Definitions

  • the invention relates to a continuous caster, in particular a billet or bloom caster, with one in a frame-shaped lifting table insertable mold and a strand guiding device connected to the mold, consisting of several strand guide segments carrying strand guide rollers is formed and with a supporting the lifting table and moving mold oscillating device.
  • a continuous caster of this type is already known from DE-A 19 57 689 known, in which the mold, the lifting table supporting the mold, the Mold oscillating device and a first strand guide segment within a detachable spatial frame is arranged. This frame is with everything its internals can be lifted off and replaced. At the same time, too the next strand guide segment arranged below is accessible and also interchangeable.
  • a continuous caster is known in which a mold and that castor frame attached to the mold on the output side, as well as a castor frame Subsequent bending zone by a support frame which grips the mold and the bending zone can be removed from the continuous caster.
  • This conception requires a multiple adjustment of the individual components to each other.
  • the wall of the Mold cavity for generating the subsequent casters, as well as these Casters to the strand guide rollers of the downstream bending zone with one appropriate ruler can be set.
  • the adjustment other components arranged in the mold area such as. B. the mold stirrer or Casting level measuring device could be installed.
  • the object of the invention is therefore to avoid the above disadvantages and from the known Components usually used in a continuous caster, mold, lifting table, Kokillenoszillier coupled, the downstream strand guide and any additional devices, such as mold stirrers and G foolspiegelmeß coupled to form a unit in the short change times by the Formation of a format-related machine block and a reduced maintenance effort is possible due to the modular structure of the machine components.
  • a first strand guide segment in one subordinate second strand guide segment is releasably integrated that a mold stirrer is supported on the second strand guide segment and that the second The strand guide segment in the area of the mold supports which supports Support for the mold or the lifting table supporting the mold and connecting elements for the joint expansion of the mold, mold stirrer and the second Have strand guide segment.
  • a particular advantage of this arrangement is that that only for the first and second strand guide segment forming a structural unit Adjustment in the workshop is necessary.
  • the first strand guide segment is as Castor frame and the second strand guide segment designed as a bending zone.
  • the Fasteners are formed by hooks or eyes.
  • a Casting level measuring device consisting of a radiator element and a Scintillation counter on the mold stirrer or on the supports of the second Strand guide segment is arranged.
  • A is preferred as the radiating element Cobalt heater used.
  • a particularly stable and offset-free continuous casting plant can be achieved in that the mold oscillation device as a four-eccentric oscillator with spring band guide is trained.
  • FIG. 1 shows a schematic longitudinal section through the continuous casting plant in the area of Mold and the subsequent strand guide device shows.
  • Fig. 2 illustrates the same embodiment with a modified cut.
  • the continuous casting plant is supported on a fixed plant structure 1.
  • the Kokillenoszillier listening 3 is fixed by a four eccentric oscillator 4 and a spring band guide 5 is formed.
  • the Mold oscillating device 3 is shown and described in detail in AT-PS 384 970. It consists essentially of four arranged in the corner regions of the support frame 2 Eccentrics, which are driven by a common rotary drive, whereby the rotation thus generated by short connecting rods in a vertical Oscillating movement is implemented.
  • the connecting rods of the mold oscillating device 3 are connected to a frame-shaped lifting table 6, which Picks up oscillating movement and transfers it to the mold 8. As from Fig.
  • the mold 8 consists of the mold element 10 and a portal-like one Mold frame 11, in which the mold element 10 is inserted.
  • the Mold element 10 has the format of the strand to be cast corresponding mold cavity on that of a copper tube or out Copper plates are formed and a back support structure with the appropriate equipment for mold cooling.
  • the hot strand closes the mold 8 in the strand conveying direction promoting and supporting strand guide device 9 with 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 several rows of strand guide rollers forming a closed cage 14 are rotatably mounted and is detachable as a structural unit in the second strand guide segment 13 fixed.
  • the second strand guide segment 13 is as two-part frame executed, the outer arch frame 15 and the Inner arch frame 16 is equipped with strand guide rollers 14 and Inner arch frame 16 is clamped to the outer arch frame 15.
  • the second Strand guide segment 13 is over the outer arch frame 15 with the Fixed bearing 17 and the floating bearing 18 supported on the system structure 1.
  • 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 bearing surface 19 which the mold stirrer 20 rests and in its position at a distance from Mold element 10 is positioned.
  • the second strand guide segment 13 carries 8 hoisted supports 21 with supports 22 in the area of the mold when expanding the second strand guide segment 13 with the mold 8 or the mold frame 11 engage and the simple out and Installation of the common, referred to as format-related machine block Component made of mold 8, mold stirrer 20, first strand guide segment 12 and enable the second strand guide segment 13 with a short changeover time.
  • the Pads 22 with the lifting table 6 when installing or removing the machine block in Intervention can be brought.
  • the raised supports 21 are also included Connecting elements 27, which are designed as hooks or eyes, provided on which a hoist can be linked for installation and removal.
  • a non-oscillating Casting level measuring device 24 consisting of a radiator element 25 and a scintillation counter 26 is arranged on the mold stirrer 20.
  • the radiator element 25 and Scintillation counter 26 to be attached to the raised supports 21.
  • the coolant circuit for the mold is carried out by means not shown and derivatives that are led through the mold frame 11 and the lifting table 6 and automatically when the mold 8 is placed on the lifting table 6 getting closed.
