Definitions

  • the invention relates to a device for the contact-free guiding of material webs, in particular metal strips, by means of a gas medium with nozzle boxes arranged above and below and at a distance from the material web, each having a nozzle outlet plane, between which gas extraction channels are provided above and below the material web.
  • Air or inert gas is mainly used as the gas medium, which is blown against the material web.
  • the critical strip thickness can still be less than 0.3 mm.
  • the metal strip of the corresponding thickness or stiffness emerging from the device rather has an impermissibly high proportion of longitudinal folds and other unevenness, so that a high proportion of rejects must be expected.
  • a device is also known (DE-PS 33 18 861) through which webs of material, in particular aluminum strips, can be guided in a floating manner for the purpose of an annealing treatment.
  • nozzle boxes extending transversely to the transport direction of the material webs are used, each of which has two longitudinal slots or rows of holes to form air cushions, the blowing directions of which are inclined towards one another.
  • These shower boxes are arranged in pairs above and below the web. Such a pair of nozzle boxes arranged above the product line is then followed by a further pair of nozzle boxes in the transport direction below the product line. This pair is then connected to a further pair of nozzle boxes in the transport direction above the web.
  • the load capacity of the gas jets emerging from the nozzle boxes and inclined towards one another is very low, so that this device cannot be considered for relatively thick and heavy metal strips.
  • the nozzle boxes in this device must be designed to be quite complex, this known device cannot be used to produce the optimal sinusoidal shape for the carrying and guiding effect.
  • the invention is based on the object of designing a device of the type mentioned at the outset in such a way that it can be used to run both relatively thin and relatively thick and / or rigid strip material, in particular metal strip, in a contact-free manner in a sinusoidal wavy line, for heating or cooling a high power density should be achievable.
  • nozzle outlet planes of the nozzle boxes arranged above and below the web have spacings which differ individually or in groups in relation to a substantially horizontal plane corresponding to the transport direction of the web.
  • the distance between the upper and lower nozzle boxes from the web can be selected according to the load to be carried.
  • the nozzle boxes can have one or more rows of nozzles, it being possible to use slot nozzles and nozzles with a round, oval or other shaped nozzle opening.
  • Air is particularly suitable as the gas medium.
  • the individual nozzle boxes which are arranged above and below the web, are placed in the device in accordance with the desired, possibly sinusoidal, course of the web.
  • the device according to the invention can also be designed so that the nozzle boxes above and below the web are distributed over essentially the same bandwidth.
  • the device according to the invention can also be designed such that the nozzle boxes arranged above the web are offset from the nozzle boxes below the web in the direction of transport. It is possible for a nozzle box on the top of the web to be aligned centrally with two nozzle boxes arranged on the bottom of the web and vice versa. Other offset relations are also possible.
  • the device according to the invention can also be designed such that the nozzle boxes arranged above the web are offset from the nozzle boxes arranged below the web transversely to the direction of transport.
  • the device according to the invention can also be designed such that at least some of the nozzle boxes can be adjusted vertically with respect to a substantially horizontal plane corresponding to the direction of transport. With such an adjustability, the course of the web in the device can be changed. In particular, adaptation to changing material webs and material properties is possible.
  • the device according to the invention can be so forms that at least some of the adjustable nozzle boxes can be adjusted together. In this way, the adjustability of the nozzle boxes with respect to the web can be simplified and thus accelerated.
  • Fig. La shows schematically a device A in the form of a heating furnace or a cooling device.
  • This device A has a fan B, the gas flows in via pressure channels C.
  • Nozzle boxes D promotes.
  • the gas emerges from the nozzle boxes D and hits a web E. From here, the gas is fed back to the fan B via an intake duct F.
  • Heating or cooling elements for the gas streams can be provided in the pressure channels C and / or the intake channel F.
  • a web in the form of a metal strip 1 is passed through the device shown in FIG. 1.
  • Upper nozzle boxes 2 to 5 are arranged above the metal strip 1.
  • Under the metal strip 1 there are opposing lower nozzle boxes 6 to 9.
  • the nozzle boxes 2 to 9 are at different distances from this central plane 10 arranged.
  • the upper nozzle boxes 2 and 4 and the w änteren nozzle boxes are disposed 7 and 9 with the same distance from the center plane 10 degrees.
  • the upper nozzle boxes 3 and 5 and the lower nozzle boxes 6 and 8 are also at the same distance from one another from the imaginary center plane 10.
  • the arrows 11 emerging from each nozzle box 2 to 9 in the direction of the metal strip 1 are intended to exit from the nozzles of each nozzle box 2 to 9 represent emerging gas flows.
  • the upper nozzle boxes 2 to 5 are arranged offset relative to the lower nozzle boxes 6 to 9 in the direction of transport of the metal strip 1 indicated by an arrow 12.
  • the metal strip 1 When the metal strip 1 is subjected to gas flows, e.g. Air or protective gas, the metal strip 1 takes a sinusoidal shape from the nozzle boxes 2 to 9.
  • gas flows e.g. Air or protective gas
  • adjustable throttle valves 14 to 19 are attached, with which the amount of gas to be discharged from the treatment room can be adjusted.
  • adjustable throttle valves 14 to 19 fixed throttle plates or the like can also be used.
  • the upper throttle valves 14 to 16 or the lower throttle valves 17 to 19 can also be dispensed with in whole or in part.
  • the embodiment of the device according to FIG. 2 is particularly suitable for treating particularly stiff or relatively thick metal strip 1.
  • the distance from the upper nozzle boxes 20 to 27 and lower nozzle boxes 28 to 34 to the central plane 10 is changed over the length of the metal strip 1 in smaller increments than in the embodiment according to FIG. 1.
  • the sinusoidal line that the metal strip 1 is correspondingly flat is thus follows when it is transported through the device.
  • throttle devices (not shown) can be present in gas discharge channels 35 between the individual nozzle boxes 20 to 34.
  • the embodiment according to FIG. 3 is also particularly suitable for relatively stiff and thick metal strip 1.
  • the nozzle boxes 36 to 53 are arranged at the same distance from the central plane 10.
  • the nozzle boxes 39 to 41 and 48 to 50 have different, mutually different distances from the central plane 10.
  • throttle devices can be provided in a suitable manner in gas exhaust channels 54 between the nozzle boxes 36 to 53.
  • nozzle boxes 70 to 84 are provided which are not offset as a whole perpendicular to the surface of the metal strip 1 or the central plane 10; rather, only the surfaces of the nozzle boxes 70 to 84 provided with nozzles are arranged in the manner shown perpendicular to the surface of the metal strip 1 and thus offset to the central plane 10.
