In Situ Observation of MnS Inclusion Behavior in Heavy Rail Steel during Heating

摘要：

　　The change process of MnS inclusions in heavy rail casting slab was in-situ observed by confocal laser scanning microscope.The result shows the MnS has shape evolution owing to the influence of the diffusion and dissolution with the increase of the temperature.The small-sized MnS inclusion with spindle and nearly spherical shapes in continuous slabs are obtained with proper heating temperature between 600℃ and 870℃ or 1150 ℃ and 1200℃,and the excessive heating temperature can cause size increase of MnS inclusion.
