Abstract
PURPOSE:To economically manufacture the product strip with high dimensional accuracy and excellent shape, by rolling the material under the condition that the centers of the inner work rolls are shifted from the center line connecting the centers of the outer work rolls, and by adjusting the pressure of the liquid to be supplied to the internal cavity of the backup roll. CONSTITUTION:The center A of the inner work roll 6 located on the feed-in side is shifted to the run-out side from the center line l connecting the centers O, O of the outer work rolls 8, 9, and the center B of another inner work roll 7 located on the run-out side is shifted to the feed-in side from the center line l; under this condition, the material S is rolled while being given the tensions T1, T2. At the same time, the pressure liquid is supplied to the cavity 15 of the backup rolls 11, 12 through the liquid pipe 17, the pipe joint 18 and the liquid pathway 16; hereupon, the cavity 15 is being formed in a ring type within the body of each of backup rolls 11, 12 near the outer surface of the backup rolls 11, 12, so as to make the central shaft of the ring cavity 15 to coincide with the shaft (r) of the backup roll 11, (12). Hereby, the outer shell 19 of the backup roll 11, (12) causes an elastic deformation, correspondingly to the liquid pressure given to the cavity 15, into a barrel shape, and a required roll crown C is formed. It is also possible to form the required roll crown C by adjusting the heat-output of the heating source supplied to the cavity 15.
