Abstract
PURPOSE:To reduce the rolling load, and to make the high draft rolling work possible, by shifting the center of the inner work roll in the direction opposite to the tension acting on the material passing the rolling pass, and by loosely fitting the sleeve to the backup roll. CONSTITUTION:In respect of the center line of the outer work rolls 8, 9, the center A of the inner work roll 6 is shifted to the run-out side, and the center B of the inner work roll 7 is shifted to the feed-in side. Hereby, the centers A, B, of the inner work rolls 6, 7, are shifted in the direction opposite to the tensions T1, T2, acting on the material S. During the material S is rolled by the rolls, the feed-in side inner work roll 6 is attracted toward the feed-in side, and the run-out side inner work roll 7 is attracted toward the run-out side, because of above stated offset of the roll centers, and the outer work rolls 8, 9, are also horizontally held through the material S; hereby, the roll does not cause the horizontal distortion during the rolling work. Moreover, if the sleeves 15, 16, freely rotatable, and freely movable in the direction of the roll axis, are loosely fitted to the outer surface of the backup rolls 10, 11, the better effect is attained.
