Definitions

  • the invention relates to a device for adjusting the slab profile of a continuously cast slab, in particular a thin slab, the profile according to given requirements for its crowning and / or wedging through the gap geometry of strand guide rollers of a strand guiding system are determined, and these in individual strand guide segments in pairs opposite by adjusting means via tie rods at their outer end portions tense together, forming a hard page and a lot side Frame parts are stored.
  • the slab profile is essentially in the range of the roll gap geometry the Resterstarrung the strand dependent. Due to alignment error, roller wear, elastic deformations of the segment, due to temperature influence and different casting widths, as well as a different solidification profile over the casting length and width creates a roller gap geometry and thus a Casting profile, which meets the high demands of the rolling mill and thus of the final product partly not enough.
  • the document DE-197 45 056-A discloses a method of producing slabs in one Continuous casting plant, with one of the casting mold downstream, divided into segments Strand guide, each consisting of a two-part segment frame, whose frame parts are clamped together by means of hydraulic cylinders and in the pairs opposing roles for support and Promotion of solidifying cast strand are employed, with at least one These roles, the drive roller, for the transmission of the strand conveying forces with a defined setting against the casting is made, with the requirement, that the tension of the segment frame parts steplessly by positional and force-controlled Segmentanstellzylinder takes place, with which also for the transmission the stranding forces required applied adjusting force for the drive roller becomes.
  • a continuous casting plant suitable for carrying out the process for producing slabs contains four position- and force-controlled segment setting cylinders, the two segmental frame parts with distance - without spacers - with each other connect and clamp against each other.
  • the document DE 43 06 853 A1 describes a strand guide on continuous casting for the production of slabs, in particular after the casting-rolling process, with adjustable to different strand thicknesses, in pairs opposite Rollers attached to tie rods connected to frame or scaffolding parts stored the strand guide and its tie rods of piston-cylinder units are formed and in the power flow of the piston-cylinder units between upper and Lower frame parts spacers are inserted.
  • a hydraulic ring cylinder which surrounds the piston rod and the annular piston frictionally the spacer wearing.
  • the hydraulic ring cylinders are supported on side frames and the Page frames connect at least two subframes to a segment of the Strand guide.
  • the document EP 0 545 104 B1 discloses a method for continuous casting of Slabs or blocks in a continuous casting plant with soft-reduction route, the individually or as a segment by means of hydraulic cylinder against each other engageable and by means of spindles in their clear distance from each other continuously adjustable rollers having.
  • the contact force during casting is reduced and the spindles are reduced with reduced load to a desired Maulweitenwear. This will be suggested that the difference between cylinder force and ferrostatic load is measured continuously.
  • the apparatus for carrying out the method in a continuous casting plant with soft reduction section which can be used individually or as a Segment by means of hydraulic cylinder against each other adjustable and by means of spindles has steplessly adjustable rollers in their clear distance, are the spindles supported on continuously measuring pressure sockets and connected to an adjusting drive.
  • the object of the invention is a new strand guiding concept to propose, in addition to cost advantages, the possibility of targeted influencing of crowning and wedging of a slab profile, in particular a thin slab profile.
  • Embodiments of the device are provided according to the subclaims.
  • FIG. 1 shows parts of a strand guiding device with the continuous thin slab 1 through the successive guide segments 3, 4 and 5, of which only the guide segment 4 is shown completely. It's on Support frame 12 is arranged and has in pairs opposite to by Adjustment means 16 tensioned together by tie rods 8 at their outer end regions, a fixed side 7 and a loose side 6 forming frame parts 10, 9th
  • the central region of the frame part 10 is a force means 11 assigned and trained for applying both tensile and compressive forces.
  • the power means 11 is a hydraulically or pneumatically actuated plunger cylinder. This is regulated in both directions zug- or pressure-actuated. He engages the fixed side of the frame part 10 and is firmly anchored in the support frame 12. This power means 11 may also be an electric motor drivable Stellspindeltrieb be.
  • Fig. 1 shows that individual guide segments 3 to 5 of a them are added to the strand guide system connecting support frame 12.
  • the Frame parts 6, 7 are with a comparatively high moment of resistance against Bend formed, however, under the action of the force of the force 11 in Limits elastically deformable.
  • the frame part 10 of the fixed side 7 each end on fixed stops 13, 14 of the support frame 12 can be supported and targeted by means of force of the power means elastically deformable, eg. in the sense that is deformed by pulling the frame member 10 concave.
  • the deformation in the central region an amount of one to several mm or a fraction of a mm, whereby a small but required crowning of the extruded profile is achieved.
  • the piston rod 15 of the power means 11 is articulated in the frame part 10 of the fixed side 7 anchored.
  • FIG. 1 shows that the guide segment can be moved on a running rail 17 fixedly connected to the support frame for the purpose of replacement.
  • This measure allows for the purposes of the invention, a rapid interchangeability of individual guide segments 3 to 5, whereby a change in the thin slab profile can be considered for program change in the continuous casting program with relatively low cost.
  • the adjusting means 16 of the tie rods 8 may be hydraulically or electromechanically energizable force means.
