Definitions

  • the invention relates to a rolling mill for rolling Flat steel behind a roughing group one, from two universal scaffolds arranged in tandem has existing compact rolling group in which the horizontal rolls of the universal scaffolding, loosely supported Vertical roller pairs are upstream and downstream.
  • the roughing on the duo reversing roughing stand with one for Profile rolling requires a large bale length in terms of rolling force and rolling tolerances due to the strong deflection of the Rollers limited.
  • the required high number of stitches leaves you Group operation with a corresponding slab / continuous casting plant not to.
  • the temperature conditions also limit the number of Stitches in the roughing stand and thus the achievable final thickness, which as Tapping thickness must serve for the following universal rolling and therefore makes more rolling work necessary for this.
  • the bigger ones Roll thicknesses that are generated in the duo reversing stand can not sufficiently compressed at the edges during roughing as is the case with wide flat steel or universal wide flat steel is desirable.
  • There is an upsetting in the duo reversing stand only possible as long as roll thickness and roll width can be raised allow the flat profile and its upright upsetting.
  • the invention is based on the object the well-known, from a roughing group and a compact roller group with at least two universal stands existing rolling mills, which so far, together with additional compression stands primarily for the rolling of Beams and other profiles another application, namely that of simple rolling of flat steel accessible close.
  • This roller mill can e.g. be operated so that the Raw profile in the vertical stand or universal stand of the roughing group compressed and then in successive stitches and Reversing stitches in the tandem stands of the compact rolling group simultaneous action on the side edges of the profile the vertical rolling rolls, which initially form the edges and later edge-guiding, finish-rolled.
  • roller mill according to the invention can also have two or more universal finishing stands be subordinated.
  • Such a rolling mill can do so operated that the profile in the tandem universal scaffolding the compact roller group after the successive passes Subject to reversing stitches, but directly to the subordinate ones Universal finishing stands supplied and in these, also without Reversing stitches are finished rolled.
  • the vertical rolling rolls VWR 2 'and VWR 2 "have a caliber K. on (Fig. 3).
  • This caliber K with a better edge formation of the rolled steel strand WG can be produced for the first pass of the rolling stock WG in the direction of arrow F. the respective thickness reduction first in the tandem universal scaffolding TUR and then be coordinated in the tandem universal scaffold TUF. In the following passes and reversing passes this caliber K then only serve the lateral guidance of the rolling stock WG.
  • Fig. 4 is a raw profile VP with a rectangular Cross section in the vertical duo scaffolding VDG in a first stitch 1 compressed and then in another stitch 2 in the horizontal duo scaffolding HDG rolled rolled to a dimension that the introduction of the resulting profile in the first tandem universal scaffold TUR the compact rolling group allowed in one pass 3.
  • this stitch the two side edges of the profile through the vertical roller pairs VWR acted, also in the following stitch 4 in second tandem universal scaffold TUF.
  • Reverse stitches R5 and R6 in the opposite direction through both Scaffolding, and these are followed by the final stitches 7 and 8.
  • stitch 8 in the last tandem universal scaffold TUF that is then Flat rolled steel products are rolled.
  • FIG. 5 differs from that of FIG. 4 only in that in the roughing group instead of the vertical duo stand a universal scaffold UG is used with its help the pre-profile VP pre-rolled in the first pass 1 and then in following stitch 2 in the horizontal duo stand HDG of the roughing group is spread.
