Multispectral system for measuring the radiation parameters of steel slag during the discharge of steelworks furnace

This paper presents recently developed a multispectral system for measuring and calculation the chosen radiation parameters of the steel slag for the investigation of FeO content. The system contains 2 infrared (IR) and 2 visual (CCD) cameras. IR cameras capture images in MWIR and LWIR spectral ranges. The visual broad band optical system acquires the images in NIR and visual (RGB) subbands. The short band pass optical filters are used in visual spectral range. CCD RGB camera is used to select the proper wavelength bands in the visual range. The main objective of the research is to define different thermal and optical parameters of the steel slag stream for further image classification and FeO content estimation.
