Definitions

  • the invention relates to a device for descaling Semi-finished products with the features of the preamble of the claim 1.
  • a known device of this type JP-A-52 28 5266
  • the upper part of a nozzle device is by means of a vertical lifting device to compensate for fluctuations in thickness of the semi-finished product to be descaled starting from Signals from a thickness sensor are controlled so that the distance between the nozzle orifices of the upper nozzle device and the surface of the semi-finished product remains constant.
  • This distance is comparative in the known device large. This reduces the jet pressure of the high pressure water on the workpiece. A sufficiently high jet pressure can only by increasing the water pressure or the amount of water can be achieved, which results in a large energy input Has. Reducing the distance of the nozzle device from the belt surface is due to the risk of collision described above not possible.
  • the invention has for its object a device of the type described so that the distance reduced between the belt surface and the nozzle device can be.
  • Claim 1 serves to achieve this object.
  • the nozzle device due to their movable arrangement for movement with a vertical component over the surface of the Semi-finished product of a band unevenness or a bulge at the beginning of the tape in compliance with a preselected small Setpoint distance automatically tracked by the control device.
  • the water pressure in the nozzle or the amount of water can thus be reduced using the invention, resulting in a reduction in cooling in particular leads to thin-walled semi-finished products (thin slabs).
  • the distance can be compared to one Distance of the nozzle device in the range of 250 mm at the known device to 20 to 40 mm, i.e. so up to reduce a tenth. This leads to very significant advantages both in terms of the quality of descaling as also in terms of reducing water and energy consumption and avoiding unnecessary cooling of the semi-finished product.
  • a scale removal device in the same way the bulges or unevenness of the semi-finished product is tracked.
  • the scale removal device in the same way as the Nozzle device with a vertical component movable over the surface of the tape passed underneath be.
  • the invention is based on the drawing with others Details explained in more detail.
  • the only figure shows a schematic side view in the direction transverse to the direction of movement seen a device of the band to be ignited according to the invention.
  • the slab 4 has a bulge 8, which extends over a section or over the total width of the slab 4 can extend.
  • the nozzle device 10 has several, arranged in a row transversely to the direction of movement 6 Nozzle heads 12, each with a total of four Circumference evenly distributed nozzles 14 for spraying High pressure water. There is only one in the drawing to see such a nozzle head 12.
  • the overall arrangement is clearer described in DE 43 28 303 A1. While there, however the nozzle heads on one rigidly above the roller table 2 arranged bars are attached, they are according to the invention attached to a beam 16 by means of a parallel linkage with handlebars 18, 20 vertically in the direction of Arrow 21 can be raised and lowered on a fixed support 23 is held. On the upper link 20 of the parallel linkage attacks a hydraulic cylinder 22 for this purpose.
  • a scale removal device designated as a whole by reference numeral 24 is shown at 24.
  • This scale removal device has a collection housing 26 for from the slab surface rebounded tinder with a baffle 28, of which from the tinder mixed with the high pressure water into one Discharge channel 30 is deflected.
  • the housing 26 is on one vertical bars 32 attached. This bar 32 is over a parallel linkage with links 34, 36 on the carrier 23 hung.
  • the lower link 34 is a hydraulic Cylinder 38 acted upon.
  • the displacement sensor detects the vertical one Distance a between the nozzle device 10 and the Scale removal device 24 and the belt surface.
  • the displacement sensor can be mechanical, optical or be electrically trained and converts the detected distance into an electrical signal via a signal line 42 is fed into a control device 44.
  • This control device is at a desired target distance a at 46 adjustable.
  • the control device 44 compares the measured one Actual distance with the set target distance and provides control signals to reduce the detected deviation ready to zero via signal lines 48, 49 to the cylinders 22, 38 are guided and these for lifting or lowering affect the bars 16 and 32 respectively. In this way the nozzle device 10 and the scale removal device 24 always at a desired distance from the surface the slab 4 is held even if it bulges 8 has.
  • a target distance a is expediently included 20 to 40 mm.
  • the bulges are or bumps 8 often not evenly over the spread the entire bandwidth.
  • multi-part devices consisting of independent sections consisting of bars 16, 24 with parallel linkage and cylinders can be provided.
  • the device according to the invention can by means of a Hoist, such as a crane, designed to be liftable from the roller table 2 be. This allows maintenance and control work and tests away from the roller table, e.g. in a factory, be carried out.
  • a Hoist such as a crane
