Abstract：Slabs with centre crack defects were dissected and rolled plate were detected. The samples were got from the severity laminate defect plate. Microstructures, morphology and composition were analyzed by SEM. Ferrite bands with inside sulfides stretched along the rolling direction in the laminate area were the main cause of plate laminate. The boundary condition of seaming and repairing of slabs interior defects after rolling were given.
