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 facilitate controlling of the thickness shape in width directions by providing pressing members of exterting forcing pressure from both sides of the rolling direction to at least one roll chock thereby allowing the roll chock to move circularly around the roll center. CONSTITUTION:If slide blocks 15a, 15c move to the right side, slide blocks 15a', 15c' move to the left side. Roll chocks 7, 107 move horizontally respectively in opposite directions, and a roll 3 is given an inclination within a horizontal plane with respect to the center of the rolling mill. At this time, the position of the contact line between the liner 16a of a cylindrical projecting surface at the leading end of the block 15a and the plane liner 17a of the chock 7 moves from Po to Pa or Pb. Therefore, when the roll center is on the line O, the contact line is at Po, and when the roll centerline is on the line A, the contact line is at Pa. When the roll centerline is on the line B, the contact line is at Pb.

摘要： PURPOSE:To effectively practice the titled control, by applying dissimilar kinds and amounts of lubricant to a pair of an upper work roll and a rolled sheet and a pair of a lower work roll and the rolled sheet, on purpose to cause a differece between the friction factors of said two pairs of the roll and the rolled sheet. CONSTITUTION:A lubricant held in a lubricant recovery tank 22 is separated by a suitable separator 23 into a high concentration lubricant 24 and a low concentration lubricant 25. Then, the high concentration lubricant 24 is supplied by a pump 27 through a nozzle 20 to the upper surface of a rolled sheet S, and similarly, the low concentration lubricant 25 is supplied by a pump 28 through a nozzle 21 to the lower surface of the rolled sheet S. That is, the friction factors between the rolled sheet S and the work rolls 10, 15 are made different, by adjusting the concentration and feed rate of the lubricant to be supplied, so that the meandering motion of the rolled sheet S during a cross helical rolling work is eliminated.

摘要： PURPOSE:To make high screw down rolling possible and to reduce the occurrence of chamber and edge drop by incorporating a rolling mill given with a diametral difference to upper and lower rolling rolls on the upper stream side than the final stand, in a tandem type rolling mill. CONSTITUTION:One or more units of rolling mills given a diametral difference in rolling rolls are disposed on the upper stream side than the final stand of a tandem type rolling mill. A cluster roll 31 is disposed on the upper stream side of this rolling mill, and a work roll 35 of a large diameter is disposed on the down side. The cluster roll 31 is of the construction wherein a small diameter work roll 32 is supported by three backup rolls 34 by way of two intermediate rolls 33. This makes it possible to apply the tension of inlet side T1 and outlet side T2 to a rolling material S, and if necessary, to pass the rolling material S by bending the same with bending rolls 36, 37. Also, the equivalent roll diameter is decreased and rolling load is reduced.

摘要： PURPOSE:To uniformalize rolling lubricating state between a work roll and a sheet over all range in the width direction extensively by alterning a feeding angle in the width direction in accordance with a cross angle of work roll and a sheet gauge at an outlet. CONSTITUTION:A plate 3 to be rolled is fed to a pair of pinch rolls inbetween which move along the vertical plane slantingly to the center line of the width direction of the plate 3. Then, the plate 3 led out of a pinch roll 4 is sent to a pair of working rolls 1, 2 mutually crossed in a horizontal plane and thereby it is rolled. At this time, the pinch roll 4 is so moved as to equalize inserting angles theta1 and theta2 of the plate 3 to the rolls 1, 2. Similarly, work rolls are provided at the outlet of the plate and the working rolls are moved inclinedly in compliance with the cross angle and the plate thickness H2 at the outlet.

摘要： PURPOSE:To eliminate the titled meandering motion with a good responsiveness with a simple, small-sized apparatus, by turning a couple of upper and lower work rolls in the same direction in a plane parallel to the surface of a rolled sheet, while keeping an almost constant crossing angle of upper and lower work rolls during the rolling work. CONSTITUTION:At a stage before starting a rolling work, the axis 10 of an upper work roll is aligned to the axis 15 of an upper backup roll on a vertical plane, and the axis 11 of a lower work roll is aligned to the axis 16 of a lower backup roll on another vertical plane; each pair of work roll and backup roll is opposedly turned by theta/2 in a plane parallel to the surface S of a rolled sheet so as to set a crossing angle theta; after these preparations are finished, the rolling work is started. During the rolling work, if the rolled sheet causes a meandering motion because of a certain cause, only the couple of upper and lower work rolls are turned in the same direction by an angle alpha in a plane parallel to the surface S of the rolled sheet while keeping the initially set crossing angle theta as it is between the upper and lower work rolls; hereby, the meandering motion of the rolled sheet is eliminated.

摘要： PURPOSE:To roll easily to a plate of desired shape by providing a pocket on the supporting stand of a flexible roll and communicating a fluid supply hole to the pocket to form a static pressure bearing and thereby enabling thickness adjustment in the direction of width during high reduction rolling. CONSTITUTION:With rotation of a work roll 11, the first and second intermediate rolls 12, 12', oil is supplied to a pocket 15 of a flexible roll 13 by an oil supply source 50 and a supply conduit tube 21, and a static pressure bearing is formed and made rotatable freely. The rolling load can be increased by increasing supply oil pressure or increasing pressure receiving area of the pocket 15 and the flexible roll 13. The throttle part performs clearance adjustment between the pocket 15 and flexible roll 13 and also pressure adjustment. Further, the supporting stand 14 of the flexible roll 13 is made to separated type in the direction of roll axis, and adjustment of position of each supporting stand is made possible. Accordingly, deviation operation of any part of the flexible roll 13 becomes possible, and plate thickness adjustment in the direction of plate width is possible.

摘要： PURPOSE:To improve shape controlling ability with the bending effect of intermediate rolls and the projecting shape effect of split reinforcing rolls in a multiple stages cluster rolling mill by moving a pair of upper, lower work rools in mutually opposite directions in the axial direction of the rolls. CONSTITUTION:The effective ends of upper, lower work rolls 2 are moved and set to at the positions apart by certain distances from both ends accaording to a rolling material 1. While the above-described distances are changed depending upon the shape of the material 1 after the rolling, roll bending devices 10 mounted between intermediate roll metal chocks 7 and housing 9 are actuated. Since the rolls 2 are small in diameter, the parts in contact with the material 1 bend along the rolls 3, and as the positions of the reaction of rolling acting upon the rolls 2 from the rolls 3 go nearer the end parts of the material 1, the bending moment by the contact load received from the rolls 3 decreases and the bending deformation of the work rolls in the end plates of the plate is reduced. At the same time, the deformation of the work rolls near the end parts of the plate by the rolling load is corrected by crown, whereby the rolled products of good shapes are obtained.
