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： A lubricant is supplied from headers (38) of lubricant supply units (5) onto surfaces of back-up rolls (3) at locations spaced from contact positions between a pair of work rolls (2) and a pair of back-up rolls (3). The headers (38) each include a lubricant spray nozzle (41) for spraying the lubricant under a pressure not lower than 3 kg/cm , a header cover (42) for confining the lubricant sprayed from the lubricant spray nozzle (41), an oil return line (44) for returning the surplus lubricant, and seal members (43) made of flexible material such as rubber. The work rolls (2) are provided with water wiping plates (6), and the back-up rolls (3) are also provided with water wiping plates (7). In a work rolls crossing type mill thus arranged, water films of cooling water deposited on the roll surfaces are removed to prevent the cooling water from mixing into the lubricant. Even if the water films are not totally removed, it is possible to surely plate out the lubricant for reliably lubricating between the work rolls (2) and the back-up rolls (3). Raw lubricant oil of the lubricant meets the following requirements; (a) the coefficient of friction between said work rolls (2) and said back-up rolls (3) is in the range of 0.04 to 0.1, (b) the viscosity is not larger than 80 Cst. at 40 DEG C, (c) mineral oil and synthetic ester not less than 5 % are contained as base oil, (d) a fatty acid in the range of 0.03 to 0.5 % is contained as an oiliness enhancer, (e) an extreme pressure additive not less than 0.1 % is contained, and preferably, (f) a surface active agent not larger than 0.5 % is contained as emulsifier.

摘要： A rolling mill for rolling metal strip (11) moving in a horizontal rolling direction, has work rolls (1) which engage the strip and are supported vertically by backup rolls (2) through which drive is applied. The work rolls (1) are supported in the horizontal rolling direction by support rollers (4) contacting them at locations confined to intermediate regions between the work regions and bearings (8). The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means (5,7) for the support rollers operable to move and locate the support rollers so as to shift the work rolls (1) to a predetermined location at which the vertical axial plane of the work rolls (1) is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls (2). The support rollers (4) maintain the work rolls at the predetermined location during rolling.
