“…Therefore, SiO 2 and P 2 O 5 [ 117 , 118 , 119 , 120 ] will directly cause the viscosity of the slag to increase, while the role of amphoteric oxides will have different effects on the fluidity of slag according to changes in relative composition and temperature. Figure 2 c shows that the influence of Al 2 O 3 on the viscosity of slag is obviously different under different composition conditions [ 121 ]. The roles played by amphoteric oxides such as Cr 2 O 3 [ 122 ] are similar to those of Al 2 O 3 .…”

Molten slag has different properties depending on its composition. The relationship between its composition, structure, and properties has been the focus of attention in industrial manufacturing processes. This review describes the atomistic scale mechanisms by which oxides of different compositions affect the properties and structure of slag, and depicts the current state of research in the atomic simulation of molten slag. At present, the research on the macroscopic properties of molten slag mainly focuses on viscosity, free-running temperature, melting point, and desulphurization capacity. Regulating the composition has become the most direct and effective way to control slag properties. Analysis of the microevolution mechanism is the fundamental way to grasp the macroscopic properties. The microstructural evolution mechanism, especially at the atomic and nanoscale of molten slag, is reviewed from three aspects: basic oxides, acidic oxides, and amphoteric oxides. The evolution of macroscopic properties is analyzed in depth through the evolution of the atomic structure. Resolution of the macroscopic properties of molten slag by the atomic structure plays a crucial role in the development of fundamental theories of physicochemistry.

The development of refining slag is the core of the ladle furnace (LF) refining processes and is essential for fast and effective desulfurization refining. Desulfurization reactions are mainly determined by slag–steel interactions, which are closely related to the physicochemical properties of slags. This study reviews the research progress of desulfurization refining slag for the LF process. First, the chemical composition of the refining slag was described, and then three theories of desulfurization and the concepts of sulphide capacity and sulfur partition ratio were introduced. Second, the effects of operating parameters and slag components on desulfurization were examined. Furthermore, the microscopic analysis of the desulfurization process was performed. The prediction models of slag properties related to desulfurization were summarized. Finally, a research direction for LF desulfurization refining was proposed. The question of how to ensure the uniformity of desulfurization remains open. The industrialization of the new refining slag developed by replacing CaO with BaO or Li2O and replacing CaF2 with B2O3 should be accelerated to solve the CaF2 slag volatilization problem. One of the most pressing issues that must be addressed is improving the accuracy of the existing slag performance forecast model.This article is protected by copyright. All rights reserved.
