  • Patent number: 8511126
    Abstract: The invention relates to a cooling device (100) for cooling a metal strip (200) after a forming in a cold rolling stand (200) having at least one nozzle (112) for spraying a cooling medium (400) onto the surface of the metal strip (200). In order to make such known cooling device more effective and efficient, it is proposed according to the invention to provide a plate (500), which in an operating position is arranged parallel to the surface of the metal strip (200) in the run-out of the cold rolling stand (300,) and to arrange the nozzle in the operation position in such a manner that the cooling medium is sprayed at an acute spray angle ? into a cavity between the surface of the metal strip and the opposing plate, with a spray direction (R) opposite to the running direction (L) of the metal strip.

  • Patent number: 8225637
    Abstract: A guiding device for the chocks of work rolls of a rolling stand comprising guides arranged fixedly or horizontally movably on the inner sides of the windows of the rolling stand, wherein the upper and lower bending blocks of each side are respectively assigned two guides arranged parallel to each other. Each bending block is assigned one of the guides, while it has a recess for the parallel running guide that extends around said guide, wherein the upper bending block is guided on one of the parallel guides and the lower bending block is guided on the other guide.

  • Publication number: 20090229935
    Abstract: A housing having a first housing end and a second housing end, a substantially cylindrical work chamber formed in the housing, a piston which is arranged in the work chamber so as to be displaceable and which divides the work chamber into a first work space near the first housing end and a second work space near the second housing end, a piston rod which is arranged at one side of the piston and which projects through the first work space and is guided out of the work chamber in a sealed manner at the first housing end through a guiding and sealing device, and a valve chamber which is formed in the housing parallel to the work chamber and in which a first valve assembly and a second valve assembly are arranged. The work chamber is always completely filled with a liquid medium and the valve chamber is at least partially filled with a liquid medium.

  • Publication number: 20060037989
    Abstract: The present invention pertains to a device for transferring or threading beginnings of a band, especially extremely thin bands, from a band machining or band processing unit to a or into a further processing unit or winding reel, consisting of a transfer table (1), whose width corresponds at least to the width of a band to be conveyed, and whose table surface has a lengthwise slot (8) in the conveying direction of the band, which is narrower than the minimum width of a band to be conveyed, by means of which the upper run of a conveyor belt (7) running in the conveying direction of the band can be pivoted over the surface of the transfer table and to which the band to be conveyed can be connected by external force for a while.
