<p>This method for continuous casting is provided with an extraction step for extracting a cast slab in a solid-liquid coexisting state from a cylindrical casting mold, a first rolling reduction step for performing rolling reduction of the cast slab in the solid-liquid coexisting state in a first rolling reduction direction perpendicular to the longitudinal direction of the cast slab after the extraction step, and a second rolling reduction step for molding the cast slab, in a completely solidified state in which the temperature of a center part thereof is higher than the temperature of a surface part thereof after the first rolling reduction step, into a rounded rectangle having rounded corner parts as viewed in cross-section perpendicular to the longitudinal direction of the cast slab, while performing rolling reduction alternately in the first rolling reduction direction and a second rolling reduction direction, the second rolling reduction direction being a rolling reduction direction orthogonal to both the first rolling reduction direction and the longitudinal direction of the cast slab.</p> |
