摘要： PURPOSE:To shorten waiting time and to reduce variance in cutting dimensions caused by difference in temperature, in the case of reverse rolling one by one through plural passes and also the case of cutting operation for plural pieces together. CONSTITUTION:In the case of three-pass rolling and cutting of two pieces of rolling stock, a first rolling stock W1 is provided with a one-way rolling process A from a rolling line on the entrance side to rolling, to a rolling line on the exit side and to a standby; then, a second rolling stock W2 is provided with a round trip rolling process B from the rolling line on the entrance side to rolling, to the rolling line on the exit side, to rolling, to the rolling line on the entrance side and to a standby. In addition, after the first rolling stock W1 is provided with the round trip rolling process B, the second rolling stock W2 is provided with the one-way rolling process A, taken out together with the first rolling stock W1 and cut. Thus, a waiting time for the first rolling stock is greatly shortened.

摘要： PURPOSE:To reduce the number of steps of finish rolling, and to reduce the number of finish mills installed on a pass line by performing reverse rolling to a stock to be rolled, and performing reverse rolling for finishing to a rough rolling plate, while holding the obtained rough rolling plate at a prescribed temperature. CONSTITUTION:For instance, a rough rolling plate whose thickness is 80mm becomes a rolled stock whose thickness is 40mm after finish rolling is performed by a finish rolling mill 22, and its rolling plate becomes a rolling plate whose thickness is 10mm after finish rolling is performed by the finish rolling mill 22 again. This rolled plate is wound round by a heat insulation coil box 21 and stored temporarily in the heat insulation coil box 21 in a state that it is held at a prescribed temperature. Thereafter, the rolled material is wound out of the box 21 and finish rolling is performed thereto by the finish rolling mill 22 again, and it becomes a sheet whose thickness is 1.5-2mm, and coiled to a coiling roll 8. Reverse rolling is performed to a slab, and while holding the obtained rough rolling plate at a prescribed temperature, reverse rolling for finishing is performed to the rough rolled plate, therefore, a thin rough rolled plate can be subjected to finish rolling.

摘要： PURPOSE:To improve the working efficiency and automate schedule optimization process by optimizing a pass schedule even when rolling stocks which are divided into plural regions of the different number of rolling pass are rolled. CONSTITUTION:The number of pass in all the regions is unified into odd number or even number of times by inserting an unloaded pass and the schedules are arranged in order from a first pass. When the number of total passes is odd number of times and the number of effective rolling pass in the region that is previously finished is more, the final pass or the like in each region is arranged in the same pass position by adjusting the schedule in the region that the number of pass is less. When the number of the total pass is odd number of times and the number of effective rolling pass in the region that is previously finished is less, the final pass and the pass of the preceding stage or the like in each region are arranged in the same pass position by adjusting the schedule in the region that the number of rolling pass is less.

摘要： PURPOSE:To reduce the number of rolling passes and to roll easily a hard-to- work rolling stock, by providing a pair of upper and lower large-diameter work rolls, shiftable mutually reversely in their axial directions, and small- diameter work rolls changeable to the larger ones. CONSTITUTION:In case of changing work rolls from small-diameter work rolls 1 to large-diameter work rolls 2; after separating the front end of the piston rod of a hydraulic cylinder 24 from roll chocks 20, the chocks 20 are rotated to the stand-by positions by rotating a pinion, to support the chocks 20 by beams 10. The roll 1 is placed at the side of the roll 2, and the roll 2 is lowered together with a backup roll 4 by actuating hydraulic cylinders 14. The large- diameter work rolls 2, 3 are pressed against the backup rolls 4, 5 by actuating the hydraulic cylinders 14, 15. The gap between the rolls 2, 3 is set to the prescribed gap, and the rolls 2, 3 are provided with a roll bending to perform rolling.
