Abstract
A surface temperature measuring apparatus comprising a radiation thermometer configured to detect thermal radiation light emitted from a surface of a temperature measurement target material in a cooling process with water, a housing having an opening on a temperature measurement target material side, the housing storing, in an inside of the housing, at least a light receiving unit of the radiation thermometer among structural elements of the radiation thermometer, and an optical glass that is fit and sealed in the inside of the housing between the temperature measurement target material and the light receiving unit of the radiation thermometer, the optical glass being configured to transmit the thermal radiation light. The optical glass has, on the temperature measurement target material side, an end surface adjacent to the surface of the temperature measurement target material. A surface temperature measuring method is also provided.
