Definitions

  • the invention relates to an arrangement of a storage device in a strip mill for hot rolling metal workpieces, in particular slabs, consisting of a roughing mill and a downstream finishing mill with the associated roller tables, with a winding station and an unwinding station for the strip rolled in the roughing mill between the roughing and finishing mill are arranged in a holding station and the rolling lines of the roughing and finishing train are offset from one another.
  • finishing train In order to achieve the high road performance we are striving for today, the finishing train will be designed as a unit of 5 to 7 individual stands, each of which will only produce one pass.
  • the object is achieved in such a way that the unwinding station is installed permanently in the rolling line of the finishing train and a transverse transport device is arranged between the winding and unwinding station, the outlet roller table behind the reversing roll stand under the holding station with the using a reversing roll stand in the roughing train Winding station and the transverse transport device is extended through.
  • the wound-up rings can be transported using a separate transport trolley which runs between the winding and unwinding station, i. H. Separation of the winding, transporting and unwinding functions.
  • This trolley also serves as a buffer, which can also compensate for time disturbances in the rolling mills.
  • the reel design and arrangement enables the first reel (or the transverse transport device) to be passed underneath, behind which corresponding roller tables are attached. This means that higher ring weights can be rolled in a shorter space, which further increases the performance of the street and reduces the amount of hall space required.
  • An embodiment can be constructed in such a way that the roughing and finishing lines are offset from one another in a Z-shape.
  • a very compact embodiment is characterized in an advantageous manner in that the roughing and finishing lines are arranged in a U-shape with respect to one another.
  • FIG. 1 to 4 show a rolling mill for metal slabs, which consists of a roughing mill 1 and a downstream finishing mill 2 with its associated roller tables 3, 4 and 5 which are offset from it.
  • a warming station 7 with a winding station 8 and an unwinding station 9 for the strip rolled in the roughing train 1 is arranged between the roughing train 1, which consists of a reversing roll stand 6, and the finishing train 2.
  • the unwinding station 9 can be moved transversely from the rolling line of the roughing train 1 into the rolling line of the finishing train 2, as shown in FIGS. 1 to 3.
  • Fig. 4 shows, on the other hand, that the unwinding station 9 is permanently installed in the rolling line of the finishing train 2 and between the winding station 8 in the rolling line of the roughing train 1 and the unwinding station 9, a transverse transport device 10 is arranged, which is also a buffer between the roughing train 1 and the finishing train 2 can serve, it being possible for coils to be located in the winding station 8, on the transverse transport device 10 as a waiting station and in the unwinding station 9 at the same time.
  • FIG. 1 shows that the roughing mill 1 and finishing mill 2 are offset in a Z-shape can be, whereas a U-shaped arrangement is shown in FIG. 2, which means a very compact rolling mill.
  • the landing of the slabs and the dispatch of the finished material can be concentrated in one place, press water generation station and supply systems can be arranged centrally with a short distance from the rolling and auxiliary units.
  • the possible rollable strip length can be increased if the outlet roller table 4 behind the roughing mill 1 is extended 11 under the warming station 7 with the winding station 8, as shown in FIG. 3.
  • the strip rolled in the roughing train 1 by means of the reversing roll stand 6 can pass under the warming station 7 with the winding station 8 in all passes before the finish stitch. Only the tape coming from the finish stitch in Vor No 1 is wound up in the winding station 8.
  • the rolling process in the rolling mill according to the arrangement according to the invention takes place in such a way that the strip running out of the roughing mill 1 is coiled up in the winding station 8, passed directly to the unwinding station 9 (FIGS. 1-3) or via the transverse transport device 10 (FIG. 4) and uncoiled from the unwinding station 9 and guided into the finishing train 2.
  • the strip coiled in the winding station 8 is transferred to the transverse transport device 10, which then transports the coiled strip transversely into the rolling line of the finishing train 2 and transfers it to the unwinding station 9 permanently installed there .
  • the take-up station 8 is immediately ready to take up the following tape once the reeled-up tape has been delivered to the take-off station 9 or the transverse transport device 10.
  • Rewinding station 8 unwinding station 9 and transverse transport device 10 are arranged in the warming station 7 so that the strip to be wound up to be transversely transported and unwound is kept at the rolling temperature.
