Abstract

PURPOSE:To make it possible to measure the temperature of the body accurately by radiation temperature measuring method, by irradiating light on the surface of the body, and measuring a diffused reflection coefficient from a ratio of the mirror reflected light and the diffused reflected light around said light by an on-line method. CONSTITUTION:The energy radiated from the body 10 is directly inputted to a radio meter 16, or it is reflected by a reflecting mirror 12 and the surface of the body 10 and inputted to a radio meter 16. Directly inputted radiation energy E1 and E2 which is the sum of the E1 and the radiation energy which is inputted after the reflection are measured. The light B is irradiated on the surface of the body 10 and reflected by the mirror surface, and the light I1 is obtained. The ratio of the I1 and the diffused reflected light I2 around the I1 is obtained. Then, the diffused reflection coefficient of the surface of the body 10 is obtained. The surface temperature of the body 10 is obtained from said radiated energy E1 and E2 and the diffused reflection coefficient P. For example, a measuring device 42 of the diffused reflection coefficient P is provided at the input side of a furnace 40, a sensor part 44 is provided at the output side, and emissivity epsilon of the strip 10 are the temperature T are computed by a computing device 46.
