Definitions

  • the invention relates to a continuous casting plant, in particular a stick ⁇ or bloom caster, approximately device with an insertable into a frame-like lifting table mold, and subsequent to the casting mold Strangu ⁇ , guide segments the Strang ⁇ transmitted from a plurality of strand guide rollers is formed and supported with the lifting table and moving Koki 1 lenoszi 11 egg device.
  • a continuous caster of this type is already known from DE-A 19 57 689, in which the mold, the lifting table carrying the mold, the mold 1 lenoszi 11 device and a first strand guide segment are arranged within a detachable spatial frame. This frame with all of its internals can be lifted off and replaced. At the same time, the next strand guide segment arranged below is also accessible and also interchangeable.
  • the mold with the lifting table and the first strand guide segment are arranged separately from one another in the spatial frame. This arrangement does not automatically adjust these components to one another. Just the alignment of the plane formed by the shaping inner wall of the mold and that of the rollers of the first strand guide segment Generable generators (strand surface) is particularly important because of the thin strand shell and requires a precise and complex adjustment.
  • a first strand guide segment preferably in the form of a castor frame
  • a downstream second strand guide segment preferably in the form of a bending zone
  • a mold stirrer is supported on the second strand guide segment.
  • a particular advantage of this arrangement is that an adjustment in the workshop is only necessary for the first and second strand guide segments forming a structural unit.
  • a particularly expedient embodiment results from the fact that the second strand guide segment carries raised supports in the area of the mold, which supports support for the mold or the lifting table carrying the mold and connecting elements, preferably hooks or eyes, for the common removal of mold, mold stirrer and have second strand guide segment.
  • a casting level measuring device consisting of a radiator element, preferably cobalt radiator, and a scintillation counter is arranged on the mold stirrer or on the supports of the second strand guide segment.
  • This arrangement makes it possible to arrange the non-co-oscillating casting level measuring device very close to the cavity and thus to keep the cobalt emitter as small as possible and at the same time to obtain a stable and clearly defined position for the casting level measuring device.
  • a particularly stable and offset-free continuous casting plant can be achieved in that the mold oscillating device is designed as a four-eccentric oscillator with a spring band guide.
  • FIG. 1 shows a schematic longitudinal section through the continuous casting plant in the area of the mold and the subsequent strand guiding device.
  • Fig. 2 illustrates the same embodiment with a modified cut.
  • the continuous caster is supported on a stationary plant structure 1.
  • the mold oscillation device 3 which is formed by a four-eccentric oscillator 4 and a spring band guide 5, is fixed on a support frame 2 of the plant supporting structure 1.
  • the mold oscillation device 3 is shown and described in detail in AT-PS 384 970. It consists essentially of four eccentrics arranged in the corner regions of the support frame 2, which are driven by a common rotary drive, whereby the rotary movement thus generated is converted into a vertical oscillating movement by short connecting rods.
  • the connecting rods of the mold oscillating device 3 are connected to a frame-shaped lifting table 6, which picks up the oscillating movement and transmits it to the mold 8. As can be seen from FIG.
  • a spring band guide 5 is arranged between the lifting table 6 and the support frame 2, which is essentially formed from a plurality of spring bands 7 or comparable elastic elements which are clamped in place with their ends on the support frame 2 and in their center leg ⁇ richly connected to the lifting table 6. This provides an exact positioning of the oscillating system parts with respect to the fixed system components, in particular the alignment of the oscillating mold 9 to the downstream strand guide device 9 mounted on the system structure 1.
  • the mold 8 consists of the mold element 10 and a portal-like mold frame 11, in which the mold element 10 is inserted.
  • the mold element 10 has a mold cavity corresponding to the format of the strand to be cast, which is formed by a copper tube or from copper plates, and a back-up construction with the corresponding devices for mold cooling.
  • the strand guiding device 9 is connected to the mold 8 in the strand conveying direction by a first strand guide segment 12 and a second strand guide segment 13.
  • the first strand guide segment 12 is constructed as a frame construction in which a plurality of rows of strand guide rollers 14 forming a closed cage are rotatably supported and is detachably fixed in the second strand guide segment 13 as a structural unit.
  • the second strand guide segment 13 is designed as a two-part frame, the outer arch frame 15 and the inner arch frame 16 being equipped with strand guide rollers 14 and the inner arch frame 16 being braced to the outer arch frame 15.
  • the second strand guide segment 13 is supported on the structure 1 via the outer arch frame 15 with the fixed bearing 17 and the floating bearing 18.
  • the outer arch frame 15 with its strand guide rollers 14 also provides the Reference page for setting the continuous caster.
  • the second strand guide segment 13 has a support surface 19 on which the mold stirrer 20 rests and is positioned in its position at a distance from the mold element 10.
  • the second strand guide segment 13 carries in the area of the mold 8 raised connecting piece 21 with supports 22 which come into engagement with the mold 8 or the mold frame 1 when the second strand guide segment 13 is removed and the simple removal and installation of what is referred to as the format-related maschmenblock enable a common component made of mold 8, mold stirrer 20, first strand guide segment 12 and second strand guide segment 13 with a short changeover time.
  • the supports 22 can be brought into engagement with the lifting table 6 when installing or removing the machine block.
  • the raised connecting piece 21 is provided with connecting elements 27, which are designed as hooks or eyelets, to which a lifting device can be articulated for installation and removal.
  • a non- ⁇ toszi ies G govantmeßem ⁇ chtung 24 consisting of a radiator element 25 and a scintillation counter 26 is arranged on the mold stirrer 20 in the area of the mold level 23.
  • the radiator element 25 and the scintillation counter 26 can be attached to the raised neck 21.
  • centering of the mold cavity of the mold 8 to the Strangschreibungsrol len 14 of the downstream strand guide segments 12, 13 can be carried out in a simple manner with a measuring sword.
  • the pre-set format-related machine head can be set up and fastened on the lift table 6 without further work.
  • the coolant circuit for the mold takes place via supply and discharge lines, not shown, which are guided through the mold frame 1 and the lift table 6 and which are automatically closed when the mold 8 is placed on the lift table 6.
