摘要： PURPOSE:To eliminate undesirable rolling due to meandering and to obtain a rolled product of high quality by attaching a bending-force providing means adjacently to a take-up roll and preventing the meandering of a rolling stock perfectly and easily. CONSTITUTION:The revolving axes 20, 21 of take up rolls 17, 18 are supported by bearings 22, 22, and further bearing boxes 23, 23 are attached to the axes 20, 21 at the outsides of bearings 22, 22 by allowing the axes 20, 21 to penetrate through the boxes 23, 23, and hydraulic cylinder devices 24, 24 and rod parts 24a, 24a are preferably connected to the boxes 23, 23 as the bending means of axes 20, 21. When the meandering of a rolling stock 19 is generated, the actuated forces of devices 24, 24 are transmitted to the rolls 17, 18 through the boxes 23, 23 to provide proper bendings to the rolls 17, 18. By this construction, the tension of stock 19 can be made ununiformed in its width direction, and the stock 19 is moved to the smaller tension side; therefore the meandering of stock 19 is easily prevented by conforming its moving direction to the correcting direction of meandering through said mechanism.
摘要翻译：目的：为了消除由于蜿蜒而引起的不希望的滚动，并且通过将弯曲力提供装置相邻地附接到卷取辊来获得高质量的轧制产品，并且能够完美且容易地防止机动车辆的蜿蜒曲折。构成：卷取辊17,18的旋转轴20,21由轴承22,22支撑，并且另外的轴承箱23,23通过允许轴线22,22在轴承22,22的外侧附接到轴线20,21。 20,21穿过盒23,23，液压缸装置24,24和杆部24a，24a优选地连接到作为轴线20,21的弯曲装置的箱23,23。当轧制的曲折产生储存件19，装置24,24的致动力通过箱23,23传递到辊17,18，以向辊17,18提供适当的弯曲。通过这种结构，可以制成坯料19的张力在宽度方向上不均匀，坯料19移动到较小的张力侧; 因此，通过使其移动方向与通过所述机构的曲折的校正方向一致，容易防止库存19的曲折。

CONSTITUTION:A detected sheet thickness H1X is outputted by a delay circuit 21 as an estimated value H1M of sheet thickness at the inlet side of the 1st pass, and an arithmetic circuit 22 of outlet side sheet thickness computes as estimated value h1M of sheet thickness at the outlet side of the 1st pass, and a delay circuit 23 outputs an estimated value H2M of sheet of sheet thickness at the inlet side of the 2nd pass. An outlet-side sheet-thickness arithmetic circuit 24 computes in the same way an estimated value h2M of sheet thickness at the outlet side of the 2nd pass, and computes also an estimated value h3M of sheet thickness at the outlet side of the final pass. Next, an arithmetic device 30 computes the deviation between a target value h3R and a detected sheet thickness h3X, and outputs a correction signal DELTAh3R to add it to an arithmetic device 40. The device 40 adds the value, obtained by correcting the deviation between the values h3R and h3M by the signal DELTAh3R, to arithmetic circuits 41, 42, and the circuit 41 computes a target correcting quantity DELTAS of total draft positions, and the circuit 42 computes a target value correcting quantity V3 of roll speed. A changeover switch 43 adds the correcting quantity DELTAS or DELTAV3 to a rolling reduction controlling device.

摘要： PURPOSE:To manufacture stably a steel sheet having a uniform sheet thickness by housing each roll chock of upper and lower rolls in a main housing of a multisage multipass rolling mill and housing each roll chock of intermediate rolls in a subhousing supported by the main housing. CONSTITUTION:In case of rolling a steel sheet 1 by a multistage multipass mill consisting of upper and lower rolls 2, 3 and intermediate rolls 4, 4; a roll chock 5 of the upper roll 2 is supported by a main housing 10 through a rolling-reduction screw 7, and a chock 6 of the lower roll 3 is supported by the housing 10 through a hydraulic cylinder 9, and a balancing cylinder 11 is interposed between both chocks 5, 6. Each of roll chocks 12, 13 of the upper and lower intermediate rolls 4, 4 is also supported by a subhousing 16 through a rolling-reduction screw 14 and a hydraulic cylinder 15. The subhousing 16 is fixed to the main housing 10 through connecting members 17, 18. Because each of the chocks 5, 6, 12, 13 is directly supported at its upper and lower parts by the rolling-reduction screw and the hydraulic cylinder, the sheet position is not deviated even when a rolling force fluctuates, and a steel sheet of uniform sheet thickness is stably manufactured.

摘要： PURPOSE:To prevent the meandering of a rolling material with a multi-passes rolling mill having >=3 pieces of work rolls rotating at different speeds in one stand by detecting the roll gaps on the operation side and driving side of at least one pass and controlling the respective gaps to target values. CONSTITUTION:The rolling material S is passed through the roll gaps 15-17 formed of the work rolls 8 and 9, 9 and 10, 10 and 11 and is thereby rolled in the stage of rolling the material S in the multi-passes rolling stand having the work rolls 8-11 and backup rolls 7, 12. The output signals from displacement gapes 21a, 21b attached to roll chocks 3a, 3b of the work roll 9 are fed to a relational calculator 22. The signals therefrom are compared with the output from a target value setting circuit 25 constituted of a relay 23 and a storage circuit 24 by a relational calculator 26. The resultant parallelism deviation signal is inputted to a parallelism control adjuster 27 by the output signal of which the roll gaps on the right and left operation side and driving side of the roll gap 15 are controlled and the meandering of the material S is prevented.

The base metal S existing between the two rolling passes in the mid-way of the passage is so wound around the 1st and 2nd draw-out rolls 7, 8 respectively as to be detached from the 2nd, 3rd work rolls 2, 3. The clad ding metal A which constitutes one side of the clad steel plate C is supplied to the 2nd pass by the 1st payoff roll 10 and the cladding material B which constitutes the other side is supplied to the 3rd pass by the 2nd payoff roll 11. The cladding metal A supplied to the 2nd pass is rolled down in the 2nd and the 3rd passes and the cladding metal B supplied to the 3rd pass is rolled down in the 3rd pass, respectively together with the base metal S at a high draft by which the cladding metals and the base metal are joined to constitute the clad steel plate C.
