| Abstract: | The formation reasons of transverse corner cracks on the surface of continuous casting slab were analyzed based on the continuous casting process. The accuracy of the equipment and the control measures were put forward. The slab corner crack rate was reduced from 5 % to 0.5% after taking these measures. |
