“…The physical characteristics of the slag, particularly its viscosity and surface tension coefficient, are often the ones that can be changed. According to a force analysis model, a study [ 65 ] examined the impact of changes in physical parameters on the removal of liquid calcium aluminate inclusions that were 20 μm in size. The maximum displacement of the inclusions above the interface is most significantly influenced by the interfacial tension between the slag and the other two phases, particularly the interfacial tension between the steel and the inclusions (σMI) and the interfacial tension between the steel and slag (σMS).…”

“…[60] The most basic fluid motion and inclusions forces are still based on empirical formulas, which cannot cope with complex and variable interface situations. [1,15,[58][59][60][61][62][63][64][65][66][67] In their study, Xuan et al [59] discovered that the separation and removal of inclusions are significantly impacted by the deformation process of the steel-slag interface. They came to the conclusion that the model should be constructed taking the interface's deformability into account by including steel-film evacuation and an interfacial curved moon surface, as shown in Figure 5.…”

“…The key elements in the separation of inclusions at the steelslag interface, according to Strandh [65,66] and Valdez et al, [64] showed that the tension and viscosity of the top slag are the key elements in the separation of inclusions at the steel-slag interface. These factors influence the interfacial energy between inclusions and slag, which is the main factor that prevents inclusions from crossing the steel-slag interface.…”

The removal of inclusions in liquid steel has always been the focus of research, and the removal of inclusions is mainly through the process of the inclusion through the slag–steel interface. The inclusion removal process can be subdivided into inclusions in molten steel grew up rise, in steel–slag interface through separation, adsorb dissolved in molten slag 3 steps. Based on the microscopic process of three steps, this article summarizes and discusses the mathematical model, fluid mechanics model, and experimental verification method of inclusion removal process, analyzes limiting and influencing factors of inclusion removal process, and comprehensively describes the numerical simulation research progress of inclusion removal process. With the development of numerical simulation techniques and experimental equipment, some progress has been made in the study of interfacial removal of inclusions. The inclusion interface removal behavior can be analyzed semiquantitatively based on dynamic force model. The computational fluid dynamics model has advantages in studying the phenomena of the inclusion interface, and the phase‐field method is often used to simulate the removal process of the inclusion interface. The combination of water model and numerical simulation, high‐temperature laser confocal method, and other methods is of great help to explore the interface behavior of inclusions.
