SOLUTION: The cast slab length LO in each kind of steel is corrected as LO=W/(ρ+t+w) and the cast slab is cut off with the instructed cutting-off length L as L=LO×(t/T). Wherein, W is the instructed weight of the cast slab (t), ρ is the sp. gr. (t/mm<3> ), (w) is the instructed width of the cast slab (m), (t) is the nominal thickness of the cast slab (mm), T is the thickness of the cast slab in each kinds of steel (mm). The weight deviation developed peculiar to each kind of steel can be reduced by executing this correction. The cutting-off length is calculated by replacing the instructed thickness of the cast slab with the actual thickness of the cast slab in each kind of steel. Molten steel 15 is cast into a mold 10 from a tundish 11 and the drawn-out continuously cast slab 2 is cooled with cooling water and solidified.  The cast slab is straightened with a straightening device 5 and cut off into a desired length of the cast slab with a cutting device 4.
