  • Patent number: 11440066
    Abstract: A first steel strip and a second steel strip (7) are rolled in succession in at least one roll stand (1) of a cold rolling mill. A rolling pause, in which no steel strip is rolled, is provided between the rolling of the first and the second steel strip (7). The first steel strip is fed over a first path starting from a first pay-off reel (2), and the second steel strip (7) is fed over a second path starting from the first pay-off reel (2), or from a second pay-off reel different from the first pay-off reel (2). The first steel strip is not heated as it is fed to the rolling mill (1), whereas, by contrast, the second steel strip (7) is heated. The second path is longer than the first path.

  • Publication number: 20200047231
    Abstract: A descaling device (2) for chemically descaling a metal strip (4): A spraying device (12, 12a-12d) for spraying a pickling agent (14) onto a top or bottom side (16, 18) of the metal strip (4). The spraying device (12, 12a-12d) has a first outer spraying unit (50) for spraying the pickling agent (14) onto a first edge region (52) of the top/bottom side (16, 18) of the metal strip (4) and a second outer spraying unit (54) for spraying the pickling agent (14) onto a second edge region (56) of the top/bottom side (16, 18) of the metal strip (4), which second edge region lies opposite the first edge region (52). At least one of the two outer spraying units (50, 54) has one or more solid stream nozzles (20), in particular a plurality of rows of solid stream nozzles (20), and/or one or more slotted nozzles (22).

  • Patent number: 9534302
    Abstract: A device and method for post-treating a metal strip, wherein a pickled metal strip (2) coming from a pickling zone is advanced continuously through a rinsing zone (4) in which residues of a pickling agent adhering to the surface (11) of the metal strip (2) are removed by spraying the metal strip with rinsing fluid. At least one device (8) for generating a liquid mist (9) is provided in the rinsing zone (4). The device (8) can moisten the surface (14) of the metal strip (2) during an interruption of the continuous operation or of a sharply reduced speed of the strip. The device (8) has mist spraying jets above the surfaces of the metal strip.

  • Patent number: 5238199
    Abstract: An arrangement for laying a wire in circular windings by bending the wire to circular form during simultaneous twisting includes a wire conveying device and a consecutively arranged laying head including a rotating laying pipe, whose central axis is oriented tangentially to the wire axis on the wire entry end and which gradually passes from the entry end into a circular arc directed approximately perpendicular to the axis of rotation, its center lying on the axis of rotation. A twisting device is provided between the wire conveying means and the laying head. In order to be able to lay wires of larger diameters in closely adjacent windings, the twisting device is formed by a bent pipe twisting the wire under positive locking and frictional engagement.
