Definitions

  • the invention relates to a device for floating guidance and stabilization of strips, preferably metal strips, for the purpose of heat treatment of the genus specified in the preamble of claim 1.
  • the tapes are blown with treatment gas suspended from below and possibly also from above while doing so heat treated at the same time.
  • the heat treatment can heat and hold to annealing temperature and subsequent cooling for metallurgical reasons or also for the purpose of surface treatment, e.g. B. drying one Coating the tape.
  • Such devices are usually made of individual, one behind the other Sections constructed and included, such as DE-OS 2446983 or DE 4010280 A1 shows, for each section, a flow guide with at least one fan and across Floating nozzle systems arranged above and below the belt for the belt run, with which the tape is used for the purpose of convective heat exchange blow the gas circulated by the fan and at the same time through the acting Flow forces is stabilized.
  • the device according to DE-OS 2446983 is arranged laterally by only one Fan per section achieved a particularly compact design, but there one fan that supplies both upper and lower floating nozzles is one easy adjustment of the load capacity, e.g. B. to adapt to the weight of the floating to leading band, not by changing the fan speed possible because it affects the upper and lower nozzle systems in the same way would.
  • the device according to DE-OS 2446983 has the disadvantage that the backflow of the treatment gas inflated onto the belt only after one side towards the fan. This creates a backflow from the belt and inflow in the nozzle fins for a heat exchange in the Cross current, which z. B. in a heating zone in which the gas from the belt flows out colder than it is inflated onto the belt, a decrease in temperature of the inflated gas along the rib of the nozzle facing away from the fan Side to the fan side.
  • the device according to DE 40120280 A1 avoids this disadvantage by mutual inflow to the nozzle fins within a section, required but four fans per section and is therefore only for systems for floating Run very wide tapes where appropriate because of the larger ones to be blown Area and the higher gas volume flow required thereby this higher technical effort is worthwhile.
  • a big disadvantage of this device with side supplied nozzle fins is that complex guide vane systems for recirculation the nozzle outflow must be used perpendicular to the belt surface, which cause noticeable pressure drops in addition to costs.
  • the invention is therefore based on the object, a device of the specified To create genus that avoids the disadvantages described.
  • a technically relatively inexpensive, compact device is to be provided in which the bilateral adjustment of the flow to the weight of a Band or the regulation of the load capacity in a simple manner by changing the Fan speed is possible.

  • nozzle openings are partially grouped around outflow openings. These outflow openings are formed by the inlet cross section in channels, which the flow channel penetrate perpendicular to the band plane.
  • the Backflow from the belt to the fan partly through these flow channels, where the division of the backflow into the portion that is lateral to the belt flows back, and takes place in the proportion, which by the above, the Flow channel penetrating backflow channels the load capacity characteristic of Floating nozzle field determined.
  • the major part of the outflow takes place on both sides the device and comes out of the room to the side of the flow channel in the area between the two U-legs, towards which the suction opening the centrifugal fan is oriented.
  • heating devices are at least a side wall of the outer case built in and protrude into the space between the Legs into the U-shaped flow guide.
  • the electrical heating register is either in the range of Deflection of the U-shaped flow guide installed or on the suction side in front of the Fan arranged.
  • the cooler for the circulating gas in the area of the U-shaped deflection installed the cross section of the to increase the installation area Flow guidance - viewed from the fan - to the cooler inlet cross-section can expand. It is also the arrangement of the cooler on the suction side in front of the Fan possible.
  • the floating nozzles can via the flow guide channel from which they are supplied will survive laterally.
  • the device shown in Figure 1 is used for floating guidance and stabilization from narrow to medium-wide metal bands. This means metal straps with a width between about 800 mm and 1200 mm.
  • This device has, see Figure 1, four heating zones 2 and two cooling zones 3. Volume 1 is running from right to left horizontally through the device. In the end, behind the last one Cooling zone 3, the device is through a water cup 4 through which the belt 1 is guided by means of an immersion roller.
