Summary:The mechanism of the occurrence of longitudinal surface cracks near slab corner has been investigated based on both the thermal stress analysis of solidifying shell in the continuous casting mold and experimental consideration. In the stress model, the coupling between thermal deformation of the shell and temperature distribution in the mold wall was taken into account. It is cleared that the conventional constant-tapered mold is insufficient to prevent the cracks. By applying a newly developed variable multi-tapered mold, which was designed from the stress analysis, the high-speed castings of 5m/min have been put into practice without corner cracks.
