Definitions

  • the invention relates to a device for a short start-up strand, which can be inserted from a receptacle approximately horizontally between driver rollers arranged in the arc shape of a sheet metal continuous casting installation, through an opening in the roller stand or in the cooling chamber.
  • Short approach strands are introduced in a metal continuous casting plant, in particular in steel continuous casting plants, which are built in an arc shape, either from the casting platform, lying on a trolley lying in the continuous casting mold from above (DE-AS 19 61 443) or, in order to pass the entire starting strand to avoid through the continuous casting mold, inserted through an opening of the cooling chamber or the roller stand between driven rollers of the support roller stand.
  • a start-up train device of the second type is known from DE-AS 15 08 758.
  • the present invention relates generally to a start-up train device of the second type.
  • the invention is therefore based on the object of being able to carry out maintenance work during the casting times on the start-up strand outside the hot zone and to be able to bring the start-up strand with the head side in the feed direction ready for entry.
  • the receptacle can be moved on a rail track running transversely to the casting direction and has an infeed level and a storage level, the infeed level and storage level being connected to one another by a transport means deflecting the start-up line and arranged at high altitudes. Due to the solution according to the invention, the maintenance can advantageously be carried out outside the hot area, and although the end side is pulled out in the direction of movement from the drive-direction unit, the start-up strand can be brought back into the feed-in path with the start-up head end.
  • the receptacle consists of horizontal frame parts and vertical frame parts, the infeed plane consisting of a horizontal frame part and the storage plane consisting of the horizontal frame part, each with pairs of rollers arranged, with a drive chain with carriers guided around chain wheels being provided between the roller pairs is.
  • Such a construction is very light and allows correspondingly economically dimensioned and operable drive elements.
  • the starting strand can be transported particularly advantageously into the support plane if a vertical guide rail is provided at the end of the receptacle opposite the feed side, in each case a lifting device above the storage plane and tangential to a chain wheel with chain on the frame part of the feed plane.
  • the paths for the storage level or for the infeed level are determined by assigning a switch which releases or closes the infeed level to the transport means deflecting the start-up line between the storage level and the infeed level.
  • the molten metal is poured into a continuous casting mold 2 after the relatively short start-up strand 3 has been inserted into the continuous casting mold 2 from below and a seal 4 has been inserted at the edge of the casting cross section.
  • the relatively short start-up line 3 is brought in from a receptacle 5, which is brought into position above the drive-straightening unit 6 and next to a cooling chamber 7.
  • the cooling chamber 7 has a flap 8 for the retraction process, and when the flap 8 is open, the start-up strand 3 is guided in advance via a guide 9 through an opening 10 into the effective area of driver rollers 11 and from there between support roller pairs 12a of the roller stand 12 pushed into the entrance area of the continuous casting mold 2.
  • the driver rollers 11 are then acted upon by the rotary drive 14 (only indicated) until the Starting strand 3 together with the cast strand attached to it (not visible) reaches the effective range of the drive-straightening unit 6.
  • the start-up strand 3 with its rear end 3a has passed the last pair of drive rollers 6a in the casting direction 15, it is transposed hanging on an eyelet 3b on a catch hook 16a of a lifting device 16 into the receptacle 5 (FIG. 2).
  • the receptacle 5 (FIGS. 2 to 6) can be moved on a rail track 17 running transversely to the casting direction 15 in the manner of a crane runway.
  • the receptacle 5 also has an infeed level 18 and an overlying storage level 19.
  • the further structure of the receptacle 5, which ensures short set-up times for the start-up line 3 and avoids a complex steel structure for storing longer start-up lines, is structured as follows:
  • the mount 5 is made up of firmly connected horizontal frame parts 20, 21 and 22 and vertical frame parts 23 , 24 and 25 are formed.
  • the horizontal frame part 22 has the infeed plane 18 and the horizontal frame part 21 has the storage level 19.
  • the storage level 19 carries pairs of rollers 26.
  • the infeed level 18 is formed by rollers 26a.
  • Supported on the infeed plane 18, but assigned to both planes by coordinating the diameter and the circumferential arrangement, sprockets 27 and 28 are rotatably supported at the ends of the receptacle 5.
  • a drive chain 29, to which at least one driver 30 is attached, runs over a pair of such chain wheels.
  • the chain 29 or the sprocket 27 is driven by means of the transmission 31 and a motor 33 connected via a clutch 32.
  • sprockets 27, 28 and separate gears 31 with motors 33 are provided in the directions of travel 34 of the receptacle 5 at a distance from a plurality of parallel casting lines (FIG. 3).
  • a lifting device 16 is also assigned to each casting wire.
  • the receptacle 5 can be moved by means of the pairs of wheels 35 and 36 and the travel drive 37 (FIGS. 3 and 4).
  • a projection 38 for the lifting device 16 is also formed on the frame part 20.
  • a vertical guide rail 40 is provided on the frame part 22 opposite the feed side 39, at the end 5a of the receptacle 5.
  • the transport means for the start-up line 3 deflects the start-up line 3 in the phase shown in FIG. 2 by means of the switch 41 into the support level 19, so that one end 3a of the start-up line 3 runs into the support level 19 with the eyelet 3b.
  • the switch 41 consists of the tongue 42 which is pivotally mounted about the axis 43 of a roller 26a. The starting strand 3 is pulled up to the position shown in FIG.
  • the switch 41 is changed over (FIG. 6), so that the motor 33 transports the chain 29 with the starting strand 3 into the feed plane 18.
  • the start-up strand 3 arrives with the start-up head 13 in the feed-in direction 44 into the guide 9 and into the opening 10 and thus between the driver rollers 11, as described at the beginning.
