    摘要： In accordance with an exemplary embodiment, a mold that solidifies molten steel injected to an inner space thereof includes a body having the inner space and a convex member that protrudes in a direction from an inner surface of the body to the inner space and has a protruding length gradually decreasing in a direction from the inner surface to the inner space.
    The mold in accordance with exemplary embodiments may suppress or prevent a surface defect and break out caused by contraction of a solidification cell in comparison with the related art. That is, the mold in accordance with the exemplary embodiments has an improved compensation rate with respect to the contraction of the solidification cell in comparison with the related art. Particularly, the mold in accordance with the exemplary embodiments has an improved compensation rate with respect to contraction in a short side direction of the solidification cell. Thus, a gap between an inner surface of the mold and the solidification cell may be suppressed or prevented to thereby suppress or prevent a solidification retarded phenomenon.
