In this paper 82 B steel billet cast by a Chinese domestic steel plant had been investigated with regards to the distribution of V-shape segregation in transverse and longitudinal section,and center segre-gation of carbon as well.The results showed that V-shape segregation occurred in central equiaxed crystal zone,and carbon segregation was much serious in V-shaped channels;The generation of V-segregation is related with flow of solute enriched liquid and solidification structure.Both expanding equiaxed crystal zone and refining the equiaxed crystal zone are two effective ways to reduce V-segregation.
