摘要： PURPOSE:To control the size of a sheet thickness with good accuracy by backing up and bending work rolls by the high-pressure fluid injected from backup nozzles and controlling the pressure of the high-pressure fluid. CONSTITUTION:The spacing between the upper and lower work rolls 11 and 12 is set in the stage of rolling a thin sheet 10 fed from a temp. controller B. The backup nozzles 23, 24 are also vertically moved in this stage while the spacings from the rolls 11, 12 are maintained. The work rolls 11, 12 are respectively pressurized by the backup rolls 13, 15 in the case of rolling the thin sheet 10 by the work rolls 11, 12. The high-pressure water is at the same time forced into the backup nozzles 23, 24 so that the high-pressure water is injected from injection holes 25, 28 to the rolls 11, 12 respectively. The sheet thickness size in the transverse direction of the rolled sheet 10 is measured by a sheet thickness control device and the pressure of the high-pressure water, i.e., the bending rate of the respective rolls 11, 12 is adjusted by which the size of the sheet thickness is accurately controlled.

摘要： PURPOSE:To make roll changing easy and to reduce an installation cost in a multistage rolling mill by supporting roll chock by means of slider. CONSTITUTION:The supply of the pressure oil to the hydraulic cylinder of each roll bending device 20 is stopped in the case of performing roll changing. When the stoppers 19, 21 mounted on the work side of a slider 17 are removed, the rugged parts 17b, 15a to be engaged with the slider 17 and a backup roll chock 15 are formed with a suitable clearance in a vertical direction and therefore the respective rolls 12, 14 and roll chocks 13, 15 can be put into and out from a housing 16. Since the pipings such as hydraulic hoses or the like for working the device 20 are mounted to the slider 17, there is no need for attaching or detaching the piping at each roll change and the time for the roll change is reduced.
摘要翻译：目的：通过滑块支撑滚动轴承座，使多台轧机变容易，降低安装成本。构成：在执行卷筒纸更换的情况下，停止向各辊弯曲装置20的液压缸供给压力油。当卸下安装在滑块17的工作侧上的止动件19,21时，与滑块17和支承辊轴承座15接合的凹凸部分17b，15a在垂直方向上形成合适的间隙，因此，相应的辊12,14和辊轴承座13,15可以被放入和移出壳体16.由于用于加工装置20的诸如液压软管等的管道被安装到滑块17，所以不需要附接或在每次滚动变化时分离管道，并且减少滚动变化的时间。

CONSTITUTION:Each pair of upper and lower side-frames 10 for holding roll chocks 107, 109, which support work rolls 8 and backup rolls 6, between them is mounted. A pressing means for slanting the frames 10 to displace the chocks 107, 109 in the rolling direction, is provided to a housing 1. On the other hand, the frame 10 is locked freely detachably to the chock 107, and the chock 109 is locked to the frame 10 through a hydraulic cylinder 13. Further, a stopper 18 locked freely detachably to the chock 109 is pivotally attached to the face of frame 10. Furthermore, a thrust bearing mechanism is formed between the housing 1 and the other end face of frame 10.

摘要： PURPOSE:To make a work roller and a backup roller unnecessary, and to make the titled mill small in size by injecting a high pressure fluid to both faces of the upper and the lower directions of a material to be rolled, from innumerable inject holes of opposed rolling nozzles, and executing the rolling. CONSTITUTION:A gap size of an upper rolling nozzle 12 and a lower rolling nozzle 13 is set, and subsequently, by moving finely a turning shaft, an inclined angle of a tube plate part 16 of the upper rolling nozzle 12 is adjusted so as to correspond to a necessary rolling rate. Next, salt or its mixture is raised to a high pressure by a pressurizing device, supplied to the upper rolling nozzle 12 and the lower rolling nozzle 13 and injected from the respective inject holes 14, 15. At the same time, a thin steel plate 11 whose temperature has been controlled to a comparatively high temperature is made to pass through a gap consisting of the respective tube plate parts 16, 17 of both the rolling nozzles 12, 13. The thin steel plate 11 is rolled to a necessary plate thickness size by a pressure force of a molten salt which has been injected.
