“…Zhong et al [8] studied the effect of a transverse static magnetic field on microstructure and properties of GCr15 bearing steel in the electroslag continuous casting process, and found that the presence of a static magnetic field was beneficial for microstructure refinement as well as inclusion and harmful elements removal. Guo et al [9][10][11] studied the change of inclusions during the electroslag remelting process assisted by a static magnetic field, and found the kinetic conditions for inclusion removal were enhanced, leading to a decrease in the number and size of inclusions.…”

As a special metallurgical method, electroslag remelting (ESR) technology has been widely used. The most remarkable advantage for ESR is that it can improve the purity and solidification quality of metal. In the traditional metallurgical process, molten steel is treated in lined vessels from smelting to casting. The molten steel will inevitably be polluted by the lining, such as the spalling of refractory, and the involvement of mold flux [1] . These accidental and irregular large inclusions have a very adverse effect on the properties of metals. In the ESR process, the contact area between slag and molten

An axial static magnetic field (ASMF) is superimposed during the electroslag remelting (ESR) process to regulate the inclusion removal (GCr15 bearing steel) in the current study. After applying a 50 mT ASMF, the metal pool of the ESR ingot becomes shallower and the solidified dendritic structure tends to grow axially, together with a higher inclusion removal efficiency. The number of inclusions in ESR ingot decreases, and the inclusion with larger size (>10 μm) is almost eliminated. By tailoring the morphology of the liquid melt film (LMF), droplet, and metal pool, the ASMF applied in this study strengthens the kinetic conditions (inclusion migrated to slag/metal interface) for the inclusion removal, thus realizing the multi‐stage enhanced removal of inclusion during ESR process.
