ABSTRACT:
The width of a slab can be easily increased during a continuous casting operation by a simple method, wherein casting of a molten steel is temporarily stopped during the continuous casting operation, the narrow side of a casting mold is moved to a predetermined width, corresponding to the increased width to be of the slab, to form a space between the narrow side of the mold and the solidified shell of a slab, a closing member having a width 1-5 mm smaller than the increased width of the slab, and a cooling and sealing material are inserted into the space to form a clearance of 1-5 mm between the closing member and the narrow side of the mold, and the casting of the molten steel is again started.
