Abstract
High-performance alloy steel is distinguished by its purity. Inclusion contamination and oxygen addition to the steel due to long contact between the refractories of the tundish and the steel should be avoided. In this study, the static crucible method was used in the interaction experiments between MgO–CA6 composite and low carbon alloy steel. The effects of different proportions of MgO–CA6 on the content of alloying elements in steel were analyzed. Morphology, quantity, size, and distribution of inclusions were also examined. The results indicated that more inclusions (e.g., MnO, FeO, and MnS) were generated between the MgO material and alloy elements (e.g., Fe and Mn) in molten steel. The oxygen content in molten steel of CA6, MgO–0.28CA6, and MgO–0.70CA6 materials, as well as the number of inclusions, were sharply reduced. The particle size was smaller, resulting in good molten steel purification ability. The oxygen content of the steel in contact with the MgO–0.28CA6 material was relatively low, characterized by a reduction in the proportion of inclusion area and particle.
