In order to determine the effect of interaction between superheat degree and combined EMS on dendritic structure and C,Mn homogeneity of heavy rail steel bloom,comparing experiment for different superheat degrees were carried out based on the specific combined EMS process.The effects of superheat degrees on the solidifying process and dendritic structure of bloom was qualitative analyzed by numerical simulate;the actual effects of interaction between superheat degree and combined EMS on dendritic structure and C,Mn macro segregation of bloom were further analyzed.Based on the analysis results the technical process improving the homogeneity and intensity of heavy rail steel bloom has been proposed.
