Definitions

  • the invention relates to a device for the heat treatment of steel wire, in which the wire, after it emerges from a continuous wire rolling mill, is placed by a winding layer on a horizontal conveyor, and is further transported thereon in the form of a series of successively overlapping turns, surface-treated during transportation, at the end of the conveyor from a winding collecting device to a wire bundle and transferred to a coil transport device.
  • the invention has for its object to improve the generic device so that the wire emerging from the wire rolling mill can optionally be subjected to one of the treatment methods listed above, without having to interrupt the rolling operation.
  • a second winding collecting device that can be inserted and removed behind the winding layer in the transport path of the horizontal conveyor, the associated coil transport device of which has selectively actuatable transfer devices for transferring the wire bundles to coil heating devices or coil cooling devices.
  • the horizontal conveyor can have behind the winding layer a conveyor section that can be moved out of the transport path and can be replaced by the winding collecting device, and the coil transport device can consist of a transverse conveyor for empty coil pallets that are to be inserted into the winding collecting device and, after being loaded with the respective wire bundles, they have to be taken out of the coil receiving pallets.
  • the transport plane of the cross conveyor runs below an optionally operable device for placing thermal insulation hoods on the coil receiving pallets loaded with wire bundles and brought out of the winding collecting device.
  • the cross conveyor can be assigned in the direction of transport behind the device for placing the thermal insulation hoods a lifting device for the lateral depositing of the bundle receiving pallets with the wire bundles covered by thermal insulation hoods in a thermally insulated, coverable and heatable collective store.
  • the cross conveyor can also be assigned a lifting device for the lateral placement and immersion of the bundle receiving pallets with the wire bundles in a water bath behind the device for fitting the thermal insulation hoods in the transport direction.
  • the devices for the lateral depositing of the bundle receiving pallets into a storage tank or a water bath can expediently be arranged on the side of the cross conveyor facing away from the winding layer and, associated with them intermediate conveyors, running parallel to the horizontal conveyor, in each case before, arranged above, and above a common second cross conveyor and transfer devices , which transfer the coil of wire to a further transport device, and places the associated empty coil receiving pallet on this second cross conveyor, which is connected to the first cross conveyor by a further intermediate conveyor.
  • the device according to the invention allows the wire emerging from the wire rolling mill, after it has been placed in the form of successive overlapping turns on the horizontal conveyor, to be heat-treated on the conveyor by means of air or spray water and then to be introduced into the winding collecting device arranged at the end of the horizontal conveyor and to remove the bundle of wire formed therein.
  • the wire emerging from the wire rolling mill can also be collected into a bundle of wires in the bundle collecting devices placed directly behind the winding layer in the transport path of the horizontal conveyor, applied to a bundle receiving pallet, transported by the cross conveyor under the device for placing thermal insulation hoods, either covered with the thermal insulation hoods the lifting device for the lateral depositing of the bundle receiving pallet into a bundle of wire bundles or the lifting device for the lateral depositing of the bundle receiving pallet with the bundle of wire into a water bath.
  • the drawing shows the device in perspective.
  • the wire D arriving from the continuous wire rolling mill (not shown) in the direction of arrow S first passes through a pre-cooling device V and then passes into the winding layer WL, which deposits the wire D on the horizontal conveyor HF in successively overlapping turns, also not shown.
  • a winding collecting device WS 1 At the end of the horizontal conveyor HF there is a winding collecting device WS 1 in the form of a vertical collecting shaft.
  • the horizontal conveyor HF behind the winding layer WL is interrupted by the fact that a horizontal conveyor section HFA is moved laterally out of the transport path and a second winding collecting device WS 2 has been introduced into the transport path in its place.
  • a cross conveyor QF 1 is arranged below the horizontal conveyor HF, the transport path of which runs transversely to the transport path of the horizontal conveyor HF; it is intended for receiving and transporting bundle receiving pallets 2, which here have a vertical collecting mandrel.
  • a feed conveyor ZF for the thermal insulation hoods 1 is arranged above the cross conveyor QF 1 and runs parallel to the horizontal conveyor HF. At the end of this feed conveyor ZF, in front of the cross conveyor QF 1, there is a placement device 3 for the placement of the bundle receiving pallets 2 on the cross conveyor QF 1 with the wire bundles DB.
  • An intermediate conveyor 4, which ends in front of an immersion bath 5, is located on the side of the cross conveyor QF 1, specifically on the side facing away from the winding layer WL.
  • This intermediate conveyor 4 is assigned a lifting device, not shown, for introducing the bundle receiving pallets 2 with or without attached thermal insulation hoods 1 and for removing them from the immersion bath 5. Further on this side of the cross conveyor QF1 there is also a storage tank 6 in the form of a pit which can be closed with movable covers 7. The coil receiving pallets 2 on the cross conveyor QF 1 with the wire coils and the thermal insulation hoods 1 covering them can be inserted into and brought out of the pit 6 with the aid of a lifting device, not shown, on a cross intermediate conveyor 8 will.
  • a second cross conveyor QF 2 is arranged parallel to the first cross conveyor QF 1, the transport path of which runs below the horizontal conveyor HF.
  • This second cross conveyor QF 2 is assigned in the areas behind the immersion bath 5 or the collective store 6, not shown, transfer devices for the bundle receiving pallets 2 brought out of the immersion bath 5 or the collective store 6 with the wire bundles DB and possibly the thermal insulation hoods 1 and bundle transfer devices 9. These coil transfer devices 9 lift the wire bundles DB from the coil receiving pallets 2; hook conveyors 10 are arranged after them.
  • the cross conveyor QF 2 ends in a further cross conveyor QF 3 which is connected to the first cross conveyor QF 1 with the interposition of a lifting device 11.
  • the windings treated in this way are collected in the winding collecting device WS 1 to form a wire bundle DB, which results from this is passed to the downstream hook conveyor 10.
  • the horizontal conveyor section HFA has been pushed into the transport path of the horizontal conveyor HF from the position shown in the drawing in a manner not shown.
  • the horizontal conveyor section HFA is moved laterally out of the transport path of the horizontal conveyor HF and the winding collecting device WS 2 is inserted in its place into the transport path of the horizontal conveyor HF.
  • the windings placed by the winding layer WL on the horizontal conveyor HF are then collected in this winding collecting device WS 2 to form a wire bundle DB on the bundle receiving pallet 2 located in the winding collecting device WS 2 and also by the cross conveyor QF 1 into this brought position shown in front of the intermediate conveyor 4 and covered there with the aid of the attachment device 3 with a thermal insulation hood 1.
  • the bundles DB can then either be introduced from this position via the intermediate conveyor 4 into the immersion bath 5 and then applied to the hook conveyor 10 via the belt transfer device 9, or positioned on the cross conveyor QF 1 in front of the accumulator 6 and with the aid of the lifting device (not shown) inserted into the accumulator 6 and, after completion of the heat treatment, fed from the latter via the transverse intermediate conveyor 8 to the coil transfer device 9 and from there to the hook conveyor 10.
  • the thermal insulation hoods 1 removed in the belt transfer device 9 from the coil receiving pallets 2 and the wire bundle DB are fed to the cross conveyor QF 1 for further use in the winding collecting device WS 2 with the aid of the second cross conveyor QF 2 and the further intermediate conveyor QF 3.
