Definitions

  • the present invention relates to a roller carrier for supporting at least three strand guide rollers in a strand guide segment of a continuous casting machine for casting a strand with slab or thin slab cross section made of steel.
  • the object of the invention is to increase the ease of maintenance of a strand guide segment by a rigid and space-saving design of the roller carrier; Concretely, it should be possible to disassemble or assemble individual spray nozzles and spray water pipes even with a compact strand guide segment and without lengthy assembly work.
  • This construction is extremely stiff not only because of the closed frame construction but due to the fact that at least one inner longitudinal web or on at least one inner side rail at least one bearing block is arranged, particularly space-saving.
  • the frame forms a lattice-shaped structure with the at least one longitudinal member and / or the at least one longitudinal web a plurality of lattice windows, wherein a plurality, preferably each, lattice window is associated with at least one spray nozzle.
  • This makes it possible in a simple manner to dismantle a spray nozzle and an associated spray water pipe or to mount again. Since there is sufficient space in a lattice window by the construction according to the invention, also the cooling capacity of the secondary cooling can be increased.
  • the spray nozzle is designed as a single-substance nozzle for a cooling medium, for example for water, or as a multi-substance nozzle for a plurality of cooling media, for example water and air.
  • a carrier which extends substantially over the entire longitudinal or transverse extent of a roller carrier;
  • a longitudinal or transverse web is understood to mean a carrier which does not extend over the entire longitudinal or transverse extent of a roller carrier.
  • At least one transverse web which is arranged within the closed frame, together with the frame and the longitudinal member and / or the longitudinal web a lattice-shaped structure with a plurality of lattice windows, wherein a plurality of lattice windows is associated with at least one spray nozzle for cooling the strand ,
  • the rigidity of the roller carrier is further increased by the combination of longitudinal members or longitudinal webs with at least one cross member or crosspiece.
  • a plurality of consecutive, i. arranged one behind the other, longitudinal webs from a side member i. arranged one behind the other, longitudinal webs from a side member.
  • a plurality of successive, ie successively arranged, transverse webs form a cross member.
  • the production costs are reduced due to the smaller number of individual parts with the same rigidity of the roller carrier; However, it is insignificant for the functionality, whether a carrier is designed as a single part or formed of several subsequent webs.
  • an inner frame or an outer frame of a horizontal or vertical continuous casting machine comprises at least one roller carrier.
  • an inner bow frame or an outer bow frame of a sheet continuous casting machine comprises at least one roller carrier.
  • the beneficial effects of the invention are independent of the design of a continuous casting machine, i. a horizontal, vertical, or arc continuous casting machine.
  • At least two spray nozzles are associated with a lattice window, wherein a first spray nozzle is supported on a first transverse web or a first crossmember and a second spray nozzle is supported on a second transverse web or a second crossmember.
  • a first spray nozzle is supported on a first longitudinal web or a first longitudinal beam and a second spray nozzle is supported on a second longitudinal web or a second longitudinal beam.
  • a largely free positioning of the spray nozzles is given in the lattice window, so that the coolant distribution on the surface of the strand is more precisely adjustable.
  • a central strand guide roller is supported on at least one longitudinal member and on the frame, and supports two, in each case the middle strand guide roller upstream and downstream, strand guide rollers on the frame.
  • the upstream and downstream strand guide rollers also rely on either at least one transverse web or on at least one cross member.
  • the roller carrier is designed to be displaceable relative to the strand guide segment by means of at least one displacement device, it being possible for the displacement device to be designed as a pressure medium cylinder, in particular a hydraulic cylinder.
  • FIG. 1 is a strand guide segment 1 a sheet continuous casting with a roller carrier 2 according to the prior Technology (see eg the Fig. 1 of the DE10203240A1 ) shown in a sectional view.
  • liquid steel is poured into a mold, not shown, wherein the steel is cooled and forms an at least partially solidified strand in the mold.
