To stably measure a surface temperature of a steel material as an object of temperature measurement by excluding temperature-measurement inhibitors.SOLUTION: A surface temperature measurement method is for measuring a surface temperature of a steel material as an object of temperature measurement by a radiation thermometer. The radiation thermometer is arranged in a housing having an optical window, and an angle formed between an optical axis of the radiation thermometer and a normal direction to a surface of the steel material as the object of temperature measurement is an angle of 60° or less. The optical window is arranged on the optical axis of the radiation thermometer, and an angle of inclination is 30 to 90° in the gravity direction. The optical window is coated with a film of liquid flowing from above to below the optical window, and the surface temperature of the steel material as the object of temperature measurement is measured.SELECTED DRAWING: Figure 2 【課題】測温の阻害因子を排除して被測温鋼材の表面温度を安定して測定することを可能にする。【解決手段】放射温度計により被測温鋼材の表面温度を測定する表面温度測定方法であって、放射温度計は、光学窓を有する筐体内に配置され、放射温度計の光軸と被測温鋼材の表面の法線方向とのなす角度を６０°以下とし、光学窓は、放射温度計の光軸上に配置されており、重力方向に対する傾斜角度を３０°以上９０°以下として、光学窓を、当該光学窓の上方から下方へ流動する液体の膜で被覆して、被測温鋼材の表面温度を測定する。【選択図】図２
