Patent number: 11612922Abstract: 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.Type: GrantFiled: April 4, 2019Date of Patent: March 28, 2023Assignee: SMS GROUP GMBHInventors: August Sprock, Christoph Hassel, Ulrich Cramer

Patent number: 11504755Abstract: 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.Type: GrantFiled: January 16, 2020Date of Patent: November 22, 2022Assignee: SMS GROUP GMBHInventors: Thomas Holzhauer, Ulrich Cramer, Andreas Kastner, Magnus Treude

Patent number: 9346090Abstract: 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).Type: GrantFiled: March 14, 2011Date of Patent: May 24, 2016Assignee: SMS Group GmbHInventors: Ulrich Cramer, Thomas Holzhauer, Wolfgang Fuchs, Andreas Kastner, Christian Mengel, Heinz-Adolf Mueller, Carsten Heide, Karl Robert Hofmann

Patent number: 9289809Abstract: 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.Type: GrantFiled: November 8, 2011Date of Patent: March 22, 2016Assignee: SMS GROUP GMBHInventors: Ulrich Cramer, Thomas Holzhauer, Wolfgang Fuchs, Andreas Kastner, Christian Mengel, Heinz-Adolf Mueller, Carsten Heide, Karl Robert Hofmann

Publication number: 20150328670Abstract: 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.Type: ApplicationFiled: July 5, 2013Publication date: November 19, 2015Inventors: Johannes Alken, Uwe Baumgaertel, Ulrich Cramer, Wolfgang Fuchs, Rudolf-Franz Jaeger, Jens Kiessling-Romanus, Matthias Krueger, Frank Theobald

Patent number: 8555476Abstract: 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.Type: GrantFiled: March 14, 2011Date of Patent: October 15, 2013Assignee: SMS Siemag AktiengesellschaftInventors: Ulrich Cramer, Thomas Holzhauer, Wolfgang Fuchs, Andreas Kastner, Christian Mengel, Heinz-Adolf Mueller, Carsten Heide, Karl Robert Hofmann

Publication number: 20130102234Abstract: 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.Type: ApplicationFiled: June 29, 2011Publication date: April 25, 2013Applicant: SMS Siemag AktiengesellschaftInventors: Ulrich Cramer, Thomas Holzhauer
