Abstract

In the present invention , in continuous casting by intentionally bulging cast slabs and then reducing the cast slabs that have an unsolidified layer , cast slabs are bulged without causing a breakout thereof and without causing internal cracking of the solidifying shell , and center segregation in the cast slabs as well as positive segregation near the thickness center are reduced. The degree of roller opening of a cast slab support roller (6) is set to be the same as the value directly under a mold until the thickness of a solidifying shell (11) of a cast slab (10) reaches 15 mm , following which the degree of roller opening is increased in a stepwise manner to cause the cast slab to bulge, at a total amount of bulging of 3- 20 mm. Then , the degree of roller opening is set to a constant at a section of 0.5- 5.0 m on the downstream side in a casting direction and next the cast slab the solid phase ratio in the thickness center of which is 0.2- 0.9 is reduced at least once by a reduction roller (7) under conditions where the multiplication product of the reduction speed and the casting speed is 0.3- 1.0 mm·m/min.
