Definitions

  • the invention relates to a system for rolling thick and thin wire with the features specified in the preamble of the independent claim.
  • both thin wire - with diameters of up to about 20 millimeters - and thick wire - with diameters of up to about 50 millimeters - are subjected to various cooling processes after leaving the finishing train of a rolling mill.
  • the so-called Stelmor products, and thick wire, the so-called Garrett products include either standard or forced cooling, e.g. for medium to high carbon carbon steels and austenites, delayed cooling, e.g. for low carbon carbon steels, screw steels, spring steels and welding wires, or slow cooling, e.g. for tool steels and high-speed steels.
  • Stelmor cooling is known for thin wire, in which the wire product fanned out in turns on a conveyor with the aid of cooling air and open or closed or partially open and partially closed lids of the cooling section or is cooled by means of holding pots.
  • the cooling of thick wire wound into bundles can be achieved in the ambient air or by plasticizers in the area of the longitudinal transport of the cooling section, by using water reels, putting on insulated hoods, using warming pots or in isolation chambers. In this way, it is possible, especially when a large range of quality is desired, such as in particular for stainless steel products, to provide cooling that meets the requirements of the product.
  • the round steel production line of this known wire rolling plant is a coil forming device or a reel for both round steel and wire dimensions.
  • the bundle forming device and the Stelmor line are connected to one another by a transverse transport device. This does provide a certain degree of networking and thus a flexible mode of operation, but without achieving a compact networking of different cooling sections or processes by means of coordinated means of transport and cooling processes.
  • the invention is therefore based on the object of creating a generic wire rolling system which enables the various cooling sections or cooling processes to be networked with the least possible structural outlay.
  • switches arranged behind the finishing lines guide the wire to reels, to which a parallel conveyor extending parallel to a cooling section for controlled wire cooling and converted into a cooling section for delayed and / or natural and / or forced cooling can be assigned.
  • the rolled wire regardless of whether it is thick or thin wire, is fed to the desired cooling process immediately after the rolling line, and is subjected to a desired cooling after coiling by inline treatment with integrated handling of the wire bundles.
  • the thick wire rolled in a steel bar mill is fed from the switch arranged between the cooling bed of the bar mill and the finishing block to an intermediate switch which, depending on the assignment, leads the thick wire either to one or the other reel, where this leads to Wire coils is wound, which are then distributed for cooling.
  • the cooling section downstream of the finishing train for the thin wire rod allows standard or forced cooling for the Stelmor products, which requires opening of the Stelmor lids, or controlled, delayed cooling, which requires closed or partially closed Stelmor lids, whereby all or just some of the fans can be out of order.
  • the longitudinal conveyor can be used to transport the warming pots filled with bundles of either thick or thin wire to suitably equipped storage locations.
  • the longitudinal conveyor be connected to the reels via walking beam conveyors.
  • the bundles with thick wire dimensions wound in the Garrett reels are either deposited directly on the longitudinal conveyor or on pallets that have previously been positioned on the longitudinal conveyor via the walking beam transports.
  • a warming pot is placed over the collar.
  • the entire unit, consisting of a pallet and a hot pot, including the collar, is transported by longitudinal transport to the storage area for slow cooling, where it is removed by crane and placed on the side.
  • the bundles can also be used without pallets and warming pots are conveyed away and, if necessary, subjected to a delayed cooling during transport on the longitudinal conveyor, for which purpose the longitudinal conveyor can have insulated hoods covering the conveyor path in the manner of a tunnel.
  • the longitudinal conveyor is connected to the cooling section for controlled wire cooling via a first cross conveyor.
  • the cross conveyor on the one hand, can then lead to tong transport routes starting from the reels.
  • the tongs transport routes ensure that bundles with large coil heights and steel qualities such as Lead or sulfur alloyed free-cutting steels, which tend to fall apart due to their special scaling and would therefore be difficult to transport on a conveyor belt, can be handled and fed to the longitudinal conveyor without any problems.
  • the first cross conveyor can be connected to a second cross conveyor crossing the cooling section via an intermediate conveyor running parallel to the cooling section.
