Provided is a continuous cast slab and a manufacturing method for the same, wherein solidified layers of a cast slab having a non-solidified layer are compressed with each other during a continuous casting process to fundamentally prevent occurrence of defects, such as center segregation or porosity, which deteriorate quality of the cast slab, thereby decreasing defects. A continuous casting method for producing a cast slab by drawing molten steel from a mold includes preparing a compressing unit, and reducing at least one side of the drawn cast slab by using the compressing unit, wherein solute-enriched residual molten steel is caused to flow back in a direction opposite to a casting direction. Thus, it is possible to produce a cast slab wherein defects such as center segregation are greatly eliminated. |
