Definitions

  • the invention relates to a continuous casting plant for producing thin slabs, comprising an oscillating continuous mold which has a strand guide, drive rollers, a bending roller and a support roller are connected downstream, the bending roller one Rigid cold strand conveyed vertically downwards, at the beginning of the casting process with a cross section essentially the mold cross section corresponding, with a bevelled end that ends in a wedge shape in the direction of strand extraction Compensation area trained, a lost on a cold strand head Head with start-up head closes the passage mold, below decouples the strand guide from the warm strand and converts it into a subsequent one Directional driver unit bends, and the support roller as a reaction roller in the arch part the system is arranged between the hot strand and the cold strand.
  • Such thin slab continuous casting plants are well known, in particular So-called CSP (Compact Strip Production) casting machines with which band-shaped steel strands are produced, for example, a thickness of Have 20 to 65 mm and a width of about 500 to 1500 mm.
  • CSP Cosmetic Strip Production
  • the quality a cast strand can be further improved if this is immediate after exiting the continuous casting mold, i.e. in an area with still liquid core, is subjected to a reduction in thickness (cf. for example DE 41 35 214 A1).
  • a casting machine or continuous caster different strand formats are to be cast, that sets different mold exit dimensions ahead. That means that to start a continuous casting machine requires different cold strands Need start-up head.
  • start-up head has a lost at its upper end, detachably connected to the subsequent cold strand head.
  • the melt introduced into the continuous mold can solidify and the beginning of the cast strand.
  • the start head is on the actual cold strand attached, which is driven by drive rollers in the strand guide frame.
  • the invention is therefore based on the object for a continuous casting machine to simplify the changeover to a new strand format.
  • this object is achieved by the support roller in its bale with a strand format adapted to the thickest casting to be cast, in situ the Compensation area of the cold strand head opposite turn or - is provided.
  • This can be achieved that the support roller at one Format changes can remain unchanged in their installed position, so that there are no activities in the area, which is still hot for a long time after the end of the pouring the continuous caster need to be carried out. Because the remaining, i.e. not excluded bale area of the support roller takes over at everyone thickness format to be cast, e.g.
  • the ratio of the individual contact areas to each other can be so optimize that the Hertzian pressure to none of the critical operating conditions when conveying the cold strand with the cold strand head and pressing the lost cold strand head is exceeded.
  • a preferred embodiment of the invention provides that the compensation area with the same distance on both sides to the outside of the cold strand head in it is formed based on the total width of the middle part and the support roller has a corresponding central recess. This favors that they are not turned out bale surfaces of the support roller the warm strand to the edge areas also fit securely and guide it when the Warm strand due to the bending in the arch part of the system on its rear, supported side should bulge slightly in the edge areas, i.e. takes on a slightly concave contour across its width.
  • An alternative embodiment of the invention provides that the support roller two in Has spaced turns, each one Complementary compensation area of the cold strand head is assigned. In this case, there is central guidance and support of the hot strand, for example is sufficient if the bending radius is sufficiently large and it is too negligible pronounced bulges of the warm strand comes.
  • the compensation area of the cold strand head with a not beveled, corresponding to the respective strand thickness to be cast straight section at the end of the cold strand head facing the lost head is trained.
  • this is still the change of format an equalization of the difference in thickness between the one to be cast
  • Given the format of the lost head and the cold strand, on the other hand will also be a temporary guide of the trailing end of the cold strand head guaranteed over this straight section.
  • a well-known continuous casting plant 1 for manufacturing of thin slabs 2 in Fig. 1 are the oscillating continuous mold 3 and the subsequent strand guide 4 only partially shown.
  • the strand guide 4 5 drive rollers 6, a bending roller 7 and in the curved part follow in the strand extraction direction the system a support or reaction roller 8 and at the end of the sheet part a directional driver unit 9, also only partially shown
  • Continuous caster 1 is a rigid cold strand 10 vertically from below in the Continuous mold 3 introduced, as shown in the upper part of FIG. 1.
  • Cold strand 10 is equipped with a start-up head 12 according to FIG a releasably connected to the cold strand 10 cold strand head 13 and one of these decouplable lost head 14, which is at the start of casting engages self-sealing in the continuous mold 3.
  • the cold strand head 13 is on its side facing the support roller 8 (see FIGS. 1 and 3) in the middle a compensation area running downwards in a wedge shape over a limited length Mistake.
  • At its upper end facing the lost head 14 towards the compensation area 15 has a not beveled, the respective to straight section 16 corresponding to the casting strand thickness.
  • the support roller 8 is provided according to FIG. 4 with a recess or recess 17, which is dimensioned so that it the compensation area 15 of the cold strand head 13 can take up without contact in this area with the cold strand head 13 or the compensation area 15.
  • the depth of the recess 17 is such that they are the thickest to be cast within the assumed range Strand format is adapted. It still has to be when changing the format the cold strand head 13 are changed, the support roller 8 needs in position but no longer to be changed or adjusted. Because independent the thickness of the hot strand to be cast is guaranteed in any case, that the lying next to the rotation 17 bale areas of the support roller on the one side of the cold strand 10 or cold strand head 13 and on the other side support the warm strand 11. The lying next to the recess 17, supporting bale lengths of the support roller 8 are larger, the wider the warm strand Is 11; 4 shows a hot strand 11 with the smallest slab width.
  • the embodiment of the support roller 8 and the cold strand shown in FIG. 5 or Cold strand head 13 differs from that of FIG. 4 only in that the support roller 8 two at a distance, i.e. spaced turns 18 or 19 and the cold strand head the complementary compensation areas 20 or 21 not in the middle, but on both sides in the edge areas of the Has cold strand head 13. In this case it takes over between the turns 18, 19 lying, unchanged ball area of the support roller 8 the support of the cold strand 10 or cold strand head 13 and that not shown here Warm strand, which continues with sufficient width also on the bale areas can support next to the recesses 18, 19.
