Although continuous casting is the dominating casting process nowadays, the operators still face several challenges. These can be product defects and operational difficulties, like different cracks, non-metallic inclusions, breakouts or the appearance of clogging, respectively. To detect clogging and refractory wear at an early stage and thus avoid more severe problems, a new approach was tested in this work. The main objective was to answer whether the detection of clogging and refractory wear can be measured using contactless temperature measurement. Thus, developing a laboratory trial set-up was necessary to conduct measurements with various contactless temperature measurement methods, e.g., Infrared Camera, Pyrometer, and Broadband Spectral Thermometer. Furthermore, thermocouples were used as a reference. The different methods were compared concerning the end temperature difference and the heating rate of the different samples to find the most sufficient method to detect clogging and refractory wear. It was found that the detection of both, clogging and wear, is possible in a laboratory scale. This is true if the end temperatures are taken into consideration as well as in case of the comparison of heating rates. Whereat, the pyrometer showed the best results.
