Definitions

  • the invention relates to a belt treatment line and a method for treating Metal bands, in particular for high-strength stainless steel bands, according to the preamble of claims 1 and 14.
  • Treatment lines For example, they pass through cold-rolled stainless steel strips a cleaning station before entering an annealing furnace arrive and be sent for further processing.
  • the cleaning station will be large quantities of Cleaning fluid applied to the tape to put on it Adhesive residues, such as loose tinder, tinsel, oil residues and Another thing to remove, which in the previous ones Made manufacturing steps or remained on the tape are.
  • the invention relates to a method for Treating metal bands.
  • a fundamental problem in the treatment of Metal bands is that the band in many cases depending on the design and function of each Treatment stations over a longer path without the Possibility of support must be performed. This can for example, in annealing furnaces, in sling towers or similar facilities will be required.
  • the advantage of the known device is that itself by a suitable positioning of the straightening roller in Regarding the guide rollers assigned to the size and the kind of for the correction of flatness errors of the Bandes required deformation in a simple manner to let. Because the deformation as a pure bending shape change is done for judging itself no additional tensile forces needed, so that the strip tension only for the transport of the tape through the Device must be measured.
  • a treatment line for metal strips known that equipped with a treatment section is that comprises a first treatment station in which a liquid the processed metal band wetted.
  • the tape then goes through one Deforming device, wherein there is still a temperature of preferably 600 ° C to 800 ° C has.
  • the Deformation device will compensate both Deformations of the band as well as an elongation of the band performed.
  • Disadvantage of disclosed in US 4,074,555 Device is that due to the high temperatures of the Tape the water on the tape while running into the Deformation device is completely evaporated, so that a direct contact between, for example, roles of Deforming device and the tape is done. This will The aim of breaking up the scale in the prior art promoted. At the same time, however, the above can already mentioned undesirable markings of the strip surface arise.
  • the object of the invention is a Band treatment line and a method of the type described above in which the risk of damaging the Surface of the processed metal strip further reduced is.
  • this object is achieved in a generic belt treatment line achieved in that the treatment station so is set up that they each of them Metal strip essentially completely with liquid like that wets that the metal band is still in liquid wetted state passes through the deformation device, which the metal strip by substantially pure Bending shape change directed.
  • the above said object by a method for treating Metal bands, in particular of high strength Stainless steel bands solved, in which each processed Metal band goes through a band treatment section, in it in a first treatment station with liquid is wetted and passes through a deformation device (12) in a second treatment section.
  • the deforming device in which it while maintaining a liquid film between the Straightening elements of the deformation device by in essentially pure bending shape change is directed.
  • the tape while still wet with liquid is guided by the deformation device is achieved that also between the straightening elements of Deforming device, such as straightening and / or Guide rollers, and the respective metal band always Liquid film is present.
  • This liquid film prevents adhering to the tape residues on the get relevant elements of the deformation device, stick there and then damage the Cause ribbon surface.
  • the invention thus uses the Presence of liquid in the wet part of the Treatment line out to damage the Belt surface when straightening in the deformation device to prevent. So not only is the hassle for that Bending density as such is reduced to a minimum, but it is also no additional effort for the application or removing lubricants or similar Liquids in the area of the deformation device required.
  • the deformation device may be, for example to act as a device for bending, as in EP 0 865 839 A2 is described.
  • Essential is that the deformation of the metal strip to the far is predominantly executed as a bending shape change, in the tensile forces essentially exclusively for Transport of the tape will be needed, and that the processed tape is wetted with a liquid.
  • the advantage of saving energy and equipment Effort for the drives, this ensures that the tape no excessive load during straightening itself which is subjected to undesirable deformations could lead.
  • the deforming device within the treatment station is arranged.
