“…CLSM has been used to investigate the precipitation and evolution of the inclusions by many researchers. 12,13 In the present work, an ultrahigh-temperature CLSM was employed to analyse the interaction between the inclusions. Figure 5 exemplarily shows the results of inclusion agglomeration in heat 1 and heat 3, respectively.…”

To investigate the evolution mechanism of Al 2 O 3 inclusions after Mg treatment in H13 die steel, the determination of inclusions characteristics and thermodynamic calculation were carried out in the present study. The results showed that irregular and cluster Al 2 O 3 inclusions in H13 die steel were modified to MgO•Al 2 O 3 and MgO after Mg treatment. Two types of MgO•Al 2 O 3 were detected after Mg treatment. The long-range gravity between the MgO-containing inclusions is weaker than that of the MgO-free inclusions. The long-range gravity between the inclusions decreases with the increasing of Mg content of the steel. The evolution mechanisms of inclusion in low Mgcontaining and high Mg-containing H13 die steel were comprehensive discussed. The different reaction mechanisms result in the different of the core of the MgO•Al 2 O 3 inclusion.

“…In particular, hard alumina inclusions are known to be detrimental to the mechanical properties of steel welds as well as to the steel materials themselves. [1][2][3][4][5][6] Since alumina inclusions also affect the formation of internal stress, the control of morphology and size of alumina inclusions in aluminum killed (AK) steels has been an important focus in the steel industry. 7) Okohira et al 8) found that dendritic alumina was enhanced at relatively high Al concentrations, i.e., 0.04-0.06 mass%, in low carbon aluminum killed (LCAK) steel.…”

“…According to the results of CFD model simulations, [ 114 ] whereas small inclusions float in a laminar state, where their own bulk force is insignificant in comparison to the interface force, large inclusions float in a turbulent state, where the bulk force operates in conjunction with the interface force. Increased inclusion size will increase the likelihood of inclusions vibrating at the interface, [ 15 ] as research has shown [ 115 ] that inclusions with diameters of 150–250 μm will not be able to pass the contact into the slag layer and will instead remain there.…”

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.
