N2 - The Fourier Transformed Infrared (FTIR) spectra analysis of two fluxes used in the thin slab casting process of steel were carried out in order to identify the mineralogical species present in fluxes as received and after a heat treatment to 1573 K and further solidification at two different cooling velocities. Fluxes as received show the presence of wollastonite (CaO·SiO2) and a sodium carbonate (Na2CO 3) as the main components; after the heat treatment, there was almost a whole transformation from the original compounds to cuspidine (3CaO·2SiO2·CaF2) and nepheline (Na 2O·Al2O3·2SiO2) phases. These results were confirmed by X-ray powder diffraction (XRD) to the slowly cooling velocity. The FTIR technique is proposed as a useful and complementary technique to X-ray diffraction to study the structure of commercial fluxes for thin slab casting.
