Abstract

PURPOSE:To change the diameter of a roll correspondingly to the shape of a material to be rolled, and to make the shape control for the material to be rolled easy, by forming the longitudinal middle part of a backup roll into a solid body, and by arranging a gap on each of longitudinal both sides of the middle solid part in order to receive a working fluid therein. CONSTITUTION:In a four-stage rolling mill, an approximate middle part of the drum length of both or either one of upper and lower backup rolls is formed into a solid body; a shaft 3 is inseted into a tapered hollow cavity provided on longitudinal both sides of this middle solid body so as to form a conical, annular gap 4 between the shaft 3 and the roll 2a. A working fluid at an approximate highest working pressure is introduced into this gap 4 in order to expand the roll 2a except the middle solid part from inside. Under this condition, the roll 2a is finished up by grinding so as to have the outer surface in a straight cylinder shape and both end parts in a slightly tapered shape. At working in a rolling process, the gap of work rolls is adjusted correspondingly to the shape of a material to be rolled, and then, a required pressure corresponding to the breadth of the material to be rolled is imparted to the gap 4, and the straight cylinder part of the outer surface of the roll 2a is placed under a proper condition; then, the rolling process is carried out.
