幅になるほど顕著になる。Problems to be Solved by the Invention According to the above-described conventional configuration, the mold roll for the purpose of casting the slab has only to have a function of supporting the solidified slab, and the roll cylinder 32 is only the peripheral portions at both ends of the roll body 31. Are welded to each other and the cooling grooves 32 are not joined. Therefore, the center tends to expand due to thermal expansion. Also, the temperature is rather low due to the contact of the solidified slab. However, in the case of continuous casting of thin plates, the temperature is higher than that of the slab because it is directly in contact with the molten metal, and the thermal deformation in which the central part swells greatly affects the cast pieces of the thin plates. And the influence becomes more remarkable as the slab becomes wider.
