  • Rolling devices of this type are well known in the art. On them, for example, flat material in sheet and / or strip form of steel or non-ferrous materials can be produced.
  • a metal strand may be poured, which is passed as a slab through a roughing train (first rolling device) and then through a finishing train (second rolling device), where the finished product is rolled from the slab. Subsequently, a post-processing of the rolled Guts, in particular a cooling, coiling or possibly a hot dressing.
  • the slab can first be heated in an oven to rolling temperature and then rolled by means of a rolling sequence, which may also include 90 ° turning of the rolling stock in a single or multi-stand rolling mill to the desired sheet metal dimensions.
  • a rolling sequence which may also include 90 ° turning of the rolling stock in a single or multi-stand rolling mill to the desired sheet metal dimensions.
  • Especially turning devices for the material to be rolled for example, from the DE-OS 14 52 161 and from the DE-OS 16 52 560 known.

  • long continuous casting slabs are rolled without turning on a Steckel puzzle by winding the rolling stock between the finished passes in heated Steckel ovens on large end lengths, which are either wound after the last stitch into coils or divided by a pair of scissors into individual sheets.
  • the individual sheets can be cooled and straightened.
  • the Steckel rolling process has several advantages in processing a pre-rolled slab into a metal strip. It should be emphasized that the rolling process can take place to a relatively thin strand in a relatively small space.
  • the invention is therefore based on the object, a device of the type mentioned in such a way that, especially when using the Steckel rolling process, a greater economic efficiency of the system is achieved.
  • the solution of this object by the invention is characterized by a conveyor, taken with the metallic Good between the second region and the third region of the device, transported and between the third region and the fourth region of the device can be supplied to the processing process again.
  • the concept of the invention is therefore based on the fact that only the first rolling device (ie the roughing train) is used for the use of the production plant waiving the rolling in the second rolling device (ie on the finishing train), in which case - to the aftertreatment devices for only on the To be able to use rolled material well first rolling device - the pre-rolled material is conveyed parallel to the second rolling mill under their circumvention and fed back to the processing process before the aftertreatment device.
  • the second rolling device is a Steckel rolling device which has at least one rolling stand, upstream of a first furnace in the flow direction of the metallic Guts and a second furnace is arranged downstream. The Steckel rolling process is then carried out on this device.
  • the aftertreatment device preferably has a cooling device for the rolled product.
  • the conveying device for bypassing the second rolling device can have a roller conveyor which is arranged parallel to the second rolling device. Furthermore, the conveying device can have at least one, preferably two, means with which metallic material can be conveyed transversely to the flow direction of the material. Thus, the pre-rolled material in the first rolling device can be conveyed in the manner of a bypass of this directly to the aftertreatment plant.
  • a continuous casting plant is provided in the first region of the device.
  • a slab bearing can be arranged in the first region or in the second region of the device.
  • at least one heating furnace for the roll to be rolled is preferably between the slab bearing and the first rolling device Well arranged (preferably two ovens) to bring this to the optimum rolling temperature.
  • a descaling device may be arranged between the at least one heating furnace and the first rolling device.
  • the economy of the manufacturing process can be significantly increased, since the first rolling device during the Steckel rolling (in the second rolling device) can be used for other good, which is then treated directly in the aftertreatment plant ,
  • Fig. 1 is a manufacturing device to see, is produced or processed with the metallic Good 1.
  • the device has essentially four areas 2, 3, 5 and 7, which adjoin one another in the direction of flow F of the metallic material.
