Distribution of Ca-oxide, Ca-sulfide and MnS in Ca-added CC (continuous casting) steel slabs has been investigated by new X-ray microanalyser. The Ca plus S type inclusions were mainly observed in the segregated area. A thermodynamical consideration as well as the above experimental results revealed that the desulfurization by calcium-aluminate during the solidification had the dominent importance in the shape controlling mechanism. The desulfurization mechanism by calcium-aluminate inclusions is described.
