Abstract

The morphology, size and distribution evolutions of MnS inclusions in molten steel were investigated by electropulsing. The results show that angular MnS inclusions distributed randomly in the untreated as solidified steel, in contrast to chain-like formations on the surface of the steel under the treatment of electropulsing. It indicates that the passing electric current enables to move the inclusions toward the surface where inclusions achieve much larger size with modified morphology. The MnS changes in morphology and size and its distribution depend on the modified interfacial energy and free energy by electropulsing. Therefore, electropulsing treatment provides a special and effective approach to control inclusions in molten steel to improve their mechanical, physical and corrosion resistance properties.
