Effects of Axial Static Magnetic Field on Inclusions Removal in the Liquid Melt Film During Electroslag Remelting Process

Magnetic-controlled Electroslag Remelting (MC-ESR) process has been proposed to improve the inclusion removal efficiency in recent years. In this study, the effects of axial static magnetic field (ASMF) on liquid melting film (LMF) and inclusion removal during this period in ESR process of GCr15 steel were studied by a series of MC-ESR experiments. The thickness of the characteristic position of LMF was reduced by 18.6 to 90.3 pct when a 50 mT...
