Definitions

  • the invention relates to a device for descaling Rolled stock, in particular profiles.
  • a descaling device is known from German Patent 1,044,008 known, consisting of a nozzle bar to which a sprayer with a variety of spray nozzles attached is, by means of a control device can be switched on and off in groups. For descaling water is sprayed onto the rolling stock under pressure.
  • spray rings which are equipped with spray nozzles.
  • the spray nozzles individual rings are attached to the cross sections of the profiles adapted and interchangeable depending on the profile to be treated.
  • this requires before changing the rolling program a modification of the scale washer by changing the splash ring or the splash rings.
  • Such a solution is very time consuming and costly.
  • the present invention is therefore based on the object a device for descaling rolling stock, in particular Profiles, to be provided quickly and easily to different Geometries and sizes of the profiles when changing the Rolling program is customizable.
  • the core of the invention is a device consisting of a or more distributor elements rotatable about their longitudinal axis for the descaling agent on which the to be treated Rolled past.
  • At the manifold elements are from each other spaced nozzle assemblies, advantageously rows of nozzles, arranged, where each row of nozzles produces a spray pattern, that is optimal for the cross-section of a profile type or - size is adjusted.
  • the descaling device can be attached to the profile geometry the new conditions by rotating the distributor elements around its axis and locking in the rotational position that the Spray position corresponds to the respective row of nozzles, simple and be adjusted quickly.
  • the distributor element is parallel running bundled tubes, their Have lateral openings that receive the nozzles, the individual pipes with each other independently Descaling agents can be applied.
  • each of the individual tubes with a own coupling device for the supply of the Descaler is provided.
  • This separate coupling device can when editing a different profile cross-section the pipe used in each case to the Supply line can be connected with water or air, which the Handling made easier and quick conversion ensured.
  • the nozzle assembly is preferably a row of nozzles running parallel to the axis of the distributor element, whose length corresponds to the maximum profile width.
  • the adaptation of the nozzles to the different ones Cross-sectional geometries and sizes are preferably carried out by the choice of different lengths of nozzle body and by the Number of nozzles in a row of nozzles. Furthermore, the adjustment about the distance between the nozzles.
  • a descaling device which has two distributor elements, each consisting of several, for example four or five, parallel ones Assemble the pipes.
  • the two tube bundles are arranged above and below the descaling material that the pipe axes are transverse to the direction of flow.
  • Each tube has a row of nozzles, the rows of nozzles of the tubes are offset from one another and parallel to the Pipe axes run. If four pipes are provided, are the rows of nozzles of the tubes are preferably offset by 90 °.
  • Water is generally used as a descaling agent. It is also conceivable to use the descaling process Perform air pressure.
  • Figure 1 shows the cross section of an embodiment of the distributor element 1 (hereinafter referred to as the spray bar) in Form of a tube bundle, which here consists of four arranged in parallel Pipes 2 (shown in dashed lines).
  • the pipes 2 serve to supply the descaling agent, here water, that is applied to the profile 4 under pressure by means of the nozzles 3 becomes.
  • the tubes themselves have a plate 6 at their end edges connected for stabilization. From each of them is parallel to the axis of rotation extending rows of nozzles Cross section only one nozzle visible. There are openings 7 in Pipe jacket provided that receive the individual nozzles.
  • the Nozzles themselves consist of an elongated nozzle body 3 a with outlet opening 3 b. Depending on each they vary in length and profile to be treated their arrangement (not visible). The variation of Angle of attack would be conceivable.
  • FIG 2 shows a descaling device, a so-called Scale washer, consisting of two spray bars 1 a and b, each arranged above and below to profile 4 are.
  • the rolled good for example a rolling block, is transported into the scale washer via roller tables 8.
  • Profile 4 here a double-T beam, passes through the descaling station, consisting of the upper one and lower rotatable spray bars 1 a and b (shown schematically) and two adjustable spraying devices 9 a and b for the outside of the profile flanges 10. Descaling the inside 11, the top and Bottom edges 12, 13 of the flanges and the web surfaces 14 is achieved by the two rotatable spray bars 1 a and b.
  • the upper spray bar 1 a shows that the pipe 21 a in use has a Coupling device 15 with a water supply line 16 connected is. If the rolling program is changed, the Water supply temporarily interrupted and the water supply of the spray tube 21 a which had been in use until then uncoupled. The spray bar is in a new working rotary position brought and locked. That is now used Coming spray pipe is over its own coupling device connected to the water supply and with water acted upon. This conversion process is simple and can be carried out quickly and only takes a few minutes.
  • the lower spray bar 1 b illustrates the four different ones Row of nozzles, each in this embodiment are at right angles to each other. It can be seen that the individual nozzles due to different length of the nozzle body as well as the number of nozzles to the respective profile geometry are adjusted. Furthermore, the nozzles can be in different Be spaced from each other (tube 23).
  • the measures according to the invention are not based on the exemplary embodiment limited. They are distribution elements with less or more than four pipes conceivable. Preferably, the Distributor elements arranged transversely to the direction of flow, they can also take other angles.
