Definitions

  • Figure 1 shows an end sealing element (2) in Figure 2 completely shown device.
  • the Partitioning element (2) or its end part (3) is under Formation of a contact-free gap approximately tangential to the surface of the work roll (20) and in a relatively small amount Distance to this as well as to the surface (31) of the rolling stock (30) arranged. It has at least one on a compressed air source (10) connected supply duct (11) for compressed air, which in a little in the direction of the roller axis Gap nozzle extending at a distance along the roll surface (12) flows into. This emerges with pressures between 0.5 and 4 bar of compressed air supplied to form a energy-rich and covering the width of the roller (20) Air jet.
  • FIG. 1 A favorable form of flow of the driving jet for training a negative pressure in the flow channel (25) is shown in FIG. 1 achieved in that the gap nozzle between a gradation (14) of the end part (3) and a the width of the nozzle gap (17) determining adjustable guide member (15) is.
  • the gap of the nozzle (12) is between 0.1 mm in widths and 4 mm adjustable, the preferred width is 0.2 mm. This will continue to expand the jet favors that the guide member (15), seen in cross section, starting from the direction of the nozzle gap (17) in a backward curved flow guide surface (16) merges. Thereby there is a bumpless, constant spreading of the Jet jet for a powerful suction.
  • the gap of the gap nozzle can be located in the area of the roller (20) (12) can be relatively larger, which means larger amounts of air here be sucked off.
  • each intake duct (4) obliquely upwards in the acute angle (beta) directed against the roller surface is.
  • Fig. 1 it is also shown that the partitioning element (2) at least one at a distance behind the gap nozzle (12) Has water drainage channel (26). This will cause airflow entrained liquid, which is in the form of drops on the Partition element (2) precipitates, derived to the side and thus prevents liquid from running back.
  • Figure 2 shows the arrangement according to the invention in the installed state inside the bulkhead (1).
  • This arrangement results in a very effective combination of blow-off of the roller (20) and Suction of the surface (31) of the rolling stock (30) comparatively small space.
  • the partitioning element (2) is arranged, the gap nozzle between this and its end part (3) (12) is formed.
  • the end part (3) is touchless a small gap-like distance approximately tangential the surface of the roller (20).
  • the gap nozzle (12) is with connected to the supply duct (11) for compressed air.
  • Trough (40) arranged with side drain pipes (41).
  • the trough (40) serves to collect Liquid droplets resulting from the wet flow of the Depress flow channel (25 Fig. 1). Furthermore shows Fig. 2 shows the arrangement of blowing nozzles (45) on a nozzle head (44). These have the task of the edges of the rolled strip (30) of entrained liquid such as water and / or rolling oil to blow off.
  • the air space (47) between the rollers (20, 21) and the bulkhead (1) is connected to an extractor fan (48) connected.
  • the device is straightforward due to the fluidic design very effective and fulfilled in optimally the task at the beginning.
