英文摘要	The distribution and transfer mechanism of MnS inclusions are distinguished from the solute segregation in a 500 kg steel ball. The increase of MnS inclusions is obvious from the surface to the center of the steel ball, while the increase of solute content is slight. The massive MnS inclusions converge in the channel zone and in heterogeneous zones. During solidification, the interface tension drives MnS inclusions to the frontier of the dendritic zone. Some inclusions trapped may floatto induce the channel zone. Solidification contraction tears such channel zone to attract more melt enriched with inclusions. Some inclusions converge in the extra-dendritic melt. At later solidification stage, solidification contraction dominates the macro-distribution of extra-dendritic melt to produce the heterogeneous zones.
