the air flow 71 (the time of collision is extremely small, so it is caused by the jet stream of C1 air), and a decrease in the accuracy of horse measurements is a problem. It is a degree that does not become.

1; A light-receiving part of the crystal is installed inside, and air or other gas is injected from the tip part, and a shielding plate is installed to intermittently block the flow of the injected gas. It detects the energy produced by the equipped probe body and the object to be measured and outputs an electrical signal corresponding to the temperature! ) I thermometer, a signal processor for continuously outputting a signal corresponding to the temperature by holding the output of the radiation thermometer detected intermittently for 1 time, and a shield plate 9 and the signal processor for intermittently detecting the output of the radiation thermometer. It has a timing pulse generator to operate the probe body intermittently and in a short period of time, injects gas from the probe body to the object to be measured, and detects the surface temperature of the object to be measured within this time. The temperature measuring device of the present invention is characterized by continuously outputting a signal, and the temperature measuring device of the present invention can be used even in a bad environment where steam, water droplets, dust, etc. are scattered on multiple floors. The surface temperature of the object to be measured can be measured accurately and continuously, and its integrity and utility value are extremely large.
