PROBLEM TO BE SOLVED: To improve the dimensional precision of a cast strip by arranging plural hydraulic forming units arranged on a large size fixed supporting shaft at the inside of roll shell and executing the shape control of a roll. SOLUTION: The casting roll 1 is provided with a hollow supporting shaft 9 and the shell 6 and an outside cylinder being in contact with a casting metal is formed with the shell 6. Further, plural shell deforming elements composed of a piston 8 and a working pat 12 are arranged in the roll axial direction between die shell 6 and the supporting shaft 9 so as to be independently workable in each, and while supporting the reaction force to the supporting shaft 9 during casting, the shell 6 in just above range thereof is deformed to give a desirable outline. Then, the deforming element lines are arranged in the opposite sides at 180 deg. in the upper and the lower sides on the casting roll 1. Further, the rotation of the shell 6 is executed with a center flat gear arranged on a driving shaft 91 inserted in the center hole 90 of the supporting shaft 9 through an intermediate gear 93, and the cooling is executed by supplying coolant into channel in the shell 6 through the supporting shaft 9. |
