摘要： A rolling stand has a support frame, a pair of small-diameter working rolls defining a workpiece nip open perpendicular to the plane and rotatable about respective horizontal, parallel, and vertically spaced axes. A pair of large-diameter backup rolls are rotatable about respective axes parallel to and vertically flanking the working-roll axes. These backup-roll axes define a vertical plane offset from the working-roll plane. In addition each backup roll bears vertically on the respective working roll and a drive counterrotates the rolls of each roll pair to draw an elongated workpiece of predetermined maximum width generally perpendicular to the planes through the nip. The working rolls are longer than the maximum workpiece width and have end portions projecting axially beyond the workpiece. The rolls are pressed vertically toward the nip to compress and deform the workpiece thereat. Respective pushing elements engage horizontally generally perpendicular to the planes against the end portions of the working rolls and respective actuators push these elements horizontally generally perpendicular to the planes against the end portions of the working rolls.

摘要： A roll stand has a frame and a pair of small-diameter and substantially parallel working rolls defining a workpiece nip. Thus a strip to be rolled passes in a horizontal upstream-to-downstream direction through the nip. Respective pairs of upper and lower upstream support levers have outer ends pivoted on the frame and inner ends downstream therefrom and respective pairs of upper and lower downstream support levers have outer ends pivoted on the frame downstream of the nip and inner ends pivoted on the inner ends of the upstream levers. Respective pairs of journal blocks mounted on the inner ends of the levers support the working rolls for rotation about substantially parallel axes flanking the nip. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls and are rotatable in the frame about substantially parallel axes flanking the working-roll axes and offset therefrom in the direction. Respective upstream and downstream vertically expansible actuators are braced between the upstream and downstream levers between the respective inner and outer ends thereof for vertically bending the working rolls.

摘要： The rolling mill comprises a plurality of working rolls and supporting rolls or a plurality of working rolls, intermediate rolls and supporting rolls. The intermediate rolls with their mounts and the slender working rolls ussed with them in six-high operation are exchangeable with or replaceable by larger thicker working rolls for two-high operation. No contact can occur between the body of a working roll and the body of the adjacent supporting roll during use as a two-high mill. In two-high operation the mount of a working roll is provided with a spacer piece engaging against the mounting member of the adjacent supporting roll. The mounts of the thicker working rolls used in two-high operation can be fitted into the guide pieces which act as guides for the mounting pieces of the intermediate rolls when the rolling mill is used as a six-high mill.

摘要： A roll stand has a frame having two sides spaced apart transversely of a workpiece travel direction and formed with throughgoing windows and a pair of vertically spaced traverses extending between the frame sides. Two outer backup rolls centered on parallel axes transverse to the direction having journal blocks vertically displaceable and guided in the windows of the frame sides. Upper and lower guide elements vertically displaceable in the windows between the outer-roll blocks carry the journal blocks of two inner backup rolls. Pairs of positioning actuators in the windows vertically between the inner-roll blocks carry supports which carry second upper and lower guide elements vertically displaceable on the supports. The positioning actuators are expansible and contractile to displace the second guide elements in the direction. Two working rolls between and parallel to the other roll axes each have two journal blocks fitted to and axially slidable in the second guide elements. An insert carried in the traverses carries rows of bracing rollers which extend axially along the working rolls between same and the traverses. The insert, bracing rollers, and upstream positioning actuators form an integral bracing unit and at least one of the windows is shaped such that the bracing unit can be withdrawn axially through the frame side. Rows of bracing actuators braced in the direction between the rollers and the traverses can press the rollers opposite to the direction against the working rolls.

