【Abstract】 Based on the experimental data for 280 mm×380 mm concasting bloom of heavy rail steel, the effect of current intensity of M IEMS mould electromagnetic stirring and concasting parameters such as casting speed and overheating degree of metal on central carbon segregation of bloom has been studied by regression analysis. The results obtained that with increasing current intensity, the central carbon segregation index decreased which was linear with the current intensity.更多还原
