Definitions

  • the invention relates to a method for rolling broadband raw material, a raw slab being rolled to the intended broadband width by upsetting the narrow sides.
  • standard material graded according to the intended bandwidth is usually used in broadband lines.
  • the grading of the raw material can either be done by casting raw slabs of different widths or by strong upsetting, i.e. Reducing the width of raw slabs of uniform cross-section can be effected. Both methods are associated with considerable disadvantages.
  • the object is achieved according to the invention in that a raw slab with a cross-section tapered on both sides in the form of a wedge or curve to the narrow sides is compressed to approximately the intended broadband width while filling the rectangular shape.
  • the width of the raw slab is reduced without bulges on the broad sides of the slab, so that spreading back during flat rolling is avoided.
  • the required width reduction can usually already be achieved with a compression stitch. This saving on compression stitches and flat rolling stitches saves time and energy. Since the new process no longer forms a fish tail at the end of the primary material, the amount of scrap is reduced considerably.
  • raw slabs produced by continuous casting can be used in the method according to the invention.
  • the continuous casting of the slabs which are tapered in a wedge or curve shape on both sides to the narrow sides without mold adjustment, leads to higher productivity with less investment.
  • a raw slab 1 with a rectangular cross section according to FIG. 1 is compressed by a swaging roll stand 2 according to FIG. 2 from width a to width b.
  • the bulges 4 must be smoothed in the downstream horizontal roll stand 5 by a flat stitch. This results in a return of 2r.
  • a raw slab 6 according to FIG. 3 is used, the broad sides 7 of which have angled outer regions 7a which taper the cross section to the narrow sides 8 of the slab.
  • the upset material 10 fills the edges 11 up to the rectangular shape of the slab. There are no bulges on the broad sides 7, so that subsequent flat rolling with the disadvantage of the back spreading of the slab can be omitted.
  • the raw slab shown in FIG. 3 can be reduced to the intended bandwidth on the upsetting roll stand 9 without flat passes on a horizontal roll stand in a upsetting pass.
  • a special horizontal roller Setting up for rolling flat bulges is therefore saved
  • the special shape of the raw slab 6 can preferably be produced by continuous casting.
  • the method cannot only be carried out with the blunt-wedge shaped slab shape shown in FIG. 3.
  • the aim of the invention can also be achieved with a raw slab that is tapered on both sides.
