PURPOSE:To easily and always stably perform supporting work rolls and controlling shapes by forming the bearing blocks of split rolls to be exchanged and fitted according to the diameters of the work rolls to enable inserting into thrust blocks of split rolls and fitting and supporting them by sharing guides. CONSTITUTION:Intermediate rolls 7, 7' and large diameter work rolls 18, 18' supported by these are disposed between upper and lower stay rolls 1, 1'. Furthermore, the rolls 18, 18' are supported capable of horizontal bending by the split rolls 13, 13' through single supporting rolls 19, 19'. At the time of exchanging the work rolls, the upper and lower rolls supporting blocks 4, 4' incorporating each roll are opened by operating a clearance adjusting device 2 and the rolls 19, 19' are detached together with the rolls 18, 18' and the bearing block 22. Then, the minimum diameter work roll (figure is omitted) is set and the large diameter supporting roll making the rolls 7, 7' to support it is set together with its bearing block. This bearing block is inserted and supported sharing with the guide 23 of the thrust block. |
