Abstract (en)
[origin: US6385832B1] 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. The first catch troughs are pivotable independently Of the first water spray nozzles counter to the transport direction about a pivot point and vertically adjustable and automatically yielding relative to the top side. The first spray nozzle rows are arranged in first spray beams, wherein each spray beams has a lever and is freely pivotable about the pivot point of the first catch troughs in order to be vertically adjustable and automatically yielding relative to the top side.
