Definitions

  • the invention relates to a device for stabilizing the running of a metal strip in a galvanizing plant, hot-dip galvanizing plant or Feueralum iststrom.
  • the unpainted metal strip first passes through a series of treatment steps in which the strip is cleaned and heat treated before immersing in a zinc bath for galvanizing.
  • the zinc bath has a pulley and stabilizer rollers that support the belt.
  • the tape exits the zinc bath whereupon excess zinc is blown off the belt through nozzles.
  • the belt runs in a 30 to 50 meter long cooling section before it is again led to a leadership role.
  • unwanted vibrations occur that can not be compensated by the stabilizing rollers in the zinc bath. Due to the vibrations occurring, it is not possible to maintain a minimal zinc layer, but rather the strip is galvanized by the vibrations.
  • the invention has for its object to make the arrangement of electromagnets and distance sensors so that a simple coating and reliable adjustment a homogeneous coating is achieved.
  • Fig. 1 shows schematically a galvanizing plant with a furnace 1, through which a metal strip 4 is guided, before it dips into a zinc bath 2.
  • the band 4 is deflected by a bath roller 3 in the direction of a cooling system 9, the band 4 being supported by one or more positioning or stabilizing roller 5 before it leaves the zinc bath 2.
  • excess zinc is removed from the strip surface by blowoff nozzles 6.
  • a strip stabilizing device 8 is provided in order to adjust and stabilize the spacing of the strip in the transverse direction, as indicated by a double pier 7, between the blow-off nozzles 6, a strip stabilizing device 8 is provided.
  • Fig. 3 shows details of such a belt stabilizing device 8, wherein both sides of the belt 4 are arranged at a distance from this actuator in the form of electromagnet 10.
  • distance sensors 11 are provided on both sides of the belt 4, which measure the distance of the belt 4 from a predetermined center position and pass on the distance signals to a control electronics, from which the electromagnets 10 are driven on the two sides of the belt to a corresponding Apply force to the metal strip 4 transversely to its plane when the band position between the blow-off 6 must be corrected.
  • pole pieces 10 of electromagnets are arranged on either side of a row of distance sensors 11, the length of the row depending on the width of the band to be stabilized.
  • the electromagnets and distance sensors are arranged in a housing 12, which is covered on the band-facing side by a mica plate 12a for protection against the action of heat.
  • This heat shield 12a is cooled by air.
  • the housing 12 is preferably provided with a hinged cover 12b, as shown in FIG. 2.
  • FIG. 2 shows the nozzle structure 6 formed essentially of two nozzle bars 6a and 6b.
  • 6c designates tubes for cooling air.
  • the nozzle structure 6 with the nozzle bars 6a and 6b is predetermined by the respective galvanizing plant.
  • a support 13a, 13b is respectively supported with downwardly angled ends on a mounting member 14 which is mounted at the outer ends of the nozzle bars 6a and 6b.
  • Each support 13a, 13b carries a housing support 16 with housing 12, to each support a cross-sectionally L-shaped member 15 (Fig. 5) is attached to which a guide 17 is mounted for a cross-sectionally approximately T-shaped member 18 on which the housing support 16 rests and is fixed.
  • an electric motor 19 is preferably mounted in a housing which drives via a spindle 19a a pinion 19b, which is in engagement with a toothed rack 20 which is fastened to the approximately T-shaped component 18, as Fig. 6 shows in detail.
  • the housing support 16 can thus be moved along the component 15 in the guide 17 transversely to the nozzle gap to adjust the distance between the electromagnet 10 on the opposite sides of the belt 4.
  • an electric motor 19 with the components 15 and 18 is respectively provided at the two ends of a housing support 16.
  • the nozzle assembly 6 (FIG. 2) is arranged to be adjustable at least in height relative to the zinc bath, with the entire structure mounted on the carriers 13a, 13b being moved together with the two housings 12 and 12 'during an adjustment movement of the nozzle assembly 6. Due to the adjustment movement of the nozzle assembly 6 is a positioning of the nozzle gap relative to Band made, which can be done by the electric motors 19, an adjustment of the electromagnets 10 with distance sensors 11 relative to the nozzle assembly 6.
  • a unit by a housing 12 is mounted with housing support 16 on a support 13a and 13b.
  • the so prefabricated shown in Fig. 5 structure can be placed on the mounting components 14 and 14 'preferably fitted and secured by screws or quick-release fasteners 13d, so that overall results in a very short assembly time.
  • a bolt engaging in a bore can be provided.
  • brackets 13a and 13b are respectively provided at the ends with two spaced end portions 13c, each of which is provided with a connection means, for example, a quick-release closure 13d for mounting on the mounting members 14.
  • the separate, preferably made of stainless steel housing 12 are preferably provided with an air cooling.
  • five pairs of actuators or magnets 10 are arranged on each side for a bandwidth of about 1.3m in each housing, wherein the sensors 11 are arranged between the respective pairs of actuators.
