  • Patent number: 7398666
    Abstract: The invention relates to a method of rolling a strip-shaped in-process stock, in particular a metal strip, with which, a metal strip (3) is unwound from a coil (2, 7) held on an unwinding reel (1, 6), is fed into a reversing rolling mill (8), is rolled, and is wound-up onto a winding-up reel (9) to form a coil (10), wherein the metal strip (3) is reversibly conveyed from the unwinding reel (1, 6) to the winding-up reel (9) until a set thickness is reached and, with each passing of the reversing rolling mill (8), is subjected to a reduction of thickness, and wherein an end of the metal strip (3) of a first coil is welded to a beginning of the metal strip (3) of the second coil, and the metal strip (3) of the first coil is temporarily stored in a strip store during a welding process, and finally, the in-process stock consisting of two lengths is reversibly rolled to a final dimension, and an additional length is welded to the end of the in-process stock before the last pass.

  • Publication number: 20080125298
    Abstract: The invention relates to a method for manufacturing a metal strip (1), in which the metal strip (1) is guided over a number of rolls (2, 3, 4, 5) under such a strip stress (S), and is moved in a conveying direction (F), that it is largely flat at least between two rolls (2, 3). In order for it to be possible to inspect the strip in a simple and space-saving way, the invention provides for the inner tensile stresses which act in the metal strip (1) which is largely flat under tensile stress between the at least two rolls (2, 3), to be made optically visible and for the tensile stresses or tensile stress differences which are determined in this way to be utilized during the manufacture of the metal strip (1). Furthermore, the invention relates to an apparatus for manufacturing a metal strip.

  • Patent number: 7347073
    Abstract: A rolling mill frame for the rolling of different rolled stock which requires different rolling forces and which has working rolls, back-up rolls, optionally a roll being device for the working rolls and optionally a device for adjusting and balancing the back-up rolls. The mill has pairs of adjusting cylinders between the roll stand and the chocks of the rolls which avoid large friction losses. The adjusting cylinders are each comprised of a telescoping cylinder in which a first cylinder with a large diameter for high rolling forces and a concentric cylinder with smaller diameter for smaller rolling forces are provided.

  • Patent number: 6834521
    Abstract: In a method for drying and keeping dry rolled strip in a delivery area of strip-rolling plants, a partition is arranged in the delivery area for separating a damp area of the rolling mill from a dry area. The partition extends from the base plate to the stand platform. The strip is subjected to pressurized gas by the ends of the partition facing the strip at a right angle to the strip surface from above and below. Across the strip width a cushion of a compressed gas is generated and seals a gap between the ends of the partition facing the strip and the upper and lower strip surfaces. The compressed gas is guided away above and below the strip parallel to the strip surface as a split flow toward the rolling mill or the damp area and as a split flow in the opposite direction toward the dry area.

  • Publication number: 20030146335
    Abstract: The invention relates to a device for receiving, transporting onwards and unwinding coils of rolled strip (WB) which are successively transported to the device from a strip rolling mill or a rolled strip storage unit. The device consists of a carousel-type support (KT) which can be driven in rotation about a vertical axis (VA) and on which a pair of radially projecting, rotationally mounted support mandrels (TD) with axial locking elements are located, these support mandrels being angularly offset from each other about 190°. The carousel support (KT) pivots the support mandrels out of a receiving position (A) for the coils of rolled strip (WB), into an unwinding position (C), about a pivot angle of 180°. The carousel support also has at least two other support mandrels (TD II and TD IV) which are offset from the two aforementioned support mandrels (TD I and TD III) by 90°, respectively.

  • Patent number: 6138487
    Abstract: A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.
