Abstract

PURPOSE:To reduce rolling force and to improve the effect of shape controlling by making one of upper and lower work rolls smaller in diameter and disposing a horizontal bending device for the small diameter work roll on the deviating side. CONSTITUTION:A cylinder 12 is operated to move and adjust a wedge 13, a movable plate 9, a shaft 7, and a stay roll 8 respectively separately, whereby the rate of deflection of a lower work roll 4 is adjusted freely. At this time, when the roll 8 is pressed strongly to the roll 4, the clearance between the roll 4 and an upper work roll 3 in said part is reduced and the thickness of a rolling material S is decreased. Further, the roll 4 is formed to a smaller diameter and therefore, the roll 3 can apply powerful perpendicular bending force to an intermediate roll 5, whereby the shape controlling is accomplished with good accuracy.
