Definitions

  • the invention relates to a cooling arrangement for the rolling mill of a Continuous casting plant for heavy carriers with spray nozzles, which through lateral in the longitudinal direction of the rolling mill laid supply lines can be acted upon with a cooling liquid and compressed air.
  • FIG. 3 shows such an arrangement.
  • Such piping and nozzle arrangements for supply the secondary cooling system of the continuous casting plant see for an embodiment with two nozzles per side at least three pipelines before.
  • a line provides, such as the line L compressed air, the passed through a tee on both spray nozzles S and the two other lines W supply the cooling liquid in the form of water one each of the spray nozzles.
  • These three lines L and W run parallel to the cast strand S, here in the shape of a double-T beam is to be brought within the rolling stand in which different Rolls R1, R2 and R3 for the shaping of the strand S care.
  • the Spray nozzles D are each arranged so that they are in the gaps between spray adjacent rolls R1 while keeping as much as possible Touch the side surface of the strand S with its spray jet.
  • 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 based on the object, a Cooling arrangement of the type mentioned in such a way that you Construction is simpler and more reliable and that also the Montageund Installation costs can be kept as low as possible.
  • This embodiment requires only two pipes to supply the Secondary cooling system with air and water. Needless are further difficult and expensive to produce bent stub lines or Verteil Kunststoffe. It is sufficient to flanging a connection plate to the two supply pipes, which have corresponding connection points, these connection plates then in turn already the corresponding wear aligned or arranged spray nozzles. The assembly or disassembly is much easier.
  • connection points can the supply lines may be formed as a flange to which the connection plates can be attached in a simple manner. It is also advantageous the two supply lines with a small distance to each other relocate, allowing them in a simple way with a common connection flange be provided for fastening the connection plates can.
  • connection flanges on both sides of the supply lines be provided and each with a connection thread for To provide bolt for flanging the connection plates.
  • connection plate can be fixed be connected with two spacer tubes, one of which with the Compressed air and the other with the coolant line in conjunction stands, wherein the spacer tubes terminate in a flange which firmly with a Nozzle housing is connectable, with two under a certain Angle to each other and to the axes of the spacer tubes standing Is provided with spray nozzles.
  • spray nozzles are in this case with a mixing chamber and with channels for compressed air and coolant flow connected.
  • the connection plate also has through openings to the spacer tubes, which are sealed to the connection flanges abut the supply pipes.
  • connection plate itself is provided with a mixing chamber inside which via connection channels with the compressed air and with the coolant connection is connected and has an outlet nozzle, the connected to a connecting piece to a spray nozzle.
  • This embodiment is the mixture of cooling liquid and Compressed air therefore made within the connection plate and the Spray mixture is then added to or assigned to several supplied with spray nozzles.
  • the connecting piece can be connected to the Spray nozzles opposite the laying level of the supply lines be executed bent. It can also be detachable at the outlet nozzle attached and provided with an anti-rotation device, which ensures that the connecting line pieces to the spray nozzles only in one be determined very specific position on the outlet nozzle can.
  • This embodiment therefore provides the orientation of the spray safely, without an operator in a complex manner would have to adjust this spray angle by kinking lines. It also makes it possible with an identical connector to realize both spray positions with a spray nozzle.
  • FIG. 1 shows that two supply pipes 1 and 2 each with square or even rectangular cross section with low Distance from each other in the longitudinal direction of the strand S and parallel to whose center plane 17 are laid, in the same way as based already explained in Fig. 3, in a rolling stand of a continuous casting plant is guided and shaped.
  • the two supply lines 1 and 2 from one for compressed air supply and the other for cooling fluid or water supply, are arranged by at certain intervals Tabs 3 on one side and through the tabs 3 respectively opposite connection flanges 4 connected to each other and in each case on the side of the connection flanges 4 with openings 1a or 2a provided, via the compressed air or water respectively into appropriate 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, consisting of two spacer tubes 7 and 8 and a further flange. 9 consists, in turn, with the help of screws 10 a nozzle housing 11 is flanged.
  • This nozzle housing 11 is not shown in detail Way inside provided with a mixing chamber in the Compressed air and coolant from the spacer tubes 7 and 8 penetrates and mixed.
  • the coolant / compressed air mixture will then be the two Spray nozzles 12 and 13 which are at an angle ⁇ to each other Aligned previously on the shape of the strand S together is tuned with the spray pattern of the spray jet 14.
  • Tuned to the cooling system and the mill stand is also each the length of the spacer tubes 7 and 8.
  • the spacer tube unit 6 is attached to the flange 4 in a simple manner and by means of a bolt 15 can be fixed by the flanges 4 and 5, through the gap between the supply pipes 1 and 2 and passed through the tab 3 therethrough. It is possible a precise alignment of the spacer tube unit 6 and thus also the spray nozzles 12 and 13 to ensure by dowel pins 16, the one allow 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 parallel to each other and side by side and parallel to the median plane 17 of the strand S aligned. They are not here among each other, but arranged side by side in a horizontal installation level 25 and both on its top and on its underside with flanges 4 equipped, in turn, through their through holes the Establish connection to compressed air and coolant supply.
  • the connection plates 18 are each attached, via each a spray nozzle 19 is supplied with a bent Connecting line piece 20 is provided.
  • connection plate 18 Inside the connection plate 18 is here in a manner not shown in each case a mixing chamber provided, in which compressed air and coolant mix and then via a connecting piece 21 and the connecting pipe piece 20 to the spray nozzles 19 are performed. Also in this case are the spray jets 14 tuned to the shape of the strand S, which also for the Buckling angle of the connecting line piece 20 applies.
  • This connecting piece 20 is against rotation with the connecting piece 21 of Connection plate 18 connected and secured by a union nut, so that the connecting pipe piece 20 only in a very specific location can be attached to the connecting piece 21.
  • the spray nozzle 19 can therefore only in either the position shown above or in the one shown below Be aligned, both positions by a 180 ° Twist the connection plates 18 come about.
  • the connection plates 18 can also in this embodiment with a regulator 22 for controlling the compressed air / coolant ratio be provided.
  • This embodiment also allows easy and precise installation or disassembly in that the bolt 23, respectively the connection plate 18 holds on the flange 4, dissolved and the corresponding Spray nozzle unit removed, maintained and then re-set exactly becomes.
  • the non-rotating connection between connecting pipe piece 20 and connecting piece 21 and their backup via a union nut 24 is known per se and is therefore not explained in detail.
