  • Patent number: 7827891
    Abstract: A shears device including a rolling table, a rail-guided drive carriage coupled with the rolling table, a U-shaped frame mounted on the drive carriage, and a drive apparatus arranged on the drive carriage for driving the shears. The frame has a first side adjacent the drive apparatus and a second side opposite the first side on which holding elements for the shears are provided. At least one of the holding elements on the second side of an upper of the horizontal arms includes a pressure plate. A drive is provided for moving the drive carriage transverse to the transport line. A clamping element is arranged at the second side of the frame and has congruent gliding plates that overlap the pressure plate. The clamping element together with the gliding plates is movable along a horizontal path across the pressure plate to couple the clamping element and the holding element.

  • Patent number: 7293446
    Abstract: The invention relates to a coil box, which is mounted between a roughing rolling train and a finishing rolling train, for metal pre-strips, in particular steel strips, which are hot wound to form coils and are protected against further cooling in the vicinity of a winding and/or unwinding station (6) by means of heat-shield devices (7) on the front faces (5a; 5b) of the coils. The aim of the invention is to universally configure said coil box. To achieve this, the heat-shield devices (7) are configured from lateral walls (8; 8b) that can be pivoted to rest against the front faces (5a; 5b) of the coils and a pair of opposing heat-shield devices (7) can be aligned in parallel to different coil widths (5c).

  • Patent number: 6385832
    Abstract: A descaling device for hydromechanically descaling metal strip has a descaling spray arrangement with first and second spray nozzles arranged adjacent to one another in first and second spray nozzle rows transverse to the transport direction with several first and second spray nozzle rows successively arranged in the transport direction above a top side and underneath a bottom side of the metal strip. The first and second spray nozzles spray a high pressure water jet onto the top and bottom sides. First catch troughs are correlated with the first spray nozzles and catch water of the high pressure water jets of the first spray nozzles. The first spray nozzle rows together with the first catch troughs are pivotable about a pivot axis and vertically adjustable relative to the top side by a signal from a measuring device.
