Definitions

  • the invention relates to a device for guiding a metal strip on a gas cushion with blow boxes arranged one behind the other in the strip longitudinal direction, the nozzle fields of which extend transversely to the strip longitudinal direction and have perforated nozzles distributed over the field surface and slot nozzles along the edges running transverse to the strip longitudinal direction.
  • slot nozzles parallel to the edge prevent the gas from flowing out of the perforated nozzle area in the longitudinal direction of the strip, the discharge of the gas from the air cushion transversely to the longitudinal direction of the strip cannot be prevented by such slot nozzles.
  • the invention is therefore based on the object to design a device for guiding a metal strip on a gas cushion of the type described in such a way that with a uniform distribution of the perforated nozzles across the width of the strip to be treated, an increase in load capacity is possible without increasing the gas volume flow to have to.
  • the invention solves the stated problem in that the slot nozzles along the edges consist of several nozzle slots arranged one behind the other in a row parallel to the edge, which are inclined inwards from the respective center of the edge relative to the edge.
  • the inward inclined longitudinal slots along the edges of the nozzle fields running transversely to the longitudinal direction of the band thus bring about an advantageous increase in the load-bearing capacity through the interaction of, on the one hand, the obstruction of the gas flow transversely to the longitudinal direction of the band and, on the other hand, the support of an additional outflow of gas in the longitudinal direction of the band, without sacrificing even heat transfer between them the gas flow and the metal band.
  • the choice of these parameters allows the nozzle field to be adapted to different conditions.
  • the nozzle slots starting from the respective edge center of the nozzle field edges can run parallel to one another.
  • the inclination of the nozzle slots can increase with increasing distance from the respective lige edge center increase to have increasing influence against the longitudinal edges of the metal band on the outflow behavior of the gas cushion transverse to the longitudinal direction of the band.
  • nozzle slots according to the invention in the edge region of a nozzle field in a plan view in a larger scale
  • Fig. 3 is a representation of a construction variant of the nozzle slots corresponding to FIG. 2.
  • the device for guiding a metal strip 1 consists of a frame 2 carrying 3 blow boxes 4 arranged in series in the longitudinal direction of the strip, which form nozzle fields 5. These nozzle fields 5 extend transversely to the belt longitudinal direction 3 and have perforated nozzles 6 distributed over the field surface, through which Gas, for example air, is blown against the metal strip 1 to form a gas cushion. Slit nozzles 8, which consist of individual nozzle slits 9, are provided along the edges 7 of the nozzle fields 5, which run transversely to the strip longitudinal direction 3.
  • nozzle slots 9, arranged one behind the other in a row parallel to the edge, are - starting from the respective edge center 10 - inclined inwards with respect to the edge 7, so that the nozzle slots 9 opposite one another with respect to the nozzle array 5 narrow the nozzle array against the longitudinal edges 11 of the metal strip 1.
  • the constriction of the gas cushion generated via the perforated nozzles 6 causes a hindrance to the outflow of the gas transversely to the longitudinal direction 3 of the strip, which results in a corresponding increase in the static pressure of the gas cushion and thus in an increase in the load-bearing capacity.
  • the gas backflows 12 get into backflow channels 13, which extend from the longitudinal center of the metal strip 1 against the longitudinal edges 11 with respect to the flow cross-section through roof-like sloping wall surfaces 14 to the To keep the return flow speed in these return flow channels 14 comparatively small.
  • the longitudinal slots 9 of the slot nozzles 8 run parallel to each other, so that the angle of inclination ⁇ of these nozzle slots are the same.
  • the nozzle slots 9 must not overlap. They therefore end in the area of a common straight line 15 running in the longitudinal direction of the strip, so that the nozzle slots 9 directly adjoin one another transversely to the longitudinal direction of the strip, but offset from one another in the longitudinal direction 3 of the strip.
  • the nozzle slots 9 according to FIG. 3 are not aligned parallel to one another. Rather, the inclination of the nozzle slots 9 increases with increasing distance from the center 10, so that the angle of inclination ⁇ increases from the nozzle slot to the nozzle slot 9 starting from the center 10.
  • This increase in the angle of inclination ⁇ causes an increasing constriction of the air cushion produced by the perforated nozzles 6 against the longitudinal edges 11 of the metal strip 1, with the advantage that the free outflow of the gas from the air cushion transversely to the strip longitudinal direction 3 is increasingly impeded. This means that the static pressure in the area of the air cushion and thus the load capacity of the air cushion can be increased.
