Definitions

  • DE 44 22 422 A1 describes a device for contactless sealing of a gap between one Foreclosure and a work roll in the outlet of a Roll stand known with the following features: a) the Partitioning has an end-side partitioning element, which is approximately tangential to the surface of the work roll and at a relatively short distance from it and from the surface the rolling stock is arranged; b) the partitioning element has at least one connected to a compressed air source Supply channel for compressed air, which is in a Direction of the roller axis at a short distance along the The slit nozzle extending on the roll surface opens; c) between the blowing direction of the slit nozzle and one of the Nozzle mouth extending to the axis of rotation of the work roll Normal there is an angle in the direction of rotation of the roller is between 0 and 45 °, preferably 30 °; d) that end-side partition element has on its front almost tangential and at a short distance from Roll surface arranged, tapering like a cutting edge End part,
  • the invention is based on this prior art Task based on a simple and made from rolling mill Specify devices createable device, which in the Is able to deposit moisture on the belt surface in the Avoid reliably running out of cold rolling and strip lines or remove, and with reasonable effort Components and energy can be created and in the area of Outlet of a roll stand can be easily arranged, at Roll change and roll gap setting does not bother you comparatively low noise level.
  • the task is solved at one Device of the type mentioned in the preamble of claim 1 with the invention by the in the characterizing part of claim 1 specified characteristics.
  • An additional one consisting of moving parts Movable partitioning ensures further partitioning of the moist-wet roller area against the finished rolled strip, however allows due to the mobility of the parts advantageous accessibility of the rollers, for example, at Carrying out a roll change. Realize at the same time these moving parts function as a belt deflector and / or a means for band transfer.
  • the as attacks trained moving parts can optionally mechanically fixed or depending on the roll barrel be adjustable.
  • the cover of the band channel is hinged to the Accessibility of the belt e.g. to ease after ligament tears.
  • the figure shows with the omission of the actual roll stand two support rollers (31, 32) and a few between them Work rolls (33, 34). There is a roll gap (12) between them. set.
  • the parts (20, 21) of the movable The partition can be pivoted but also moved linearly be trained. They are with the double link arrangement (24) and a force means (22) so that the with the moving part (20) integrated bale blow-off (3) and the bale gap seal (4) and the band edge blow-off (5) at the same time from the effective position shown in the figure in the area of the work roll (33) can.
  • the power means (22) is preferably a Pneumatic cylinder; but it can also be a hydraulic cylinder or be an electric actuator.
  • the movable part is similar below the belt run (10) (21) with the power means (23) pivotable about the axis (25).
  • the upper cover (15) of the band channel (14) foldable. Due to the flexible design of the elements of the movable bulkhead and the cover (15) of the Band channel (14) is the accessibility in particular Work rolls (33, 34) and the roll gap (12) and the Band (30) easily and in particular without time-consuming Conversion measures guaranteed.
  • the device can preferably be bandwidth-dependent Roll gap lubrication work together, regardless of axially fixed or displaceable or crossed Rollers.
  • the device is designed to prevent it from falling back Moisture in the form of drops or mist the band (30) reliably prevents and thus the band quality optimized.
  • the key to this is in the opposite direction to the tape running direction (13) in Belt channel (14) generated suction flow through the Vapor extraction (6) in cooperation with the Bale gap seal (4) and the bale blow-off (3) in the Roller space (11) above the belt (30).
  • the device forms a functional unit or a system from simple and rolling mill-compatible components and results a dry belt with reasonable energy consumption. To that extent the invention optimally fulfills the above task.
