|1. (WO2018199187) SCALE COMPOSITION DETERMINING SYSTEM, SCALE COMPOSITION DETERMINING METHOD, AND PROGRAM|
|Applicants:||NIPPON STEEL & SUMITOMO METAL CORPORATION
|Title:||SCALE COMPOSITION DETERMINING SYSTEM, SCALE COMPOSITION DETERMINING METHOD, AND PROGRAM|
If the spectral emissivity at one wavelength and/or another wavelength measured by means of a spectral emissivity measurement radiometer (21a, 21b) is not in a prescribed range including the spectral emissivity of FeO at the one wavelength and the other wavelength, then a scale composition determining device (10) determines that Fe2O3 has been generated in the outermost layer of scale (SC), and otherwise determines that Fe2O3 has not been generated in the outermost layer of the scale (SC).
