Abstract：There were serious transverse corner cracks on continuous casting slab of low alloy steel in Panzhihua Steel before, and study on the control of slab quality had been carried out. Some effective countermeasures are put forward, such as the optimization of primary cooling system and mold powder. Industrial tests show that the transverse corner cracks on continuous casting slab have been significantly reduced, and the reject rate of hot rolled sheet caused by the transverse corner cracks is reduced from 7.2% to 0.74%.
