摘要
Understanding the transformation mechanism of the viscosity of the CaO-SiO2-FexO slag is of great significance for improving the quality of liquid steel and ensuring the smooth smelting process. In this study, the viscosity values of the CaO-SiO2-FexO system at different temperatures were measured, and its melt structure was analyzed by Raman spectroscopy. The microstructure analysis of the viscosity was then given from the perspective of melt structure. On this basis, a viscosity prediction model that depends on the concentration of oxygen bonds was established using the molar fractions of oxygen bonds calculated by structural analysis. By comparing the measured and calculated values of viscosity, it was found that the deviation of all data was within 0.1 Pa s, showing the higher accuracy and stability of the current model.
