Abstract (en)

[origin: EP3560629A1] According to one technical aspect of the present invention, a continuous casting method is performed in a continuous casting apparatus having a plurality of segments continuously provided, so as to continuously cast a slab drawn from a mold, and can comprise the steps of: rough milling the slab by setting a roll gap difference between an input side cylinder and an output side cylinder of an N-th segment as a first roll gap difference when the slab is drawn from the mold; and variably reducing the thickness of the slab by setting the roll gap difference between the input side cylinder and the output side cylinder of the N-th segment as a second roll gap difference smaller than the first roll gap difference, when the slab is not drawn from the mold. The second roll gap difference can change according to a distance between the end of the slab and the N-th segment.
