Abstract

PURPOSE:To enlarge a controlling range and to form a product profiled a complex mother shape of roll, by making back-up rolls of a sextuple rolling mill, having work rolls with roll benders and movable internal rolls, as crown-changeable rolls. CONSTITUTION:Internal rolls 1 are movable in the direction of the width of a rolling material M, and work rolls 2 are equipped with roll benders as shown by the arrow 3. Back-up rolls 4 are crown-changeable rolls, and the amount of the crown is adjusted by the press. of highly pressurized medium to a press, chamber 43. The press., acting between the rolls 2, 1, dissolves the peak of press. distribution existing between the edge and a quater part of the material M in the direction of its width, by this adjustment; further, in the same manner, the peak of press. distribution between the rolls 1, 4 is dissolved. Accordingly, the quarter elongation of the material M is prevented.
