Definitions

  • the invention relates to a method for rolling profiled Rolling strands in a roll stand arrangement consisting of a first and a second universal scaffold or duo scaffold and one between these scaffolds arranged intermediate compression frame, behind which an outfeed roller table is arranged laterally to this arranged cooling bed, in which the Pre-profile rolled strands from a continuous casting device in one, of whose Power exiting a certain time cycle, fed to the roll stand arrangement, in a plurality of stitches and reversing stitches are rolled onto the Spout roller table applied and from this to a laterally arranged cooling bed getting deported.
  • This arrangement allows the rolling mill to be timed to operate continuously with the continuous casting device when the from the rolling mill performed the shaping of the preliminary profile in the finished rolled strand same or a shorter period of time, which also the continuous casting device needs to create a preliminary profile.
  • the unit of length of the finished strand to be formed is the temporal performance of the Roll stand arrangement smaller, d. H. for the finish rolling of profiled Rolls of rolled material are required the more time, the smaller the finished profile cross-sections to be achieved are because a correspondingly increasing number of Stitches and reversing stitches are required in the compact rolling group, and by a certain profile size, the performance of the roll stand arrangement is not sufficient more from processing the production of the continuous caster in time. It then need elaborate interim storage, of the continuous casting produced pre-profiles.
  • the mentioned from the Continuous casting device predetermined period of time between, by this successively applied pre-profiles therefore sets for the size of the with Compact rolling group of millable finished cross sections a limit. Smaller, below finished profiles within this limit cannot be rolled.
  • the invention has for its object to eliminate this limit and the Possibility to create profile cross-sections with the rolling mill described to roll whose size is below this limit.
  • the described method can also be different so that the finished rolled, placed on the outlet roller table Rolled material strand with a rear section placed next to the cooling bed, behind this divided and the divided rear applied to the cooling bed and immediately afterwards the front section of the rolled material strand through the Discharge roller table back next to the cooling bed, be applied to this, and that during the first application process the one from the Continuous casting device coming following pre-profile rolling stock in the Roll stand arrangement introduced and the rolling of which is started.
  • the roll stand system consists of the Feed roller table R1, which, from the universal stands UG1 and UG2 and the existing compact rolling group between these intermediate stands, which this downstream discharge roller table R2 and the side this Discharge roller table R2 and the cooling bed KB arranged on the side of the rolling line WL as well a separating device TR located in front of the cooling bed KB.
  • the mill stand is operated in such a way that the first one PSTI finished rolling strand leaving the compact rolling group on the Removal roller table R2 is moved in front of the cooling bed and brought to a standstill. Then, with the help of the separating device TR, the KB in front of the cooling bed lying first length section PSTI 'separated and applied to the cooling bed. Then the second is still on the discharge roller table R2 Length section PSTI "in front of the cooling bed KB and also on this upset. In the meantime, the following became (not shown) Preliminary profile created by short reversing stitches next, in broken lines indicated rolling stock strand PSTII on the discharge roller table R2 applied and divided accordingly after its finish rolling and the The resulting lengths are applied to the cooling bed.
  • FIG. 2 corresponds in principle to that of FIG Fig. 1 with the proviso that the cooling bed KB in one, approximately the length of a Length section of a divided rolling stock correspondingly smaller Distance from the compact rolling group is arranged, and the separating device TR here, seen in the WL rolling line, behind the cooling bed.
