This study investigates the chemical reaction between glazed refractory materials and Al-deoxidized molten steel, emphasizing the influence of calcium treatment at 1,600°C. Non-metallic inclusions in the steel refining process can arise from both endogenous and exogenous sources, with ladle glaze identified as a significant contributor to melt contamination. Drawing from previous research, the current work examines how calcium treatment affects the chemistry of the glazed refractory and the formation of non-metallic inclusions. Using scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and energy dispersive spectroscopy (EDS), the evolution of the refractory material's chemical composition and inclusions is analyzed. Additionally, FactSage thermodynamic software is employed for thermo-chemical analysis of the reactions involved. The results indicate that calcium treatment modifies the interaction between the glazed refractory and molten steel, with implications for improving steel cleanliness. This research ultimately contributes to a better understanding of ladle glaze formation and its impact on steel quality during the refining process.
