Definitions

  • the invention relates to a rod and wire rolling mill with an associated Cooling bed line for bars, a rotating basket reel line for rods wound into coils and a wire line with a loop layer and winding collectors for wire with downstream heating furnaces for thermal post-treatment of the feed material leaving the rolling mill.
  • Rod and wire rolling mills of this type are known. Here either Rolled, cut, chilled and bundled or rolled bars Bars wrapped in rotary basket reels, cooled and bundled or else Wire laid in coils, collected into wire bundles and cooled then bound.
  • rod and wire lines can be used. Become however e.g. Cold-work steel or high-speed steel rolled and the appropriate lines fed, so these must be in contrast to other processes without thermal intermediate or aftertreatment, such as. cooling isothermally over a longer period of time to achieve a desired material structure or until it is reached convert desired material properties.
  • the invention is therefore based on the object of a generic Rod and wire rolling mill so that in addition to the normal Steel grades can also be rolled over a steel longer periods of time need to be treated isothermally take up little space and are inexpensive to produce.
  • the transport device Rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets has, and that in the cooling bed line, the rotary basket reel line and the wire line transfer stations are provided by means of or the rolling stock to the rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets can be transferred and via this the Holding oven can be fed.
  • the transfer station ensures that the rod material or the wire is removed from the corresponding line and over the rod collection boxes, rotary basket reel coil pallets and wire coil mandrel pallets fed to the holding furnace can be.
  • insulated tunnel storage is assigned to the transport device, so the rod collection boxes and pallets can be kept in the holding furnace heat up and store on demand in the storage tanks. Stand there thus always for the rolling stock to be introduced into the holding furnace heated rod collection boxes or pallets available.
  • the usage heated rod collection boxes and pallets is special Significance to prevent the rolling stock from touching any cold spots on the rod collection boxes or pallets themselves is partially cooled too much and cold at the points of contact Get jobs that may not be the one you want later Show structure. Because the rod collection boxes and Pallets are heated and stored in the heated state can, it is achieved that the rolling stock even when loading the boxes or pallets remains at an even temperature.
  • roller tables can be designed as heat-insulated roller tables on the one hand, the temperature loss as possible on the transport routes keep it small, but also the roller tables as storage roller tables to be able to use.
  • Figure 1 shows a billet heating furnace 1, which the profile frame groups Connect 2, 3, 4, with a different Number of rollers used in these stand groups 2, 3, 4 different thickness material such as rod material or wire material can be rolled.
  • the scaffolding group 4 divides the rolling line 5 into a cooling bed line 6, a rotary basket reel line 7 and a wire line 8 with a loop layer 9, a cooling bed 10 and a winding collector 11.
  • Fig. 2 are the cooling bed line 6, the rotary basket reel line 7 and the wire line 8 recognizable.
  • the to the cooling bed line 6 points essentially a cooling bed 12 on.
  • the bars are one of the cooling bed 12 Bundling station 13 via a pair of scissors 14 in which the rods are of commercial length are cut and a transverse transport 15 can be fed.
  • the rotary basket reel line 7 has drivers 16, 16 'and rotary basket reel 17, 17 '.
  • One is connected to the rotary basket reel 17, 17 ' Transfer station 18, by means of which the rods wound into coils of the two rotary basket reels 17, 17 'onto a longitudinal transport device 19 are transferable.
  • a tilting chair 20 is provided, by means of which the bundles of rods can be tilted and can be transferred to a hook track 21 in order from this to the binding press 22 to be spent.
  • the wire line 8 is the loop layer 9, the Stelmor cooling bed 10, the winding collector 11 and a tilting chair 23 shown also cooperates with the hook track 21 and the binding press 22.
  • the cooling bed line 6 is a transfer station 24 for transferring the Rods on rod collecting box movable on a transport device 25 27 assigned, with scissors 26 the rods to lengths is able to cut the inner dimensions of the rod collection boxes 27 correspond.
  • the transfer station 18 in the rotary basket reel line 7 is also capable of the rods wound into bundles to be delivered to pallets 28 of the transport device 25.
  • Over a Transfer station 29 in the wire line 8 is the winding Wire can be collected on a mandrel pallet 30 and sent to the transport device 25 transferable.
  • the transport device 25 consists of rotating roller tables 31, on which the rod collection boxes 27, the pallets 28 and the mandrel pallets 30 are movable.
  • the transport device 25 serves to the rods or bundles of rods or wire bundles, but also the empty ones Rod collection boxes 27, pallets 28 and mandrel pallets 30 a holding furnace 32 feed.
  • the rolling mill shown in FIGS. 1 and 2 becomes Rolling, dividing, cooling and bundling of common steel grades used.
  • isothermal treatment e.g. Rods by means of the transfer station 24 into previously heated in the holding furnace 32, over the roller tables 31 to the insulated tunnel storage 33 and rod collecting boxes 27 conveyed by the latter to the transfer station 24 filed.
  • the rod collection boxes 27 loaded with rods become Keep heating oven 32 and here the required isothermal Undergone treatment.
  • the transfer station 29 activated. For this purpose, part of the Stelmor cooling bed 10 is made the wire line 8 shifted and for this a winding collector 11 ' its place set. Under the winding collector 11 'is the storage roller table 31 performed on the preheated and, if necessary on the storage roller table 31 temporarily stored mandrel pallets 30 are provided and the wire turns coming from the winding collector 11 ' able to absorb. About the storage roller table 31 that Wire bundle transferred to the holding furnace 32.
