摘要： In a rolling mill in which hydraulic apparatus (12;13), for controlling the roll balance or the shape of the rolled material are incorporated in movable frames (10;11) provided separately from roll chocks (4;5) mounted at each end of the rolls (1,2), reducing the roll inclination thereby making it possible to carry out stable rolling, and also reducing the roll vibrations, and making it possible to manufacture products with a high quality. Providing hydraulic apparatus (12 and 13) for controlling the roll balance and the shape of the rolled material inside the movable frames (10 and 11), hydraulic apparatus (16 and 17) that push and restrict the roll chocks (4 and 5) and the movable frames (10 and 11) in the direction of flow of the rolled material relative to the roller stand (3), and the hydraulic apparatus (18 and 19) that push and restrict the movable frames (10 and 11) in the up/down direction relative to the roller stand (3).

摘要： In addition to the usual type of screw-down mechanism (34, 35), work roll gap is adjusted during work roll change for different diameter work rolls (4, 5), without removing the backup rolls (2, 3), by a variable height plate rotatably inserted between the backup roll chocks and the housing (1), which will minimize the volume of oil contained within the screw-down adjustment rams (22, 32) while maintaining good rigidity for the plate adjustment (H) even during high impact and high vibration hot rolling. A similar effect is provided by containing unused plate height portions entirely within the footprint of the housing where they can be rigidly supported. Further rigidity is obtained with minimizing the volume of fluid within the rams, accomplished by placing the valve stand immediately adjacent to the hydraulic rams for the screw-down and preferably on top of the housing. The roll change height adjustment provided by the plates, as opposed to a bulky screw-type adjustment, provides for a reduced height housing and the additional room for the valve stand.

摘要翻译： 除了通常的拧紧机构（34,35）之外，在不同直径的工作辊（4,5）的工作辊更换期间调整工作辊间隙，而不需要移除支承辊（2,3） 可变高度板可旋转地插入在支承辊轴承座和壳体（1）之间，这将使包含在螺纹调节凸起（22,32）内的油的体积最小化，同时在板调节（H）期间即使在 高冲击和高振动热轧。 通过将未使用的板高度部分完全包含在壳体的占地面积内可以得到类似的效果，其中它们可被刚性支撑。 通过使阀座立即靠近液压柱塞以最好地在壳体的顶部放置，使得柱塞内的流体的体积最小化来获得进一步的刚性。 与大型螺旋式调节相反，由板提供的滚动变化高度调节提供了减小高度的壳体和用于阀架的附加空间。
