Abstract：Edge cracks are one of the common defects on the medium and heavy plate. The results showed that edge longitude cracks are the pucker caused by slab corner’s side-turn during the process of rolling. The edge cracks defect on the medium and heavy plate can be obviously improved by countermeasures such as increasing the steel purity, controlling the slab cooling, decreasing the transverse rolling, reducing the deformation rate of cross wedge rolling and improving the heating uniformity of slab.
