摘要： PURPOSE:To obtain a product having a beautiful surface without generating roll marks by displacing an intermediate roll having the body part length larger than the body part length of a work roll in the axial direction thereby crowing the shoulder parts of divided rolls in a backup roll. CONSTITUTION:The body part length of the intermediate roll 2 is larger than the body part length of the work roll 1. The displacement of a rolled product in the shape control thereof is therefore obviated even if the intermediate roll 2 is displaced in the axial direction thereof. The bearing boxes of the roll 2 are continuously or discretely displaced in the axial direction by a rack and pinion mechanism or fluid pressure mechanism on a sliding base. The backup roll 4 is constituted of the divided rolls 6 and the shoulder parts of the rolls 6 are crowned to an arc shape. The stress distribution is thus made uniform.

摘要： PURPOSE:To enable the easy change in the crown shape of work rolls and change in the sheet shape during rolling by providing freely rotatably an eccentric sleeve between plural divided backup rolls and a supporting shaft, and turning the eccentric sleeve thereby changing the position of the backup rolls. CONSTITUTION:A backup roll which acts rolling down force on a work roll 2 with intermediate rolls 3, 3 is divided axially. An eccentric sleeve 9 is freely rotatably provided between the divided backup rolls 4b and a supporting shaft 7 thereof. A lever 11 provided with a sector gear 10 at the end is coupled to the sleeve 9 to permit the chagne in the central position of the rolls 4b by rotating the sleeve 9. A needle bearing is further provided between the sleeve 9 and the shaft 7 so that the sleeve can be turned with small force. The crown shape of the work roll 2 is thus changeable during rolling.

摘要： PURPOSE:To prevent the slip between intermediate rolls and work rolls and to decrease the frequency of changing the rolls by disposing the shafts of the two intermediate rolls in a multistage cluster rolling mill in series, and mounting bevel gears respectively to the opposed end parts of the shafts. CONSTITUTION:Gears 15, 17 are mounted respectively to the revolving shafts 18, 19 of the two intermediate rolls 2a, 2a for work rolls in a multistage cluster rolling mill. Revolving shafts 20, 21 are provided on the outside of the driving shaft 10 of a motor 23 and gears 14, 16 are mounted thereto. The revolving shafts 18, 19 of the roll 2a are meshed with the gears 14, 16. Gears 13a, 13a are mounted to the opposed end faces of the shafts 20, 21 respectively so as to oppose thereto and four stationary shafts 11 are radially disposed between the same at a right angle to the shaft 10. A gear 12 intermeshing with both of the gears 13a, 13b is provided to constitute a differential gear mechanism. The generation of a slip in either of the intermediate rolls with respect to the work rolls is prevented by such mechanism, whereby the failure and consequent exchange of the rolls are decreased.

摘要： PURPOSE:To provide a titled rolling mill which improves the accuracy in the thickness of rolled materials and the accuracy of their shapes by operating split type eccentric rolls constituting backup rolls by means of hydraulically driving devices via eccentric rings thereby controlling the rates of eccentricity and rolling reduction of the rolls. CONSTITUTION:In multistage cluster rolling mills which roll a material 1 to be rolled by incorporating work rolls 2, intermediate rolls 3, backup rolls 4, etc. into housing 1, the rolls 4 consist of 5 pieces of eccentric rolls, and their axial centers are displaced with pinions 17, racks 18a, 18b, sector gears 19a, 19b, and eccentric rings 15 by the operation of hydraulically driving devices 16. The rolls 3 and the rolls 2 in press contact with the rolls 4 supported pivotally to stationary shafts 5a stuck to the chocks 5 are deflected by the displacement of said backup rolls, whereby their corwns are adjusted. The automatic controlling of said devices 16 is made possible by position detectors 20.

摘要： PURPOSE:To prevent the generation of edge drops and to obtain products having good shapes by using split type eccentric rolls for the backup rolls of multistage cluster rolling mills, supporting work rolls displaceably and forming crowned parts at both ends thereof. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally with the axial direction of stationary shafts 5a and the bearings of the respective split rolls are off-centered. Crowns are adjusted by the entire part of said rolls 4 to offset the medially high crowns of a plate material. Further, upper, lower work rolls 2 are moved symmetrically in an axial direction to bring the crowned parts 2a formed at both ends in the end parts of a material 1 to be rolled, thereby offsetting the irregularity in the contact deformation on the surfaces of the work rolls 2. By such mechanism the products having less generation of edge drops and edge waves are obtained.

摘要： PURPOSE:To execute rolling which scarcely has a deviation of plate thickness, by executing the rolling of a warp part of the tip of a rolling material by a different diameter roll, by a different peripheral speed and a rolling reducation for inhibiting the generation of warp, and setting them to the same peripheral speed and the regular rolling reduction after the tip is bitten by the following stand. CONSTITUTION:In a different diameter roll rolling mill having an upper work roll 2 of a small diameter and a lower work roll 3 of a large diameter, a wide gap is made to such an extent as a roll gap does not contact until immediately after the tip of a rolling material 1 is bitten and also the reduction is added when the rolling material 1 is bitten, and a difference is provided on the peripheral speed of the work rolls 2, 3, so that warp is scarcely generated in accordance with the rolling reduction in that case. Subsequently, the roll peripheral speed is set to the same speed, the rolling reduction is made higher than the regular rolling reduction, the gap is reduced, and a deviation of plate thickness in a non-tension state is decreased. After the tip of the rolling material 1 is bitten in the following rolling mill, the roll gap is returned to its regular state, and the regular rolling is executed.

摘要： PURPOSE:To efficiently control the meandering motion of a rolled strip, during a cross helical rolling work practiced by a pair of a work roll and a backup roll whose axes are parallelly arranged, by shifting the work roll in a direction of rolling the strip. CONSTITUTION:A steel strip S is rolled in a rolling direction F; a lower work roll 11 with a lower backup roll 10 and an upper work roll 16 with an upper backup roll 15 respectively makes a roll pair having parallel roll axes; hereupon, the upper roll pair and the lower roll pair cross at a mill center O-1. When a lateral thickness deviation t1-t2 is generated in the strip S by a certain cause, the lower work roll 11 is shifted in the rolling direction F in order to change the mill center from O-1 to O-2. Hereupon, the gap theta between the upper and lower rolls shows the displacement of the mill center. This displacement is compared with a previously obtained normal value, and the deviation between two values is inputted to a controller which then corrects the meandering motion of the strip S.
