Abstract

Provided is a method for manufacturing a slab that enables the production of a slab of appropriate quality. The method for manufacturing a slab manufactures a slab of a predetermined size by using a continuous casting machine. The method for manufacturing a slab includes a soft reduction region setting step of setting a soft reduction region in the continuous casting machine, the soft reduction region containing a starting point for performing soft reduction on the slab and an endpoint at which the soft reduction is terminated, the soft reduction region being set based on a condition of cooling water for cooling the slab, in the continuous casting machine, a casting speed of slab, and a solid phase ratio of the slab determined from a composition of the slab; a reduction gradient setting step of setting a reduction gradient for the soft reduction region based on a thickness of the slab, a width of the slab, and the casting speed of slab; a secondary cooling intensity setting step of setting a first intensity section and a second intensity section, which are sections for performing secondary cooling in the soft reduction region, based on the solid phase ratio of the slab, the second intensity section being a section in which the secondary cooling is performed with a higher intensity than in the first intensity section; and a continuous casting step of performing continuous casting by using the set soft reduction region, reduction gradient, first intensity section, and second intensity section.
