摘要： PURPOSE:To reduce rolling driving power by making one of a pair of roll driving rolling be non-driving. CONSTITUTION:A hydraulic unit 13 is operated and a clutch moving gear 8 is intermeshed with a clutch fixing gear 10 by way of a lever 12. Then, the pinion 11 which is supported by a bearing 14 to the upper output shaft 9 connected to an upper spindle 2A by the clutch moving bear 8 is fixed to the clutch fixing gear 10. And the driving power of a motor 3 is transmitted by way of a lower pinion 5 to the pinion 11, whereby two roll driving rolling is accomplished. When the clutch moving gear 8 and clutch fixing gear 10 are disconnected by the lever 12, one roll driving rolling is accomplished.

摘要： PURPOSE:To control the quality of sheet during rolling by proving heating devices with which a sheet is heated on the inlet and outlet side of a rolling mill, providing them in a tightly sealable container and enclosing inert gas in the container. CONSTITUTION:In a rolling equipment, the sheet 13 is rolled with a rolling mill 4 and is coiled with coilers 5. Then, the heating devices 2 with which the sheet 3 is heated are provided on the inlet side or outlet side or both sides of the rolling mill 4. And those devices are provided in the tightly sealable container 1. Inert gas 6 is enclosed in the container 1. Cooling devices with which the sheet is cooled are provided on the inlet or outlet side or both sides of the rolling mill. The heating system is taken as a high frequency heating system. Thereby, the rolling of very thin material or high hard material can be stably and easily performed.

摘要： PURPOSE:To allow shape control of the higher order and to provide the compact rolling equipment by providing an axial symmetrical space in the inside on one side in the barrel part of the rolling roll to constitute the barrel part of the rolling roll in such a manner that the geometrical moment of inertial thereof varies in the axial direction. CONSTITUTION:The axial symmetrical space is provided in the inside on one side in the barrel part of the rolling roll 5 to constitute the barrel part of the rolling roll in such a manner that the geometrical moment of inertia thereof varies in the axial direction. Different deflection curves are, therefore, obtd. in the axial direction by imparting bending force to the rolling roll 5. The sheet crown and shape control of the higher order is executed in this way. In addition, the plural deflection curves are formable with one piece of the rolling roll. The compact rolling equipment is thus obtd. and the cost is reduced.

摘要： PURPOSE:To decrease the number of coiling reels and to reduce an equipment cost by superposing at least two sheets of plate materials which are different in plate thickness and simultaneously rolling these materials. CONSTITUTION:A looper 13 inclines leftward when the speed of the thin plate material 1 decreases to the speed lower than the speed of the thick plate material 2 at the time when the thin plate material 1 and the thick plate material 2 are superposed and are rolled by a rolling mill. The negative speed is detected by a rotating speed detector 19. A computer 21 makes judgment that the speed of the thin plate material 1 is lower. Then, the computer commands a control panel 23 of a motor 17 for a tensioner 11 to increase the speed and a control panel 25 of a motor 15 of the reel 9 to lower the speed, respectively. On the other hand, the thin plate material 1 slackens when the inflow speed of the material 1 to the rolling mill lowers on the inlet side of the rolling mill. Then, the looper 14 rotates leftward and this rotation is detected as a negative speed by a rotating speed detector 20. The command is emitted to the control panel 24 of a motor 18 of a tensioner 12 so as to increase the speed and the command is simultaneously outputted to the control panel of a motor 16 of the reel 10 so as to lower the speed.
