It was found that a large number of inclusions with various sizes were suspended in a molten steel taken from a tapping ladle and the number of fine inclusions did not decrease by killing for about 20 min. The chemical composition and the number of these inclusions were determined. The distribution of inclusions in the bottom half of 7 ton ingots was inverstigated, taking above results into consideration. In particular, diffusion growth mechanism was applied theoretically for the growth of inclusion in the negative segregated zone of these ingots. Observation of macroscopic inclusions, which appeared in the negative segregated zone of a 90 ton ingot, indicated that the formation of the inclusions was closely related to the solidification condition in the region.
