Abstract
A continuous casting method for steel in which a slab at a position where the center solid phase rate of the slab is 0.8 or more and including after complete solidification is reduced by a reduction roll. The roll outer peripheral shape in a cross-section including a roll rotation axis convex shape overhanging outward in a region including a width-direction center position of the slab. The convex shape is a shape that does not have corner portions in a convex shape defining range with a total length of 0.80×W on both sides in the roll width direction from the width-direction center position. A reduction roll radius at the width-direction center position is greater by 0.005×t or more than a reduction roll radius at both ends of the convex shape defining range.
