    • A rolling mill has a work roll and a back-up roll for supporting the work roll vertically and driving it. A plurality of horizontal support rollers contact the work roll at barrel diameter outside the rolling region and at a both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal rolling forces. In order to reduce the bending of the work roll during rolling, there are provided means for applying horizontal counterbending forces to the work roll comprising members e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers and actuator means for urging the members against the work roll. The counterbending forces being in the same direction as the net horizontal force applied to said work roll by said back-up roll and the material being rolled. Preferably at least one condition of said work roll is sensed during rolling, and there are control means acting during rolling to control the counterbending forces in dependence on the sensed condition.
    • 轧机具有工作辊和支撑辊,用于垂直地支撑工作辊并将其驱动。 多个水平支撑辊在滚动区域外侧和工作辊的两个水平边缘处以筒体直径接触工作辊,并且用于在轧制期间在两个水平方向上固定工作辊的位置并且抵抗水平轧制力。 为了减少轧制过程中的工作辊的弯曲,提供了用于将水平的反作用力施加到包括构件的工作辊的装置。 辊子,在与滚动区域相比轴向更远的位置处的工作辊与支撑辊和致动器装置接触,用于将构件推向工作辊。 所述反作用力与由所述支承辊和被轧制材料施加到所述工作辊的净水平力处于相同的方向。 优选地,在轧制期间感测到所述工作轧辊的至少一个状态,并且存在在轧制期间作用的控制装置,以根据感测到的状况来控制平衡力。

    • In a rolling mill comprising upper and lower work rolls crossed each other to perform strip crown control, a straight line connecting the center of an operation side screwdown screw and the center of a drive side screwdown screw is inclined relative to a line perpendicular to the rolling direction. A cross angle .theta. to be controlled is changed in opposite plus and minus directions about the straight line connecting both the screwdown centers. A large extent of strip crown control can be achieved with a smaller cross deviation than usual in the prior art, thereby permitting omission of an equalizer beam. Further, change in the extent by which strip crown is varied upon control with respect to the cross angle becomes substantially linear and hence control is more easily conducted. Since the cross angle 2.theta. between the two work rolls is larger than 2.degree., the transition temperature is not changed and uniformity in quality can be ensured.
    • 在包括相互交叉的上下工作辊的轧机中进行钢带冠控制,连接操作侧拧紧螺钉的中心和驱动侧拧紧螺钉的中心的直线相对于垂直于轧制的线倾斜 方向。 要控制的十字角θ围绕连接两个拧紧中心的直线以相反的正负方向改变。 可以在现有技术中以比通常更小的交叉偏差实现大范围的带状凸肩控制,从而允许省略均衡器梁。 此外,在相对于十字角度的控制下,条形凸起变化的程度的变化基本上是线性的,因此更容易进行控制。 由于两个工作辊之间的交叉角2θ大于2°,所以转变温度不变,可以确保质量的均匀性。

    • A rolling mill comprises a pair of an upper and a lower work roll having a small diameter which is as large as about 0.15 to 0.30 times the width of a metal sheet article to be rolled, a pair of an upper and a lower back-up roll, a pair of an upper and a lower intermediate roll disposed intermediate between the work roll pair and the back-up roll pair, work roll bending units and intermediate roll bending units imparting bending forces to the roll ends of the upper and lower work rolls and/or the roll ends of the upper and lower intermediate rolls respectively, roll shifting units capable of shifting the upper and lower intermediate rolls in axial directions opposite to each other, and drive units coupled to the associated ends of the upper and lower intermediate rolls to rotate the upper and lower work rolls at different peripheral speeds through the intermediate rolls. The directions of roll bending by the work roll bending units and/or the intermediate roll bending units and the relative movement of the body ends of the intermediate rolls relative to the widthwise ends of the sheet article caused by the roll shifting units are controlled thereby forming slight edge waves in the widthwise edge regions of the sheet article, so that, even when a high tension is applied to the sheet article during rolling with a high reduction ratio, occurrence of cracks in the widthwise ends of the sheet article is minimized to prevent breakage of the sheet article.
