Definitions

  • the invention relates to a device for continuous casting of liquid metals, in particular of liquid steel materials, with a strand guide for supporting and / or guiding and cooling the casting strand, consisting of successive in strand running groups of a fixed side and a lot side forming roller pairs and per roller group serving for pivotal mounting Segment frame, wherein a lot side frame by means of pairs of hydraulic piston-cylinder drives for basic adjustment and adjustment of the casting strand format thickness or the segment conicity in a casting break or continuous casting operation against the fixed side frame can be adjusted and wherein at least one segment frame with the pairs of rolls is interchangeable.
  • the invention is based on the object, without removing the hydraulic piston-cylinder drives and opening their connections to perform a change of roles segments the task.
  • the stated object is achieved according to the invention by arranging individual roller groups of fixed-side rollers and loose-side rollers on a straight or curved section of the strand guide in such a way that the piston-cylinder drives are mounted in a stationary support frame so that the fixed side frame and the loose side frame form a frame unit form on which the lot side frame or the loose side rollers are adjustable by means of the piston-cylinder drives at a distance from the fixed side rollers and that the frame unit solved in at least one side transverse guide from the support frame for removing the Lossrollen or Loss and after maintenance for installation again is connected to the stationary support frame or an additional, separate, stationary, spaced segment support frame and the piston-cylinder drives are each provided with a piston rod, which by means of a coupling to a piston rod extension is connected, wherein the end of the piston rod extension forms a guide block of the lot side in the fixed side frame.
  • the advantage is further that the separation of the fixed support frame (which carries the piston-cylinder drives) of the frame unit (with the fixed side and the Losseite) leads to a largely mechanical assembly and is therefore easier to handle.
  • the frame unit of fixed side frame and lot side frame is connected to the fixed support frame by means of adjustable clamping means.
  • adjustable clamping means As a result, the frictional connection via hydraulic or electrical clamping means can be controlled very accurately.
  • a further development is that the fixed side frame with the lot side frame by means of pairs of segment wheels arranged in both sides, running transversely to the strand running rails from the support frame away and after maintenance is moved back again.
  • the movement path can be defined such that segment stops are arranged on the fixed side frame for the travel path of the segment frame.
  • segment frame is guided on both sides in the direction of the axis of the piston-cylinder drives and the piston rod extension by means arranged on the axis of the piston rod extension guide blocks.
  • This design can be further developed to the effect that for the guide blocks each window in the framework of the continuous casting are provided, which guide the guide blocks vertically and release in the direction of the axis of a piston-cylinder drive for a Anstellweg the lot side frame to the fixed side frame.
  • Fig. 1 serves a strand guide 1 for supporting and / or guiding and cooling a cast in a continuous casting mold casting strand in strand running direction 2.
  • the strand guide 1 consists of roller groups 3, which are opposite to each other in pairs.
  • the distance between a pair of rollers 6 corresponds to a basic setting on the respective format thickness of the cast casting strand.
  • the spacing may be varied to accommodate cast strand format thickness or segment conicity in a pour break or continuous casting operation.
  • Several groups 3 of rollers form strand strand 1 in strand running direction 2, which is constructed on a framework of the continuous casting plant.
  • the roller groups 3 form a fixed side 4 on a fixed side frame 4a and are referred to below as fixed side rollers 4b.
  • the rear row of rollers form a loose side 5 in strand running direction 2, are rotatably mounted on a loose side frame 5a, and are hereinafter referred to as loose side rolls 5b.
  • each of the individual roller groups 3 are arranged.
  • piston-cylinder drives 8 are mounted on their cylinder housing 8a in a fixed support frame 9 so as to be stationary ( Fig. 1A ).
  • the piston rods 8b are in the operating state with the adjustable part, ie the lot side frame 5a in conjunction.
  • Fig. 1B how out Fig. 1B can be seen, the frame unit 11, consisting of the fixed side rollers 4b and the loose side rollers 5b on an at least lower transverse guide 10 after release of clamping means 16 of the stationary support frame 9 moved away and after maintenance for installation again ( Fig. 1A / 1B in the direction of the arrow to the left) are again connected to the stationary support frame 9.
  • the support frame 9 is fixed in the base frame (banana) of the continuous casting apparatus by means of a fixed bearing (top) and by means of a movable bearing (bottom).
  • the piston-cylinder drives 8 are each provided with a piston rod 8b, which is connectable or detachable by means of a coupling 13 to a piston rod extension 14, wherein the end 14a of the piston rod extension 14 has a guide block 15.
  • Fig. 2 / Fig. 2A is provided between the movable frame unit 11 and the stationary support frame 9 a fixed to the base frame (banana) of the strand guide 1 intermediate frame 18.
  • the intermediate frame 18 ( Fig. 2A ) is used to adapt the frame unit 11 over a defined distance 17, so that conversions of existing equipment can be made.
  • pairs of segment wheels 19 are provided which are guided in a pair of rails 20 extending on both sides of the segment frame 7.
  • the pair of rails 20 runs perpendicular to the strand running direction 2 and, if a crane is not to be used for the transport of the frame unit 11, are guided in the direction of a removal station, such as, for example, to the casting platform of the continuous casting plant.
  • the travel path of the segment frame 7 can be limited for operating settings by means of segment stops 12 ( Fig. 2 ).
  • the segment frame 7 is on both sides in the direction of the axis of the piston-cylinder drives 8 and the piston rod extension by means of the arranged on the axis of the piston rod extension 14 guide blocks 15 14 led.
  • windows 15a are respectively provided in the framework of the continuous casting apparatus, which guide the guide blocks 15 vertically and release them in the direction of the axis of a piston-cylinder drive 8 for a setting path of the lot side frame 5a to the fixed side frame 4a.
