  • Patent number: 11612922
    Abstract: A cooling device for cooling a metallic item and a method for operating the cooling device. Such cooling devices having a plurality of cooling bars arranged in parallel in groups for applying a coolant to the metallic item are known in the prior art. In order to be able to set a desired distribution function of the coolant over the width of the metallic item as precisely as possible, the cooling device provides that similar application regions in at least two cooling bars within a group are each formed differently with respect to their contour and/or with respect to their surface area.

  • Patent number: 11504755
    Abstract: A device for producing strip material, such as a hot strip. The device includes lateral guide elements which are arranged on both sides of the strip material and, in particular, along a roller table having several rollers, and at least one rotating wear body on each side guide element. In order to minimize the wear of guide elements when transporting the strip material over a roller conveyor, a speed control device regulates a rate of speed of the at least one wear element. Further, a position control device is provided for setting an extended position of the at least one wear element. The position control device sends control signals to a positioning drive for extending the at least one wear body to an extended position.

  • Patent number: 10906078
    Abstract: An apparatus for winding up a metal strip into a coil. A frame in which a second counter-bending roller is mounted in a rotatable manner. The frame is movable with the aid of a second setting device between a coiler shaft position and a roller bed position. In the roller bed position, the second counter-bending roller alongside a first counter-bending roller acts as the roller bed roller of a roller bed which is arranged above the coiling device.

  • Patent number: 9346090
    Abstract: The invention relates to a method and a device for depositing a metal coil (200) on two stationary support points (110-1; 110-2). In order to be able to deposit even metal coils that have high internal residual stress in a stable manner on the two support points, according to the invention, a third support point (140) is pivoted against the outer circumference of the metal coil (200) if needed).

  • Patent number: 9289809
    Abstract: The invention relates to a device and a method for handling a metal strip. The device comprises a coiling device (110) with a coiling mandrel (112) for winding the metal strip to form a coil (200) on the coiling mandrel and a coil stripper car (120) with supports (124) for receiving the coil (200) from the coiling mandrel and removing the coil from the coiling device (110). In order to additionally secure the metal strip in the coiling device during the transfer from the coiling mandrel onto the coil stripper care and during a transport by means of the coil stripper car, a first hold-down arm (130) is provided for exerting a first hold-down force (F1) onto the outer circumference of the coil (200) in order to press the coil onto the supports of the coil stripper car.

  • Publication number: 20150328670
    Abstract: The present invention relates to a method of dynamically supplying coolant to a cooling device, in particular at least one spray bar, for cooling metal strip or other rolled stock. According to the method, a pre-accelerated stream of coolant is provided, which passes by the cooling device (1) and is fed into a return (3). Furthermore, the presence and/or the temperature of a metal strip or other rolled stock to be cooled is monitored and, dependent on the presence and/or the temperature of the metal strip or the other rolled stock, the stream of coolant is diverted to the cooling device (1), wherein, instead of passing by the cooling device (1) and being fed into a return (3), the stream of coolant is fed to the cooling device (1) for cooling the metal strip or the other rolled stock. The present invention also comprises a corresponding device for carrying out the method.

  • Patent number: 8555476
    Abstract: The invention relates to a device and a method for depositing a metal coil (200) on two support points (110-1; 110-2). In order to avoid risks, in particular instability, while depositing metal coils having high residual stress, according to the invention the risk of an unstable position of equilibrium is checked, if a change in the relative position of the two support points (110-1; 110-2) with respect to one another is foreseeable, it is carried out such that the metal coil (200) comes to rest on both support points at least approximately in a stable position of equilibrium.

  • Publication number: 20130102234
    Abstract: The invention describes a polishing device (100) for polishing a component (200), comprising an elongated polishing element (110), which is directed against the surface (205) of the component (200) parallel to the longitudinal axis (z) of the component (200). In this case, the polishing element (110) is formed in adjustment subsegments (110-1, 110-2, . . . 110-n) in its longitudinal extent. A housing (120) serves for receiving the polishing element (110). Arranged between a bearing surface (123 of the housing (120) and the polishing element (110) is a pressure-exerting element (130), for placing and pressing the polishing element (110) against the component (200). In this case, the pressure-exerting element (130) is formed as at least one flexible tube to which pressure can be applied.

  • Patent number: 7328598
    Abstract: The invention relates to a device for cooling rolling stock within the cooling stretch of a rolling mil, especially a hat-strip mill, whereby water spray devices are stationarily mounted below the rolling stock between rollers (10) of a roller train (1) and spray bars (3) held on support levers (16) are arranged above the rolling stock. The support levers are held be a tubular, rotationally driven and water-fed articulated tube (15) that extends in parallel to the longitudinal axis of the roller train. The device is further provided with a central water feed tube and an automatic control device with associated on/off valves for switching the cooling water on and off. The aim of the invention is to improve a device of the aforementioned kind in such a manner that the maximum cooling capacity to be obtained is increased while the length of the roller train required therefor is reduced, thereby attaining a compact design and high cooling capacity.
