摘要： PURPOSE:To prevent the center of a roll from being shifted to the direction of a roll axis by providing projecting parts to the outside end of a roll chock, and connecting them eccentrically and freely rotatably to the roll. CONSTITUTION:When a roll 6 is slanted, the roll 6 and a roll chock 3a are moved in circular-arcuate motion in the same direction, and sliders 21a, 21b are moved straightly while following crank plates 19. Eccentric rolls 22a, 22c inserted into the sliders 21a, 21b are moved also in the same direction. By said movements, eccentric axes of the rolls 22a, 22b are rotated eccentrically with radii corresponding to the extent of eccentricity and are moved on the circular circumference of a radius with a roll cross point as a center while following projecting parts 20a, 20b of the chock 3a. Accordingly the roll 6 and the chock 3a are not subjected to a force in the direction of the roll axis, then the slide abrasion at the bearing surfaces between upper and lower chocks and roll bending cylinders are prevented and the power for driving respective cross rolls is reduced.

摘要： PURPOSE:To easily set the parallel position of two work rolls, by utilizing that a moving speed in the axial direction of roll and a thrusting force are proportional to a crossing angle formed by two roll axes, in a roll-cross type rolling mill. CONSTITUTION:Mutually crossing rolls of a roll-cross type mill are rotated, and a thrusting force or a roll chock speed is detected between a roll chock at one side and a thrust clamp; the central position between two zero points of thrusting force obtained by crossing two rolls to one direction or to the reverse direction in the contacting surface, between the two rolls, by a roll-crossing device, or the central position between two zero points of roll-chock speed is made as the parallel position of heads of the roll-crossing device. In ordinary rolling, the heads of the roll-crossing device are set as the parallel position according to the position where respective rolls stabilize, or are set by shifting the head at one side from the parallel position by a gap portion between the head and the roll chock.

摘要： PURPOSE:To control the crooked running of a rolling material by vertically changing the position of the rolling material before and after a rolling mill, and changing the angle at which the rolling material wraps on rolls, in a roll cross type rolling mill. CONSTITUTION:A rolling material 5 passes through pinch rolls 4 then through crooked running detectors 6 and is rolled by a roll cross type rolling mill 1 which rolls the material with work rolls 2a, 2b and backup rolls 3 crossed in a pair, thence the material is fed to the next process. When the rolling material runs crooked at this time, the detectors 6 emit signals. The signals are inputted to a control circuit which moves the pinch rolls 4 upward and downward thereby moving the rolling material up and down. Hence, the angle at which the rolling material wraps on the rolling rolls changes, and the contact areas with the roll change, whereby thrusts are acted and the crooked running is prevented.

摘要： PURPOSE:To diminish the damage of a bearing by bearing a work roll chock with an intermediate roll outer chock and aligning the position of the work roll balance with the central position of work roll bearing. CONSTITUTION:The shaft end of the work roll 1 is supported by the work roll chock 11. The intermediate roll 2 is supported by an intermediate roll outer chock 12 and the work roll 1 is pressed and supported by a reinforcing roll through this intermediate roll. Then, the work roll chock 11 is born by the intermediate roll outer chock 12 through a work roll balance 13. The installed position of the work roll balance 13 and the central position in the axial direction of a work roll bearing supporting the axial end of the work roll 1 in the work roll chock 11 are nearly aligned. In this way, a deviated moment can be prevented from acting on the work roll bearing.

摘要： PURPOSE:To synchronously push out or draw back roll chocks of the same quantity to easily control the thickness shape in the direction of sheet width, by providing a driving mechanism exerting pressing forces in the direction of rolling from both sides of at least one side of roll chocks. CONSTITUTION:Worm jacks 13a-13d and 13a'-13d' are driven by electric motors 31 and 131 provided to upper both ends of a rolling mill through a coupling 32, a reducing gear 33, and bevel gears 35, and 35b.Hereupon, shafts 36a and 36b of a shaft system connected to input shafts of the worm jacks on the operation side are both rotated in one direction, but the worm jacks 13a, 13b and 13c', 13d' act in the stretching direction of the whole length of the jack, and 13c, 13d, and 13a', 13b' act in the shortening direction of the whole length of the jack. Accordingly, on the operation side, lower roll chocks move to the right side when upper roll chocks move to the left side. On the other hand, on the driving side, a roll cross is obtained by moving upper roll chocks to the right side and lower roll chocks to the left, because a retaining device of roll chocks on the driving side is made to act in the reverse direction to the acting direction of the retaining device on the driving side.

摘要： PURPOSE:To prevent the rolled stock from meandering by making one side work roll to a little diameter, adjusting each position of rolling reduction of plural divided small rolls composed of the back-up roll independently and controlling the bent. CONSTITUTION:The rolling is executed with a work roll of a small diameter 2 and a work roll of a large diameter 8. The side reinforcing rolls 5, 6 are made to the composition of plural divided small rolls 101-105, and made to be able to adjust each position of rolling reduction. By detecting the meandering or the camber with the detector 19, inputting the result to the caluculating unit 20, outputting the result to the division BUR controller 21 and to the bender controller 22, the position of the devided small rolls 101-105 are controlled. The camber and the meadering can be prevented by controlling the position of the divided small rolls of BUR of the cluster mill and to intly utilizing the roll bending.

摘要： PURPOSE:To reduce remarkably the unbalance of a rolling down force by forming the roll chock of a cross-roll mill by a radial roll chock for receiving a radial load and a thrust chock for receiving a thrust load. CONSTITUTION:The journal 8a of a backup roll 8 which is in contact with a work roll 2 is supported by a radial chock 101 through a radial bearing 9, the journal 8b of backup roll 8 is supported by a thrust chock 102 through a thrust bearing 11, the chock 101 and the chock 102 are joined together by through bolts 103 through a positioning spacer 104, and a clearance 8 is set by springs 107, 108. Further, the chock 101 acts on the roll 2 to transmit a rolling load transmitted to the roll 8 to rolling reduction screws 10; on the other hand, the chock 102 transmits a thrust to chock clamps. In this way, the unbalance of a rolling down force is remarkably reduced, and its sheet thickness control is easily performed.
