摘要： PURPOSE:To make the distribution of thickness in the width direction of a strip effectively adjustable and to control properly a passing position in the width direction to a rolling mill, by passing a continuously running strip to be rolled through a tension generating device consisting of an upper roll and two lower rolls located at the inlet side of the mill. CONSTITUTION:In feeding a strip S such as a steel strip, the distribution of its tension in its width direction is adjusted by passing it through a tension generating device located at the inlet side of a rolling mill to control the passing position of strip S in its width direction. The tension control device is constituted of an upper roll 3 and two lower rolls 1, 2, and the rolls 1, 2 are fixed to a lower frame 4 and the roll 3 is fixed to an upper frame 5 through bearings. The distance between the roll 3 and the rolls 1, 2 is changed by the vertical movement of another upper frame 6 to which the roll 3 is fixed through a pin 8, and the movement is produced by a pinion 11 and a rack 10 which are driven by actuating a cylinder 9; the uniform distribution of tension in the width direction is given to the running strip S to pass it at the right position with respect to the rolling mill.

摘要： PURPOSE:To obtain a titled device capable of measuring the tension of a material accurately and detecting the meandering even if its quantity is small by constituting the device wherein the load of a roll is received by load cells disposed at the inside of bearing parts through a frame which connnects the bearing parts located at both sides of the roll. CONSTITUTION:A tension meter device of a rolling mill is constituted by pivotally supporting a bracket 13 attached to a frame 10 which connnects roll chocks 3, 3 located at both sides of a roll 2 of rolling mill, and a bracket 15 on a fixed frame 16, at the position just below a pass center C, and installing a pair of load cells 1, 1 at both sides of the center C and at the inside of said chocks 3, 3. By said device, the tension of a material to be rolled is accurately detected by receiving a load loaded from the material 8 on the roll 2 by the load cells, 1, 1 and also even the small quantity of material meandering is detected basing on the difference between the loads of load cells 1, 1 located at both sides when the material 8 deviates from the pass center C and meanders.

摘要： PURPOSE:To enable various rearranging patterns by providing respectively rails to be exclusively used to work rolls and intermediate rolls to assure space and providing a moving machanism to be commonly used. CONSTITUTION:Rolls 6, 7 are removed by a push puller 13 in the case of rearranging upper and lower work rolls 6, 7. The position of a side shifting table is then side-shifted. The engagement between the push puller 13 and upper and lower intermediate rolls 5, 8 is released, and the puller 13 is inserted into a rolling mill 1 by means of cylinders 14, 15. The puller 13 can force the fresh upper and lower work rolls 6, 7 into the mill 1 without contact with the rolls 5, 8. An oil pressure is finally applied on the hook cylinder to remove an upper work roll hook 16 and a lower work roll hook 17 from the roll 6 and the roll 7 respectively and the cylinders 14, 15 are contracted to return the puller 13 to the home position. The roll rearrangement is thus completed.

摘要： PURPOSE:To make zero the clearance between a roll bearing box and housing with the smaller force and to improve the life of the bearing box by interlocking the output of a clatter-eliminating cylinder which makes zero said clearance to the output of a roll bending cylinder. CONSTITUTION:A piston 16 is movably incorporated freely forward and backward into the clatter-eliminating cylinder 12 and the oil entering the cylinder through an oil forde-feed port 17 pushes the piston 16 out of a chamber 18. Then the bearing box 6 is pressed to the other housing window 2' side by right and left blocks 9, 10 and the bearing box 6 and is surely bixed in a stand. An oil feed port 14 of the roll bending cylinder 11 and the oil port 17 of the cylinder 12 are communicated with each other at a branch point 19 so that always the same pressure is exerted thereto. The force exerted to the cylinder 12 increases as well when the force exerted to the cylinder 11 increases during rolling. The same holds true of the case in which the force decreases. More specifically, there is not need for exerting more than the necessary force to the cylinder 12. The life of the bearing box 6 and the block 9 is thus extended.
摘要翻译：目的：使用较小的力量使滚动轴承箱和壳体之间的间隙为零，并通过将使所述间隙为零的所述间隙的输出互锁到辊弯曲缸的输出来提高轴承箱的寿命。构成：活塞16可自由地前后自由地并入排气筒12，通过供油口17进入气缸的油将活塞16推出室18.然后将轴承箱6按压通过左右块体9,10和轴承箱6到另一个壳体窗2'侧，并可靠地固定在支架中。辊弯曲缸11的供油口14和气缸12的油口17在分支点19处彼此连通，从而始终施加相同的压力。当施加到气缸11的力在轧制期间增加时，施加到气缸12的力也增加。在力减小的情况下也是如此。更具体地，不需要向缸12施加超过必要的力。因此，轴承箱6和块9的寿命延长。

CONSTITUTION:Both sides of a plate 11 for moving a bearing case 3 containing a roll 1 in the longitudinal direction of the roll 1 are attached to a link 14 and a link 15 by a pin 13. Also, the link 14 and the link 15 are supported by a support 22 at the opposite side of the pin 13 so that the link 14 and the link 15 become parallel. Moreover, the support 22 is held by a bracket 16 fixed to a housing 2. Also, one end of the link 14 and 15 is connected to a cylinder 17, and the cylinder 17 is held by the bracket 16 with a pin 18. Accordingly, the bearing case 3 is moved by expansion and contraction of the cylinder 17.
