Definitions

  • the invention relates to a rolling mill for rolling Flat steel using universal frames with instead of Vertical rollers arranged in their stand area, adjustable Carriers of pairs of loose vertical rolls.
  • 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, starting from the described State of the art, the known, from a roughing group with vertical dual scaffolding or universal scaffolding and horizontal dual scaffolding and a compact rolling 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, preferably continuously cast Raw profiles are used, another application assign.
  • roller mill from one Roughing group with vertical duo stand or universal stand and horizontal duo stand and one of these downstream from two tandem universal stands existing compact rolling group at which the two universal stands of the compact rolling group with non-driven ones adjustable vertical rolling rollers are.
  • Such rolling mills 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 groups simultaneous exposure to the side edges of the profile the vertical rolling rolls, which initially form the edges and later edge-guiding, finish-rolled.
  • the tandem universal stands can also have two or more universal finished 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 rollers can in the adjustable vertical bearing chocks of the universal scaffolding be stored; the vertical rolling rolls, caliber incisions adapted to the side edges of the flat steel profile exhibit.
  • the vertical rolls VWR 2 'and VWR 2' 'can be a K caliber have (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.
  • 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 the resulting profile in the first tandem universal scaffolding 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 applied, also in the following stitch 4 in second tandem universal scaffold TUF. Then two more follow 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 manufactured 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.