  • a liquid film that is so strong that between the band and the straightening elements of the Deformation device liquid like a "Aquaplaning effect" accumulates and so a direct Contact between band and straightening elements effective prevented. It is useful in this context, if the deforming device near the exit of the Treatment station is arranged, since in this area the Amount of impurities adhering to the belt, such as Baubles, tinder remains etc., are largely removed.
  • the deformation device in Direction of conveyance of the metal strip in direct connection to arrange at the treatment station. It is essential only that a sufficient liquid film on the Metal strip is present when it is in the Deformation occurs.
  • Another way of training the Deforming means is that the Deforming device two of the metal strip in succession has partially-wrapped straightening rollers. Also by the Use of two straightening rolls, which from the metal strip in immediately after each other the metal strips bend without additional Tensile forces must be introduced. Thereby the way of the Metal bands in the area of the deformation device expediently an S-shaped course. this makes possible to use the straightening rollers particularly effectively.
  • a further advantageous embodiment of the invention is that the deformation device is a Control device comprises, which in the Deformation device performed bending in Dependence on the result of one on the metal strip controls the tape curvature measurement.
  • the strip processing line 1 comprises an unwinding device 2 for unwinding a wound to a coil 3 cold-rolled stainless steel strip B.
  • the coiled Stainless steel strip B passes through in the conveying direction F first a cleaning device 4. Then it is in a distance from the cleaning device. 4 arranged continuous annealing furnace 5 annealed.
  • a Coiler 6 positioned on the annealed Stainless steel band B is rewound to a coil 7.
  • the stainless steel strip B enters through an inlet opening 8 in extending over a certain length L extending Cleaning device 4 a.
  • the cleaning device 4 are in successive in the conveying direction F Row nozzles 9 arranged over which Cleaning fluid under increased pressure on the upper and bottom of the stainless steel band B is applied to on the stainless steel band B adhering contaminants, such as Tinsel, oil residue and the like, to remove.
  • the Stainless steel strip B leaves the cleaning device 4 by an exit port 10 after the cleaning fluid by means of a closely adjacent to the outlet opening 10th positioned scraper 11 of his Surfaces has been removed.
  • the stainless steel band B is in one within the Cleaning device 4 arranged deformation device 12 bent.
  • the deformation device 12 has a from the stainless steel band B partially-strapped straightening roller 13 and two guide rollers 14,15 on.
  • the guide rollers 14,15 have a larger diameter than the straightening roller 13. They are arranged axially parallel so closely adjacent, that between them a gusset area 16 is formed, in which the straightening roller 13 is positioned.
  • the position of the straightening roller 13 and the guide rollers 14,15 be adjusted relative to each other.
  • the Fulcrum 19 of the straightening roller 13 additionally in a plane 20th adjustable, perpendicular to the stainless steel band B level is adjustable.
  • the degree of Looping the straightening roller 13 through the stainless steel band B be set. This setting is done in Dependence on the result of a by a measuring device 21 performed measurement of the flatness of the stainless steel strip B when leaving the cleaning device 4.
  • the Stainless steel band B by a pure bending shape change directed.
  • the arrangement and geometric relationships of Straightening and guide rollers 13,14,15 are doing so chosen that acting on the stainless steel band B strip tension makes no contribution to this change in form. He serves only to transport the stainless steel band B through the Band treatment line 1. In this way it is avoided that the stainless steel band B when passing through the Deformation 12 undergoes an extension.
  • the cleaning liquid R with which the stainless steel band B is wetted in the cleaning device 4, accumulates in the area of the contact lines 17, 18 in the manner of a "Aquaplaning effect" on. That's that way between the guide rollers 14,15 and the top of the Brassbandes B or between the straightening roller 13 and the Bottom of stainless steel band B adjusting Liquid film causes on the stainless steel belt B still existing loose contaminants on the peripheral surfaces of Straightening and guide rollers 13,14,15 arrive and there be rolled. That way, it will be effective prevents it in the region of the deformation device 12th to damage the surfaces of the stainless steel strip B comes.
