Zusammenfassung:PURPOSE:To minimize the bulging of a cast slab and to improve the internal quality of the cast slab by drawing out the cast slab while reducing casting speed after completing the pouring of molten steel into a mold specifying the casting speed at the part where the molten steel surface level is lower than the ordinary level in the mold and successively drawing out the cast slab at the stationary speed. CONSTITUTION:A remaining unsolidified molten steel level 1a and a solidified shell (a) is positioned at 100mm below the upper end in the mold at the end stage of the casting. Successively, in the condition of reducing the casting speed at
