Abstract

PURPOSE: To contrive to make the control of hydraulic screw down mechanism easy and to shorten the working time for exchanging the rolls, by building the gap adjusting block and the hydraulic unit for supporting the chocks in the rolling mill.
CONSTITUTION: The gap adjusting blocks 9a, 9b, are installed between the chocks 5a, 5b, of the lower backup roll 3b and the push-up cylinders 2a, 2b. The movement of lower rolls 3a, 3b, for adjusting the pass line "O" are caused by vertically moving the attachment of each blocks 9a, 9b. When the rolls 3a, 3b, are to be pulled out, the chocks 5a, 5b, are slightly pushed up, and each of blocks 9a, 9b, is drawn toward center, and the blocks 9a, 9b, are pulled out of the space between the chocks 5a, 5b, and the push-up cylinders 2a, 2b. Next, the hydraulic cylinder 15 is operated to put down the blocks 9a, 9b, and the hydraulic pressure of the ram is released. Hereby, the rolls 3a, 3b, are put down by their own weight, and the chocks 5a, 5b, are put on the guide rails 6a, 6b.
