Abstract
PURPOSE:To improve the quality and yield of a cast slab by executing secondary cooling satisfying the specific condition corresponding to length in the range, where bending of long side of the cast slab from lower end of a mold is supported. CONSTITUTION:They use (l) for the length in the range, where the projected bending of the long side of the cast slab 4 from the continuous casting mold 1 is supported, and L for distance from the mold 1 to solidified completing end at the min. thickness position of the cast slab. In the case of l<L, the secondary cooling is executed to the cast slab 4 in accordance with the condition shown by the inequality I. Further, in the case of l>=L, the secondary cooling is executed to the cast slab 4 in accordance with the condition shown by the inequality II. As the suitable secondary cooling is executed, the development of deterioration of defect at the time of cooling the cast slab is prevented and also shaped steel having large cross section can be produced. Therefore, the quality of the cast slab and the yield of product are improved.
