Abstract：The causes of edge crack for casting blank was discussed. The results showed that the cracks are connected with gas content of molten steel, mold oscillation parameters and process of secondary cooling system. The surface quality of casting blank is improved by strengthen protection cast process, optimization technological parameters, controlling straightening area temperature so that the edge crack rate of high strength ship plate is reduced from 4.5% to 1.8%.
