PROBLEM TO BE SOLVED: To provide a continuous casting method by which in a method for continuously casting a steel, cast while pressing corner parts of a cast slab, the development of transverse crack can further be prevented by limiting the surface temperature of the cast slab at the time point when the corner parts are pressed. SOLUTION: When molten steel is continuously cast while pressing the corner parts of the cast slab 12 with a spinning wheel state roll 18 or rolling-reduction rolls 19 at least an upstream side from a correcting part of a continuous caster, the corner parts are pressed under state of being≥900°C the surface temperature at the corner parts of the cast slab. Then, oscillation mark is pressed so as to become the flat, and the transverse crack is prevented. COPYRIGHT: (C)2007,JPO&INPIT
