Definitions
- the invention relates to a device for guiding a metal strip on a gas cushion with blow boxes lined up in the longitudinal direction of the strip at a distance, which have nozzle fields extending transversely to the longitudinal direction of the strip with perforated nozzles distributed over the field surface.
- the gas cushion is not only used for contactless guidance of the metal strip, but also for heat transfer, heat treatment of the metal strip must also take into account the heat influences which, among other things, require the metal strip to bulge around a central longitudinal axis. This means that the distance of the metal strip from the nozzle field is greater in the central region than in the region of the longitudinal edges of the metal strip. Because of this band curvature, the conditions for the supporting air cushion must be selected so that a sufficient distance from the blow boxes can be ensured in the central region of the metal band in order to be able to exclude contact in the longitudinal edge region.
- the invention is therefore an object of the invention to provide a device for guiding a metal strip on an air cushion of the type described in such a way that a metal strip that bulges under the action of heat can be guided without contact, without a loss of load-bearing capacity due to the curvature of the metal strip to have to take.
- the invention solves the stated problem in that the nozzle fields have a convex basic shape by at least in one end section falling to both sides transversely to the strip longitudinal field sections.
- convex basic shape of the nozzle fields By an adapted to the curvature of the metal strip, convex basic shape of the nozzle fields, an approximately uniform distance between the metal strip and the nozzle fields can be ensured in a simple manner, so that the load-bearing capacity of the air cushions generated by the nozzle fields can be fully utilized without danger to run so that the longitudinal edges of the tape touch the blow boxes.
- the convex basic shape of the nozzle fields which is matched to the curvature of the heated metal strip, also ensures that the metal strips are subjected to a largely vertical flow, even in the longitudinal edge area, so that overall advantageous bearing conditions can be guaranteed.
- the continuous curvature of the metal strip transversely to the strip longitudinal direction can be realized by field sections in an end section of the nozzle arrays which drop transversely to the strip longitudinal direction.
- the field sections of the nozzle fields can increasingly decrease on both sides. This condition can be achieved by polygonal longitudinal sections of the nozzle fields.
- a constant curvature of the nozzle fields is also possible, but this is associated with a correspondingly greater production outlay.
- blow boxes with corresponding nozzle fields are provided both below and above the metal strip to be guided without contact, in order to enable uniform heat treatment from both sides of the metal strip.
- the upper nozzle array With such a nozzle array arrangement below and above the metal strip to be guided, it is advisable to design the upper nozzle array with a concave basic shape adapted to the convex basic shape of the lower nozzle array.
- This concave basic shape of the upper nozzle fields naturally does not affect the load-bearing capacity, but has a significant influence on the uniform heat transfer, which need not be explained in more detail.
- the device for guiding a metal strip 1 consists of a frame 2 which carries blow boxes 4 which are arranged one behind the other in the strip longitudinal direction 3 and which form nozzle fields 5.
- These nozzle fields 5 extend transversely to the strip 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 are provided along the edges 7 of the nozzle fields 5 which run transversely to the longitudinal direction 3 of the band and which limit the field of the perforated nozzles 6 and support the gas cushion built up by the perforated nozzles 6 with their gas jets.
- the gas flow deflected on the metal strip 1 flows on the one hand between the two rows of slotted nozzles of each nozzle field 5 against the longitudinal edges 9 of the metal strip 1 and on the other hand reaches the return flow channels 10 formed between the blow boxes 4, which flow from the longitudinal center of the metal strip 1 against the longitudinal edges 9 expand due to roof-shaped sloping frame surfaces 11 with regard to the flow cross-section in order to low flow velocity and thus a comparatively low pressure drop.
- the nozzle arrays 5 In contrast to conventional nozzle arrays, the nozzle arrays 5 according to the invention have a convex basic shape which is adapted to the curvature of the heated metal strip 1 in order to ensure an approximately constant distance between the metal strip 1 and the nozzle surfaces 5.
- the convex basic shape of the blow boxes 4 is achieved by starting from a central section 12, increasingly sloping longitudinal sections 13 of the field surface, which are strung together like a polygon, in order to adequately adapt to the continuous curvature of the curved metal strip 1 with simple construction To enable funds. Because of this adaptation, advantageous load conditions are established without endangering the contactless guidance of the metal strip 1 on the gas cushion of the nozzle fields 5.
- the blow boxes 14 arranged above the metal strip 1, indicated by dash-dotted lines, can also be adapted to the curvature of the metal strip 1 Nozzle fields 5 are provided, which then have a correspondingly concave basic shape, so that in turn the distance to the metal strip 1 can be kept approximately the same over the bandwidth.
- the invention is of course not limited to the illustrated embodiment, because it is, for example, not about the type and arrangement of the nozzles, but ied just about the convex, adapted to the curvature of the heated metal strip 1 basic shape of the lower blow boxes 4 and possibly the concave basic shape the nozzle fields 5 of the upper blow boxes 14 are, on the one hand, advantageous carrying conditions
