The temperature measurement of continuous casting slab is of importance for process control and product quality control control. However, the accuracy of radiation temperature measurement of high temperature casting slab during continuous casting process is greatly affected by the environmental factors, such as water vapor, spray, water film and other participational media. The radiation characteristics of water vapor, spray and water film and their influences to radiation temperature measurement of continuous casting slab were investigated. Based on the high-temperature spectra line spectrum database (Hitemp) and the principle of monochrome thermometer, colorimetric thermometer, the measuring errors under each operating infrared spectral wavelength were calculated. Results showed that spectral region with wavelength near 1.0μm or 1.6μm would be the optimum for high temperature infrared thermometer used under the conditions with moist steam, water spray and water film at the secondary cooling zone in steel continuous casting.
