Abstract
PURPOSE:To make it possible to accurately calibrate a value of temperature obtained by a thermocouple, by seeking a radiation energy from a steel plate at the time when a difference, which is obtained by subtracting an amount of direct incidence from a sum of an amount of direct incident to a radiometer and an amount of incidence after reflection on a mirror surface, takes the maximum value, and then, by obtaining a real steel plate surface temperature by using a prescribed equation. CONSTITUTION:A radiometer 12 and a reflector 14 are arranged on a heated steel plate 10, which is an object of temperature measurement, in such a manner that energy radiated from the steel plate enters the radiometer directly and also indirectly after reflecting upon the reflector and surface of the object. By measuring E1, which is the radiation energy, and E2, which is a sum of the E1 and a radiation energy entering after the reflections, and also by changing the rate of radiation from the steel plate surface while keeping the steel plate temperature constant, the radiating energy E1 at the time when a difference DELTAE=E2-E1 is the maximum is sought, and by using a relative equation EbT=2/r.E1* (r in the equation signifies permeability of filters 18 and 20) between the value E1* and a blackbody radiating energy, a surface temperature T of the steel plate is sought. And, a thermocouple 24 is installed in the neighborhood of the steel plate temperature measuring section to obtain an indicative temperature T, and a temperature Ta is calibrated by the temperature T.