  • mandrels can be used to transport pallets, which have been loaded with a transport trolley, via the intermediate conveyor to the first cross conveyor, which is located in the immediate vicinity of the winding section of the finishing train for thin wire dimensions.
  • a bundle forming chamber into the cooling section, it is possible to collect the falling wire windings over the mandrel pallet to form a bundle, which - when a warming pot is subsequently placed on it - reaches the longitudinal conveyor, from where it is then removed by a crane and can be distributed to the storage bins.
  • a wire rolling plant 1 shown in the drawing.
  • This consists of the finishing train 2 for rolling thin wire and the finishing train 3 - not shown in the drawing Rolling thick wire.
  • a switch 5 Following the finishing train 3 and well ahead of a cooling bed 4 is a switch 5 which feeds the thick wire running out of the finishing train 3 to an intermediate or distributor switch 6. This alternately feeds the thick wire 7 to one of two Garrett reels 8.
  • the finishing train 2 for thin wire is followed in a line by a cooling section 9 for controlled Stelmor wire cooling. It is provided with numerous, not shown fans and hoods 11, of which - depending on the desired cooling - either all or only a few can be closed; in the same way, all or only a few of the fans can be in operation.
  • a longitudinal conveyor 12 assigned to the reels 8 extends parallel to the cooling section 9 for standard or forced cooling and delayed wire cooling.
  • the longitudinal conveyor 12 extends with its end facing the finishing lines 2, 3 to the reels 8 and is connected to them via walking beam conveyors 13.
  • the reels 8 are also connected via tongs transport routes 14 to a first cross conveyor 15, which is also linked to both the Stelmor cooling route 9 and the longitudinal conveyor 12.
  • An intermediate conveyor 16 running parallel to the cooling section 9 connects the first cross conveyor 15 to a second cross conveyor 17, which crosses the cooling section 9 below its transport plane, like the intermediate conveyor 16 designed as a conveyor belt.
  • the thin wire leaving the finishing train 2 and entering the Stelmor cooling section 9 is fanned out in turns by means of a winding layer 27 on the transport rollers of the cooling section 9 and is subjected to standard or forced cooling or delayed cooling during its transport, the latter being the case all or only some of the hoods 11 of the cooling section 9 are closed and no or only a few fans are in operation. If, on the other hand, a very slow cooling is to be carried out, the transport trolley 26 takes the pallets 21 provided with thorns from the storage location 18 and sets them down on the second cross conveyor 17, from where they move via the intermediate conveyor 16 to the first arranged near the winding layer 27 Cross conveyor 15 arrive.
  • a bundle of wires collected on the mandrel pallet 21 is then covered with an empty holding pot 24 which is placed on the mandrel pallet 21 by means of a crane and thus envelops or encapsulates the bundle of wires.
  • the cross conveyor 15 then transports the mandrel pallet 21 provided with the holding pot 24 onto the longitudinal conveyor 12, and at the end of the pallet is removed by a crane and transported to the storage bins 23, where the bundle of wire can then cool for several hours if necessary.
  • Thick wire 7, which leaves the finishing train 3 and is fed from the switches 5, 6 to the reels 8, can either be cooled in the ambient air or supported by fans on the longitudinal conveyor 12 normally or forcedly by using water reels.
  • the path of the wire coils from the reels 8 via the walking beam conveyor 13 to the longitudinal conveyor 12 is also observed if the wire coils are to be cooled with a delay in the area of the longitudinal transport; this can be achieved by means of an insulation tunnel 28, which is dash-dotted in the drawing and is formed by placing insulated hoods on the longitudinal conveyor 12.
  • the cooling section 9 arranged in a line behind the rolling mill 2 for thin wire is thus compactly networked via the transverse conveyors 17 and 15 and the intermediate conveyor 16 with the longitudinal conveyor 12 which can be variably configured for cooling purposes. Since, in addition, walking beam conveyors 13 lead from the reels 8 to the longitudinal conveyor 12 or - in the case of the rolling of, for example, lead or sulfur-alloyed free-cutting steels - tongs transport routes 14 are connected to the longitudinal conveyor 12 via the first cross conveyor 15, it is ensured that both the thin and thick wire can be fed to its destination according to the respective cooling process in the shortest possible way.