摘要： The rolling mill for mechanical descaling of hot rolled steel is constructed according to the slidable roll process with reducing rolls so that a unform operation with different and/or changing shape steel strips can obtained. This is attained when the rolling mill has at least two rolls slidable in opposite directions whose body surfaces are constructed with S-shape contours positioned inversely to each other so that these contours compliment each other flawlessly in one certain axial relative position. When sliding the rolls in opposite directions in one case the contour is decreased in the center region of the steel strip and when slid in the opposite directions in the other case the contour is increased in the center region. Thus the rolls can be adjusted to fit a gently convex steel strip profile by axially sliding the rolls in opposite directions as also rolled strips with a thickness centrally reduced in comparison to that of the edge regions can by appropriate sliding of the rolls opposite each other.
摘要翻译： 根据具有还原辊的滑动辊制造热轧钢的机械除锈的轧机，从而可以获得不同的和/或变化的钢带的不一致的操作。 这是在轧机具有至少两个可沿相反方向滑动的辊的情况下实现的，其中主体表面构造成具有彼此相对设置的S形轮廓，使得这些轮廓在一个特定的轴向相对位置中完美地互补。 当在一种情况下沿相反方向滑动辊时，轮廓在钢带的中心区域减小，并且当在另一种情况下沿相反方向滑动时，轮廓在中心区域增加。 因此，可以通过沿相反方向轴向滑动辊来调整辊以适应轻微凸起的钢带轮廓，通过相对于彼此相对的辊的适当滑动，也可以通过相对于边缘区域的中心减小厚度的轧制带。

摘要： An apparatus is provided for removing scale from a hot rolled steel strip by rolls acting by grinding and/or milling so that these rolls are uniformly effective in all regions of the steel strip and an appropriate uniform removal of the scale layer occurs. This is attained when driven grinding rolls adjustable toward the surfaces of the steel strip are provided of which at least two opposing rolls are axially slidable in opposite directions and have inversely oriented S-shape contours. These contours complement each other completely flawlessly in one definite position of the grinding rolls. In one such position the rolls provide a uniform engagement on both sides of a steel strip with a nearly rectangular profile. In fact the rolls by appropriate axial sliding and application of bending forces if necessary may be adjusted to fit the actual profile of the steel strip so that a uniform engagement on the scale layer is guaranteed and a locally excessive grinding and/or milling in the central region of the steel strip is avoided.
摘要翻译： 提供了一种用于通过研磨和/或铣削作用的辊从热轧钢带去除氧化皮的装置，使得这些辊在钢带的所有区域中均匀有效，并且发生适当的均匀除去氧化皮层。 这是通过提供朝向钢带表面可调节的驱动研磨辊来实现的，其中至少两个相对的辊可沿相反方向轴向滑动并且具有反向取向的S形轮廓。 这些轮廓在研磨辊的一个确定位置完全完美地相互补充。 在一个这样的位置中，辊在具有近似矩形轮廓的钢带的两侧上提供均匀的接合。 事实上，如果需要，可以通过适当的轴向滑动和弯曲力的应用来调整辊，以适应钢带的实际轮廓，从而保证在标尺层上的均匀接合，并且在中心部分进行局部过度的研磨和/或研磨 避免了钢带的区域。

摘要： A roll stand has a frame in which upper and lower working rolls are journaled for rotation about respective parallel upper and lower working-roll axes and defining a workpiece nip. Respective upper and lower backup-roll guide elements vertically flank the working rolls and are each at least partially vertically displaceable relative to the frame. Respective upper and lower backup-roll journal blocks are axially displaceable but vertically fixed relative to the guide elements and define parallel upper and lower inner axes flanking the working axes. Respective inner backup rolls are journaled in the blocks for rotation about the inner axes and bear radially toward the nip on the working rolls. The inner backup rolls are therefore axially displaceable in the guide elements. A pair of outer backup rolls are journaled in the frame for rotation about outer axes coplanar with the respective inner axes and bear radially toward the nip on the inner backup rolls. Respective vertically effective actuators for exerting a force at least generally parallel to the planes between each journal block and the frame to bend the inner backup rolls and for displacing the force axially relative to the journal blocks.

摘要： In a four-high rolling mill stand where the work rolls are offset from the perpendicular axial plane of the back-up rolls, they are supported on one side by intermediate rolls and support rollers, and on the other side by hydraulic piston/cylinder units. The work roll bearings are attached to the piston/cylinder units through a sliding guide arrangement, so that they can be slid up and down, from side to side, and the work rolls can also be moved towards and away from the roll gap by actuation of the piston/cylinder units.
