Definitions

  • the invention relates to a cooling arrangement for the secondary cooling of a continuous casting plant for heavy carriers with spray nozzles, which are acted upon by lateral parallel to the casting strand supply lines with a cooling liquid and compressed air, each one each side of the plant associated cooling liquid and compressed air line are provided, which laid parallel to each other and are provided with connection flanges for attachment of connection plates, which are fixedly connected to the spray nozzles, wherein each connection flange is connected in each case to a connection plate which is provided internally with a mixing chamber, communicates via connecting channels with the supply lines and has an outlet connection, which is connected to a connecting piece to a spray nozzle.
  • FIG. 3 shows such an arrangement.
  • Such piping and nozzle arrangements for supply of the secondary cooling system of the continuous casting plant provide for a design with two nozzles per side at least three pipes.
  • a line supplies such as the line L compressed air, which is passed through a tee on both spray nozzles S and the other two lines W supply the cooling liquid in the form of water to one of the spray nozzles.
  • These three lines L and W are parallel to the casting strand S, which is to be brought here in the form of a double-T-beam within the strand guide, in which various support rollers R1, R2 and R3 provide for the shaping of the strand S.
  • the spray nozzles D are each arranged so that they spray into the gaps between adjacent rollers R1 while touching as possible the entire side surface of the strand S with their spray.
  • the feed lines W and L run parallel to the cast strand S, they must be routed outside the respective segment frame.
  • the supply of compressed air and water via relatively thin lines L 1 which must be bent according to the injection direction.
  • at least three of the branch lines L 1 two of which are bent, necessary and an intermediate manifold, which is provided here for the compressed air supply, but also for the water supply may be provided when compressed air through the outside lines W is performed.
  • the present invention is therefore the object of a cooling arrangement of the type mentioned in such a way that it can be used variably, easy to use, installation and maintenance and by a modular design cost.
  • the connecting line piece is bent relative to the laying plane of the adjacent supply lines, that the connecting line piece is detachably attached to the connection piece of the connection plate and rotated by 180 ° and that the connection plates are provided with a regulating device for controlling a compressed air / coolant ratio.
  • This embodiment requires only two pipes to supply the secondary cooling system with air and water. Needless are also difficult and expensive to produce bent stub lines or distributors. It is sufficient flanging a connection plate to the two supply pipes having corresponding connection points, these connection plates then in turn already carry the appropriately aligned or arranged spray nozzles. The assembly or disassembly is much easier.
  • the mixture of cooling liquid and compressed air is made only in the mixing chamber within the connection plate and the spray mixture is then supplied to the associated or even to several associated spray nozzles.
  • the connecting line piece is detachably attached to the outlet nozzle and provided with a rotation, which ensures that the connecting line pieces can be attached to the spray nozzles only in a very specific position on the outlet nozzle.
  • This embodiment therefore ensures the alignment of the spray jet, without an operator would have to adjust this spraying angle by bending lines in a complex manner. It is thereby also possible to realize both spray positions with an identical connection piece with a spray nozzle.
  • connection plate can be firmly connected to two spacer tubes, one of which is in communication with the compressed air and the other with the coolant line, the spacer tubes terminate in a flange which is fixedly connected to a nozzle housing, with two under a certain angles to each other and to the axes of the spacer tubes standing spray nozzles is provided.
  • These spray nozzles are in this case with a mixing chamber and connected to ducts for compressed air and coolant ducting.
  • the terminal plate has through holes to the spacer tubes, which bear sealed against the connecting flanges of the supply pipes.
  • FIG. 1 shows that two supply pipes 1 and 2, each with a square or rectangular cross-section, are laid at a small distance from each other in the longitudinal direction of the strand S and parallel to its center plane 17, in the same way as with reference to FIG explained, is guided in a rolling stand of a continuous casting plant and molded.
  • the two supply lines 1 and 2, one of which for compressed air supply and the other todestattkeits or. Water supply is, are connected by spaced at certain intervals tabs 3 on the one side and by the tabs 3 each opposite connection flanges 4 and each provided on the side of the connection flanges 4 with openings 1a and 2a, via the compressed air or water respectively into corresponding Through openings of the flanges can occur.
  • each flange 4 Attached to each flange 4 is in each case a connection plate in the form of a flange 5 of a spacer tube unit 6, which consists of two spacer tubes 7 and 8 and a further flange 9, to which in turn by means of screws 10, a nozzle housing 11 is flanged.
  • This nozzle housing 11 is provided in a manner not shown in the interior with a mixing chamber in the Compressed air and coolant from the spacer tubes 7 and 8 penetrates and is mixed.
  • the coolant / compressed air mixture is then supplied to the two spray nozzles 12 and 13, which are aligned at an angle ⁇ to each other, which is previously tuned to the shape of the strand S together with the spray pattern of the spray jet 14.
  • Tuned to the cooling system and the rolling stand is also the length of the spacer tubes 7 and 8 respectively.
  • the spacer tube unit 6 can be easily attached to the flange 4 and secured by means of a bolt 15, by the flanges 4 and 5, through the gap between the supply pipes 1 and 2 and is passed through the tab 3 therethrough. It is possible to ensure a precise alignment of the spacer tube unit 6 and thus also the spray nozzles 12 and 13 by dowel pins 16, which allow an exact alignment of the flanges 4 and 5 to each other.
  • Fig. 2 shows a variant of a cooling arrangement according to the invention.
  • the two supply pipes 1 and 2 are aligned parallel to each other and side by side and parallel to the center plane 17 of the strand S. But they are not here among each other, but arranged side by side in a horizontal installation level 25 and equipped both on its top and on its underside with flanges 4, which in turn connect via their passage openings to the compressed air and coolant supply.
  • the connection plates 18 are attached, via each of which a spray nozzle 19 is supplied, which is provided with a bent connection line piece 20.
  • a mixing chamber is provided here in a manner not shown, in which compressed air and coolant are mixed and then passed through a connecting piece 21 and the connecting pipe piece 20 to the spray nozzles 19.
  • the spray jets 14 are matched to the shape of the strand S, which also applies to the bending angle of the connecting line piece 20.
  • This connecting line piece 20 is connected against rotation with the connecting piece 21 of the connection plate 18 and secured by a union nut, so that the connecting pipe piece 20 can be attached to the connecting piece 21 only in a very specific position.
  • the spray nozzle 19 can therefore be aligned only in either the position shown above or in the position shown below, both positions come about by a 180 ° rotation of the connection plates 18.
  • the connection plates 18 may also be provided in this embodiment with a regulator 22 for controlling the compressed air / coolant ratio.
  • This embodiment also permits easy and precise assembly or disassembly in that the threaded bolt 23, which respectively holds the connection plate 18 on the flange 4, is loosened and the corresponding spray nozzle unit removed, serviced, and then accurately set again becomes.
  • the torsion-proof connection between the connecting pipe piece 20 and connecting piece 21 and its securing via a union nut 24 is known per se and is therefore not explained in detail.