  • the strand is pulled out of the mold and in a mold support downstream of the mold, which comprises a plurality of strand guide segments 1, supported, guided and further cooled.
  • the strand which is formed as a slab 6, is supported via a plurality of strand guide rollers 8 on a respective roller carrier 2.
  • Each roller carrier 2 has a closed frame 7 with a rectangular shape, which is formed of three arranged transversely to the casting direction 5 cross beams 13 and six arranged in the casting direction 5 longitudinal webs 16, wherein the frame 7 by means of the cross member 13 and the longitudinal webs 16 a plurality of lattice window 17th trains (cf. Fig. 2 ).
  • the three cross members 13 of a roller carrier 2 are associated with a plurality of bearing blocks 12, wherein each strand guide roller 8 is supported by at least two bearing blocks 12 on a roller carrier 2.
  • a spray nozzle 9 and a spray nozzle associated with the spray nozzle 10 (also referred to as nozzle shaft) is arranged between two cross members 13, wherein the slab 6 is cooled by the spray water 11. Since the continuous casting machine has a high casting speed, in particular in the production of thin slabs, the short roll spacings between two strand guide rollers 8 following in the casting direction result in particularly cramped space conditions in the area of the high cooling water output of the secondary cooling system Roller carrier 2 of the strand guide segment 1, so that in particular the assembly or disassembly of individual spray nozzles 9 and spray water pipes 10 is not possible without prolonged installation work.
  • FIGS. 2a and 2b are two views, a perspective view in Fig. 2a and an outline in Fig. 2b of two prior art roll carriers 2 for an inner bow frame of a strand guide segment.
  • Each roller carrier 2 forms over three cross member 13 in combination with six longitudinal webs a closed frame (highlighted at the top roller carrier by a dash-dotted line) and a plurality of lattice windows 17.
  • an inventive strand guide segment 1 is shown with two roller carriers 2 on the inner sheet frame 3 in a sectional view.
  • two strand guide rollers 8 are supported by each roller carrier 2, wherein each strand guide roller 8 is supported by four bearing blocks 12 on the roller carrier 2 (see. Fig. 4 ).
  • the roller carrier 2 itself has a closed frame 7, which is formed by two cross members 13 and two longitudinal members 15.
  • a - seen in casting 5 - arranged outside longitudinal member 15 are assigned three bearing blocks 12, each bearing block 12 a strand guide roller 8 is supported; a - seen in the casting direction 5 - inside arranged longitudinal web 16 is a bearing block 12 assigned.
  • the cross member 13, the longitudinal webs 16 and the side members 15 form three lattice windows 17, wherein a lattice window is formed for receiving at least two spray nozzles, not shown, for cooling a strand, not shown.
  • FIGS. 4a and 4b are two views, a perspective view in Fig. 4a and an outline in 4b of two roll carriers 2 according to the invention for an inner bow frame of a strand guiding segment.
  • Each roller carrier 2 forms a closed frame 7 via two transverse beams 13 in combination with two outer longitudinal beams 15.
  • the two outer longitudinal members 15 have three bearing blocks 12; the two - arranged within the closed frame 7 - longitudinal webs 16 each have a bearing block 12.
  • the longitudinal members 15 are offset from the ends of the cross member 13 inwardly; but depending on the specific requirements of the roller carrier, it is also possible to put the longitudinal members 15 at the end of the cross member 13. It would also be possible between the two outer longitudinal members 15 or between the two inner longitudinal webs 16 to arrange one or more cross member or a transverse web, whereby the rigidity of the roller carrier would be increased again.
  • FIG. 5 It is shown how two roller carriers 2 according to the invention have been connected by means of two - in the casting direction 5 - arranged outside side boxes 18 to an inner sheet frame 3, whereby the inner arc frame is formed by means acting on the corners, not shown, hydraulic cylinder displaceable relative to a stationary frame of the strand guide segment , Another, centrally (ie between the two roller carriers 2) arranged and also not shown hydraulic cylinder is used for hiring a single central roller, which is preferably designed to be driven.
