“…Pure MnS is soft and can be deformed during hot deformation. [12,45,46] Sulfur content over 60 ppm in steels contributes to the formation of MnS with a high aspect ratio. [47] Calcium treatment can modify the shape and composition of MnS and therefore improve the machinability such as reducing tool wear during machining.…”

Sulfides like MnS are common phases in resulfurized free‐cutting steels, and required to be controlled during the hot working process due to its influence on machinability, mechanical and physical properties of final products. This article extensively reviews published researchs on sulfides in resulfurized free‐cutting steels. The formation mechanism and modification of MnS during steelmaking, casting, and heat treatment are discussed based on a number of relevant studies. Measures to control the morphology and number of sulfides are supplied, which are beneficial for the producing of resulfurized free‐cutting steels with high quality. Thermodynamic calculation proves to be an effective method to predict and control sulfides.This article is protected by copyright. All rights reserved.

“…The elimination of inclusions by the bubble wake is more effective at larger bubble diameters or higher concentrations of inclusions. According to Wang, [ 14 ] the bubble dispersion degree and bubble size attained a good consistency when the flow rate of soft blowing argon for a 100 ton ladle was between 80 and 110 L min −1 , when the removal efficiency of inclusions was high, and when the cleanliness index in steel stayed above 0.97. Bubble adhesion makes it easier to eliminate larger inclusions because the chance of adhesion between the bubble and the inclusions increases with the size of the inclusions.…”

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.
