Definitions
- the invention relates to a strand guide segment for guiding and cooling the Cast strand of a continuous caster, comprising one with traverses and guide rollers roller bridge formed between side walls, and a Coolant supply for the secondary cooling of the cast strand and the frame cooling, these having a coolant distribution and connectable to this Distribution pipes, spray pipes and spray nozzle at the end are provided.
- the cross members are mostly between the side walls of a strand guide element are designed as solid cross members, and the spray slats for strand cooling are from the back of the segment performed through the roller bridge.
- the document EP 0 642 857 A2 describes a continuous caster, the Strand guide segments with the variably adjustable width of the Strands arranged distributed, possibly in cooling zones in the strand running direction subdivided spray elements connected to cross-distributor pipes, especially battens are provided.
- the over the minimum strand width outer spray battens arranged further depend on the respective one String width can be switched on or off.
- the document US-PS 4,220,192 describes for installation in the area of the open Bottom of a vertically formed mold for continuous casting a combined System of guide rollers and spray cooling for the strand.
- the device has an elongated guideway that is flooded with water.
- the water drains through a number of sloping drains with terminal water spray nozzles, which are aligned so that they water above and below the rollers and against the surface of the cooling device spray.
- the document EP 0 028 686 B1 describes an adjustment device for along so-called extending the surface of a strand of a continuous caster Spray bars as a carrier for spray pipes directed onto the strand surface for a cooling medium.
- the Spray bars parallel at least in zones by means of a steering system self adjustable. All arranged on the four sides of the strand and Spray bars extending along the surface of the strand are of worn at least two steering levers, such that the spray bars at the change in distance in the direction of the longitudinal axis of the strand.
- the steering levers the lateral spray bars that are assigned to a strand surface, the center of which shifts with changing width of the strand surface are in Inclined swiveling.
- the sloping planes form perpendicular to each other to the assigned strand surface through the spray plane running through the spray tubes an acute angle, such that with the change in distance of the spray bar a transverse displacement of the spray bars including spray pipes relative to Along the longitudinal axis.
- Document DE 30 39 443 A1 describes a device for adjustment of nozzle pipes from the position for a narrow slab into a wider one Slab appropriate position by adjusting spindles, the base the spray fan by removing the spray nozzles from the strand surface is increased accordingly.
- Document DE 197 02 718 C1 discloses a method and an apparatus for cooling medium control in the cooling section of a continuous caster, in which to increase or reduce the amount of coolant on spray battens arranged nozzles of a cooling zone of the entire cooling section can be switched on and off are.
- spray battens become selective within a zone selected and combined into at least two spray groups and at Below a specified system pressure for the cooling medium are the individual groups alternately in and out at a fixed time interval switched on.
- the invention has for its object to provide an improved and, in particular, simplified design of a strand guide segment, comprising a roller bridge formed with cross members and guide rollers between side walls, and a coolant supply for the secondary cooling of the cast strand and the frame cooling, these also being a Classification of the cooling nozzles into the middle, first outside and second outside areas, and can be switched on and off, and are provided with a coolant distribution and connecting pipes, spray pipes and spray nozzles at the ends, and as a result of the elimination of the water distributors and nozzle sticks a very compact one Design is realized. Furthermore, relatively short injection units are to achieve a high positional accuracy of the nozzles, an additional frame cooling is to be dispensed with and good accessibility of the components after a breakthrough is to be achieved.
- the strand guide segment shown in FIG. 1 for guiding and Cooling the cast strand of a continuous caster includes one with trusses 1.1; 1.2; 1.3 roller bridge formed between side walls 51, 51 '.
- the Segment has a loose and fixed side as well as assignable roller bearings 52 and guide rollers 50.
- a coolant supply 115, 125, 135 for the Secondary cooling of the cast strand and the frame cooling are provided, wherein this usually from a water distribution and connectable to this Manifold pipes, spray pipes and spray nozzles 6 at the ends.
- the trusses 1.1; 1.2; 1.3 consist of rectangular hollow sections welded together, whereby this through internal communication means such as pipes or Holes several separable truss areas 1.10; 1.20; 1.30 form that can be switched on or off according to the current string width.
- Each truss 1.1; 1.2; 1.3 is top and bottom with water flow Welding blocks 2 are provided, in each of which an injection unit 7 is inserted is.
- An embodiment according to the invention provides that an injection unit 7 with a screw connection 3, an adjoining pipe section 4 with a screw sleeve 5 and a terminal spray nozzle 6 is.
- a configuration of the injection unit 7 can also be provided be made with a welding element 8 such as a pipe section 9 or molded part screw-on spray nozzle 6.
- a strand guide segment for guiding and cooling the cast strand a continuous caster is clear, compact and optimally for each line width by switching on and off corresponding Pressurized water feeds can be adapted to the current line width.
