Definitions

  • the invention relates to a device for changing a segment of a formed from several segments arc of a strand guide for a Continuous casting machine, on the liquid metals, in particular liquid steel, is cast, the segments individually releasably secured in segment carriers are and a dissolved segment in a guide by means of a chain, a first Traverse and a crane to the casting platform is liftable.
  • the segments are used in particular on slab continuous casting machines and must at intervals during repairs or / or Maintenance work to be expanded and spent in a remote workshop.
  • a segment changing device is described in DE 29 08 476.
  • the segments carry expansion rolls that reach into a radius of curvature stationary guides run, which are arranged radially to the arc profile.
  • For all guides is a movable, reaching up to the radius of curvature a horizontal axis pivoting, inner track section formed selectively can be adjusted to a stationary guide.
  • These are insertable Locking devices for the aligned positioning and support of the Rail section provided on the stationary guides.
  • the invention is based on the object, the accessibility to the segments such continuous casting machines, the weight of the segments, which can be up to 60 t and more, must be taken into account.
  • a segment carrier is held by trunnions in a U-shaped, second cross member whose lateral legs hang on one chain each. This can be done on both sides the continuous casting machine at different levels an improved ascent be achieved with free accessibility to the segments.
  • An advantage In addition, the carrying capacity of such a system is of the required order of magnitude with free arch interior and consequently improved accessibility to the segments on the outer and inner bow.
  • the accessibility is further improved by an inspection is arranged between the segments and the strand guide.
  • the formation of the device can also be such that at both End sides of the strand guide, each parallel, following the course of a guide, Removal chains are guided in each case in an upper rail and the removal chains at the crane end by means of the first crossbeam, the crane loops carries, are interconnected.
  • the high load can be transported in the rails easier by that the removal chains each by means of rotatably mounted in the chain links guide wheels are movable in the rails.
  • expansion chains on both sides with the second traverse for receiving a segment are connected by means of fastening bolts.
  • the angle supports forms and has the fastening latch, connected to the segment are.
  • Another embodiment provides that one of the angle brackets as a moment support on the opposite side of the support roller drive side and that the segment on that side is spaced apart by at least two Trunnion and a bolt and on the other side by means of a bolt can be hung.
  • the advantage is that the segment at the input and Removal can be performed in the direction of the rail track.
  • the double-backed Design takes into account, especially in the upper part of Continuous casting machine occurring during segment change large vertical Force components with segment weights up to 60 t.
  • Another improvement is that at the bottom chain link everyone Removal chain is provided a hinged threading Einfädelrolle. Thereby The chains from the casting platform are used to remove a segment Threaded easier by means of the crane in the guide rails.
  • Another embodiment is that on both sides of the strand guide free access areas with free accessibility to the segments are provided. This will provide maintenance and monitoring of plant components favored.
  • the walkways can have a minimum width of 500 mm, so even smaller loads are carried to the segments can.
  • Fig. 1 the continuous casting plant is seen from the side, so that the BogenVerlauf the strand guide in the form of a Slitzrollengerüstes 2 is visible, the segments 1 in the operating position are installed.
  • the guides 4 for the segment carrier 3 exist from paired rails 4a and extend from the casting platform 7 with a continuous casting mold 7a into the region of the end positions of the segments 1.
  • An upper rail 4a extends in an arc to the end position and a lower rail 4b to behind the end position.
  • the rails 4a, 4b together.
  • a solved one Segment 1 can in the guide 4 by means of a chain pair 5 and a crane 6 are raised to the casting platform 7.
  • FIG. 2 are at the two end faces 8a and 8b of the Strand guide 2, each parallel, adapted to the course of the strand guide 2, Removal chains 5a and 5b guided in each case a rail-like guide 4.
  • the individual chains 5a and 5b are at the crane end 9 by means of a first Traverse 10, which has at least one crane loop 11, connected together.
  • the removal chains 5a, 5b become stable and parallel by means of spacers 12 held.
  • Each individual chain 5a, 5b consists of chain links 13 (of Type 990 x 380), with a bolt 14 and guide wheels 15.
  • the guide wheels 15 run in the rails 4a.
  • the chain links 13 have side plates 16 on.
  • the chain links 13 of the removal chains 5a, 5b are each by means of the bolt 14 held together.
  • a second traverse 10a forms at a segment-side end 17 angle brackets 10b and 10c, wherein fastening bolt 18 a connection to produce the respective expansion chain 5a, 5b.
  • angle brackets 10b and 10c Within the angle brackets 10b and 10c are screws 19 and other bolts 20 provided in guide rails 21.
  • the segment 1 engages by means of trunnions 22 in this guide rails 21 a.
  • the left angle bracket 10b is also opposite as a moment support 23 to the support roller drive side 24 executed. Grab on page 25 in the moment support 23 two support pins 22 and on the support roller drive side 24 of the right angle bracket 10c, a single trunnion 22nd
  • the double-sided version on page 25 takes into account the particular occurring in the upper part of the continuous casting machine at the segment change large vertical force components used in segment weights of e.g. 60 t arise.
  • each disassembly chain 5a, 5b is one on an axis articulated threading roller 26 connected.
  • the crane 6 engages with the crane hook around a bolt 27, wherein this is mounted by means of axle holder 28.
  • the lower, second cross member 10a is connected by means of the fastening bolt 18 with the expansion chain 5a (5b).
  • the threading roller 26 is pivotable about the axis.
  • the guide wheel 15 can be seen within the chain link 13 rotatably mounted.
  • the removal chains 5a, 5b are each by means of the fastening pin 18 connected to the second cross member 10a, wherein a cover 29, a Lubrication 30 and a cylinder head screw 31 form the counter bearing.
  • the Guide wheel 15 is mounted on a shaft journal 32, which by means of bushes 33rd is guided.
  • the bearing is closed by means of a cover 34.
  • Fig. 5 shows the continuous casting in elevation with the casting platform 7. Due to the Position of the support roller frame 2 in the segments 1 and the mutual arrangement of single chains 5a and 5b on the side 25 and the support roller drive side 24, a plurality of free walk-up areas 38 with free Accessibility to the segments 1 created.
