Definitions

  • the invention relates to a continuous casting method according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 6.
  • the publication DE-A-101 43 419 refers to a method and a device for draining drainage water in the inner arc of a beam blank casting machine.
  • This drainage water is raised by means of a discharge device, which is equipped with jet nozzles, and passed over the lateral profile edges of the inner arc in a sintering trough.
  • a discharge device which is equipped with jet nozzles
  • the water is passed from the inner arc on the side of the strand in a sintering channel located underneath.
  • a disadvantage of this method is that a permanently high energy consumption for the generation of sufficient back pressure is necessary.
  • the present invention has for its object to provide an economically advantageous method of the type mentioned above and to provide an apparatus for performing the method with which the excessive cooling in the inner arc of Vorprofilstranges can be largely avoided.
  • the excessive cooling caused in the inner arc of the Vorprofilstranges caused by cooling down water can be largely avoided, with only water nozzles are used.
  • the additional cooling effect by the deflection water can be compensated by the reduction of the cooling water.
  • heated diverting water can be used.
  • the cooling of the pre-profile strand can be advantageously influenced by adjusting the deflection water temperature.
  • Fig.1 shows a continuous casting plant 1 with a water-cooled mold 2, from which the liquid metal, in particular steel, is continuously led away with shell formation as Giessstrang.
  • the casting strand is a pre-profile, in particular a double-T pre-profile 3, the cross section of Fig. 2 and 3 it can be seen, and a web 4 and two lateral flanges 5, 6 has.
  • the solidification of an outer, solid strand shell takes place already in the mold 2 (primary cooling).
  • the vertically emerging from the mold 2 Vorprofilstrang 3 is guided by an arcuate strand guide 10 and bent into the horizontal. Directed by a straightening unit 11 it passes to a flame cutting machine 12.
  • the strand guide 10 comprises a plurality of successively arranged strand guide segments or modules 10a, 10b (in Fig. 1 two are indicated), of which at least the first segment 10a adjoining the mold 2, together with guide rollers 15, spray nozzles 16 (FIG. Fig. 2 ) for supplying cooling water, by means of which a so-called secondary cooling of the Vorprofilstranges 3 takes place.
  • the two water nozzles 21, 22 are preferably connected to a common water connection 20.
  • they can advantageously be arranged to be movable back and forth transversely to the lateral flanges 5, 6.
  • the water nozzles with the deflection water are advantageously already used in the initial, substantially still vertical region of the arcuate strand guide 10 and arranged, for example, in the region between the two first strand guide segments 10a, 10b (with arrow A) in Fig. 1 indicated).
  • the preferably lying in a common plane water nozzles 21, 22 are then directed at a predetermined angle to the sheet tangent, which is between approximately 0 ° and 90 °.
  • the deflection water can also be introduced into the pre-profile strand 3 at an angle of approximately 45 ° to the arc tangent approximately in the middle region of the arcuate strand guide 10.
  • the water nozzles 21, 22 and the two water nozzles 21, 22 common plane could also enclose an angle between 0 ° and 90 °.
  • the two directed to the transition from the web 4 to the respective flange 5, 6 of the Vorprofilstranges 3 water nozzles 21, 22 lie in a common plane which encloses the arc tangent between approximately 0 ° and 90 ° amounting angle.
  • the excessive cooling in the inner arc of the pre-profiled strand caused by cooling down water can be largely avoided, only water nozzles being used. Neither additional baffles or funnels in the shoulder area, ie between the lateral flanges of the pre-profile, nor compressed air is required. This eliminates the associated installations and operating costs. The water used anyway in this area is available at low cost.
  • the deflection device is located outside the shoulder region, and therefore there can be no collision between the casting strand and the deflection device.
  • the additional cooling effect by the deflection water can be compensated by the reduction of the downflowing cooling water.
  • heated diverting water can be used.
  • the cooling of the pre-profile strand can be advantageously influenced by adjusting the deflection water temperature.
