Abstract：The results of industrial experiment of continuous temperature measurement system for molten steel in CC tundish, by infrared ray that is based on the principle of color contrast, are described. The principles and specifics of different infrared measuring systerms are analyzed. The erosionresistance and heat shock resistance tests of high conductivity ceramic tube for temperature measuring are reported. The effects of temperature, pressure and flux of cooling gas on the cooling of temperature measuring gun are also reported. The accuracy and stability of measurement, the reliability of equipment and the response time of temperature are analyzed. Comparing with the measurement with PtPtRh thermocouple, the advantages and disadvantages of continuous infrared temperature measurement system based on color contrast are analyzed.
