Effect of Sulfur in Slag on Dynamic Chan

In the steel production process, particularly during continuous casting, it is crucial to minimize slag entrapment in liquid steel by effectively controlling the interfacial tension between the two materials. This study investigates the dynamic changes in the liquid iron/molten slag interfacial tension, which are influenced by redox chemical reactions occurring at the interface. Through a series of experiments, the authors explored how variations in sulfur content in the slag impact the interfacial tension behavior. The methodology involved analyzing the interfacial behavior under different chemical conditions to understand the equilibrium and dynamic changes. Results indicate that increased sulfur concentration in the slag corresponds to measurable alterations in interfacial tension, as influenced by adsorptive phenomena of oxygen atoms resulting from slag component decomposition. Such findings enhance understanding of the interfacial dynamics and provide insights for optimizing the continuous casting process in steel production, consequently reducing slag entrapment and improving steel quality.
