Definitions

  • the invention relates to a strand guide, in particular for a slab caster for steel, with support segments in which frames are arranged, which have opposite rows of guide and drive rollers and the are held against each other via anchors.
  • EP 0 222 732 B1 discloses a strand guide with a plurality of rollers load-bearing support segments.
  • the support segments are in one piece Side member, in particular an arcuate side member attached.
  • Support straps and fitting bolts are provided, which are manufactured and arranged in a manner be that this roll misalignment is also avoided during installation and removal.
  • the Roller segments themselves are permanently installed as a closed unit.
  • EP 0 117 404 B1 also includes a support guide in a continuous casting plant for steel two opposite rows of guide and drive rollers are known which are stored in sections on trusses.
  • the head traverse is on supports a fixed crossbar arranged on a base frame is held by tie rods.
  • Another guide for the fixed crossbar (subframe) or the head crossbar (Top frame) is not provided.
  • the invention has set itself the goal, the above. Avoid disadvantages and a Strand guidance, especially for a slab caster for steel create a self-centering without play with a simple construction at least one of the opposing frames of the individual support segments to the strand.
  • links are provided which are conical to one another under one Opening angles are arranged, and the ends via holding elements at the end a frame and the other end are attached to at least one fixed point.
  • the handlebars are attached to the upper frame while the other end on the arc-shaped longitudinal member of the continuous caster or preferably be attached to the subframe.
  • the opening angle of the two Handlebars can be up to 60 °.
  • the conical opening is preferably in Strand guidance direction arranged.
  • console-shaped on the upper frame Extensions are planned.
  • connection between the handlebar and bracket on the frame are as joints or as non-rotatable brackets.
  • bracket handlebars which consist of a train and compressive forces and a lateral deformation-bearing material are built up.
  • bundles of rod-shaped or strip-shaped material is used, which has a square, polygonal or also have a round cross-section.
  • fretting corrosion between intermediate layers are provided for the individual handlebar elements.
  • the configuration according to the invention also facilitates the implementation of the dynamic width adjustment during the casting operation. This is This is particularly advantageous for soft reduction.
  • Handlebars Through the use of Handlebars is the freedom of movement of a continuous caster Upper frame to the lower frame, especially with regard to the degrees of freedom of the Tilting around the horizontal axes, significantly increased.
  • the schematic Figure 1 shows two frames arranged in parallel, one Upper frame 11 and a lower frame 12, which are spaced apart by anchors 31 to 34 are interconnected. At the end 13 of the frame 11 are at the same distance from the central axis (l) a Handlebar 41, 42 attached. The links 41, 42 are arranged conically to one another and are merged at breakpoint 45.
  • the frame 11 moves in a plane at a distance of the length of the anchor fixed frame 12.
  • the frame 11 is in the direction of its longitudinal extent as well as in its assignment to the central axis l by the links 41, 42.
  • FIG. 2 shows a support segment of a continuous casting installation with one Continuous sheet caster an upper frame 11 and a lower frame 12.
  • the Frames 11 and 12 are connected to one another via anchors 31 to 34, each one Have hydraulic device 35 to 38.
  • the upper frame 11 has console-shaped ends on both sides 13 Extensions 15. On the extension 15 pins 46 are provided, which in the right side of the sketch a hinge 48 and on the left side a holding element 43 as Have connection to the links 41, 42.
  • the links 41, 42 are connected at the other end via a holding element 44 or a joint 49 Pin 47 attached to the frame 12.
  • FIG. 3 shows the top view of the rollers 21 of the upper frame 11 (dashed lines shown) with the strand S carried out underneath
  • the links 41, 42 arranged on both sides of the support segment point head-end, the holding elements 43, 44 or the joints 48, 49.
  • FIG. 4 shows a handlebar 41 which is designed as a bar 51.
  • the single ones Strips are arranged so that at least one narrow side 52 of the strand is inclined and the broad sides 53 are connected to one another via intermediate layers 56 are.
  • a holding head 54 is non-positively attached to the handlebar 41.
  • the holding head 54 has an opening 55 which with one of the pins 46, 47 (see Figure 2) of the top and Subframe corresponds.
  • Rods 57 or round rods 58 are also shown schematically Rods 57 or round rods 58.
