摘要： PURPOSE:To reduce or eliminate the side thrust of a work roll for performing high speed rolling and preventing the damage of bearings by crossing a backup roll and a work roll with each other, in performing the cross rolling by upper and lower work rolls. CONSTITUTION:Though a cross rolling by work rolls 1, 2 is performed for improving the accuracy of sheet thickness, side thrusts exert respectively on the rolls 1, 2 to increase the loads of bearing parts. The thrusts are dispersed by crossing respectively the work rolls 1, 2 and backup rolls 3, 4 with each other, and the thrusts exerting on the rolls 1, 2 can be offset with each other to a zero level by adjusting them. That is, when the inclination angle of the rolls 3, 4 is made smaller than the inclination angle thetaW of the work rolls 1, 2 by angle DELTAtheta, the directions of thrusts FW and FB are made reverse to each other to offset them with each other. Thus, the thrust F to a mechanism for receiving the thrust load is reduced.
摘要翻译：目的：为了减少或消除用于执行高速轧制的工作辊的侧向推力，并且通过上下工作辊进行横轧，防止轴承通过支承辊和工作辊彼此交叉而损坏轴承。构成：虽然为了提高板厚的精度而进行用工作轧辊1的横轧，但分别在辊1,2上施加侧向推力，以增加轴承部的负荷。通过将工作辊1,2和支承辊3,4彼此交叉而将推力分散，并且通过调整它们，施加在辊1,2上的推力可以彼此偏移到零水平。也就是说，当使辊3,4的倾斜角小于工件辊1,2的倾斜角度θW的角度DELTAtheta时，推力FW和FB的方向互相反向以便使它们各自偏移其他。因此，减小了用于接收推力载荷的机构的推力F.

Also, a plate thickness deviation value DELTAHi of delivery of the roll 2i-1 is detected by a plate thickness deviation detector 6. Subsequently, a forward rate of the roll 2i-1 is calculated from said detecting value by the computer 14, also a peripheral speed controlled variable DELTAHRi-1 is detected, also a shift delay time is calculated, and the control timing is decided, and the roll peripheral speed is controlled. This controlled variable is distributed to a peripheral speed of the second roll 2i, or it can be replaced with the roll 2i.

摘要： PURPOSE:To automate zero adjusting operation and to improve controllability for shapes by operating the rotating angles of eccentric sleeves provided to split backup rolls from the differences between the crowns of a plate after rolling and reference values, and changing said angles by means of servocontrol mechanisms. CONSTITUTION:In multistage cluster rolling mills, first a reference material 13 to be rolled is used and said material is rolled. The detected values of a detector 26 for plate crowns are stored as reference values in a storage device 27. When the profiles of rolls change on starting of prescribed rolling, an arithmetic device 28 for zero adjustment is operated to calculate the rotating angles of motors 24 from the differences between the detected values of the detector 26 and the reference values of the device 27. The signals thereof as control signals are outputted to a controller 29 for the rotating angles of the respective motors. The motors 24 are started by said output signals and the motors 24 are rotated by prescribed rotating angles by the outputs of a detector 25 for rotating angles and the outputs of the device 28. As a result, the angles of the eccentric sleeves 15 of split backup rolls 1, 2 are changed and the prescribed profiles of the rolls are restored.

摘要： PURPOSE:To correct the large malformation and small malformation of a strip by combining both bending forces and to improve the controlling ability of the shape of strip, by making respective small diametral work rolls and intermediate rolls exert roll bending forces independently. CONSTITUTION:The large malformation of a metallic strip is corrected by making intermediate rolls 3 exert roll bending force by means of an intermediate roll bending device 71. Further, the small malformation generating near the end parts of the strip 1 is corrected by making work rolls 2 exert roll bending force by means of a work roll bending device 81, and even a composite elongation, caused by both elongations generated in the central part and in the end parts of the strip 1, is corrected by combining both bending forces.

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.

According to this constitution, the rolling reduction can be made large, and besides, the efficient rolling work to obtain the good flatness becomes possible.

摘要： PURPOSE:To restrict the increase of the rolling load due to the reduction of the sheet thickness, and at the same time, to perform the shape straightening work, by successively decreasing the roll diameter along the traveling direction of the strip, and by giving the traveling strip the 3 degrees or larger feed-in angle, at rolling the strip being passed through pairs of large and small work rolls. CONSTITUTION:At rolling the strip S being passed through plural pairs of work rolls consisting of large and small work rolls 9, 10, 11, 12,..., etc., the diameter of these tandem arranged large and small work rolls 9, 10, 11, 12, etc., is successively decreased along the traveling direction of the strip S; the strip S, being given the 3 degrees or larger feed-in angle by the deflector rolls 29, 30, etc., is zigzag passed through these plural pairs of large and small work rolls; hereby, the rolling and straightening works are simultaneously performed. According to this method, even in case of requiring a high draft percentage, the rolling load can be reduced to a relatively small value, and besides, the strip with good flatness can be efficiently obtained by the rolling work.

摘要： PURPOSE:To permit a single rolling mill to roll various kinds of rolled material, by making interchangeable the cluster roll including a small diameter work roll with a large diameter single work roll. CONSTITUTION:When the ordinary material is to be rolled, the single work roll possessing diameter similar to that of the lower work roll is used instead of the cluster roll 2. And the driving shaft 14 is connected to the upper work roll and both upper and lower work rolls are driven to rotate and to perform the rolling work. On the other hand, when the hardly workable material is to be rolled, the lower work roll 6 is remained as the driving roll, and the upper work roll 3 is made undriven, and also its diameter is made as small as possible. Moreover, since the modulus of rigidity degrades by making small the work roll diameter, the cluster roll type constitution is employed so as to back up the small diameter work roll with plural backup rolls.
