To provide a continuous casting mold which can manufacture a slab with a good quality by suppressing and preventing the solidification delay of the slab in a corner part of the mold, and further suppressing the deterioration in the quality of the corner part of the slab due to the excessive taper (excessive restraint), and is effective for reducing premature wear of the corner part of the mold due to the excessive taper.
The continuous casting mold 10 includes short piece members 11, 12 disposed so as to be faced each other at an interval and long piece members 13, 14 disposed so as to be faced each other while holding them from both sides in the width direction, cools molten steel inside a space 15 formed thereby to downwardly draw it while solidifying, and manufactures the slab with a plate thickness of 600 mm more, wherein the respective intervals between the short piece members 11, 12 and long piece members 13, 14 are reduced according to a solidifying and contracting shape of the slab toward the drawing direction of the slab, and the inner cross sectional shape of the long piece members 11, 12 satisfies the predetermined formula within the range from the liquid surface of the molten steel downward to 200 mm and the range below 200 mm.
