Definitions

  • the invention relates to a method for. Collecting and discharging drainage water from the inner bow of the strand guide a beam blank casting machine, in which the cast strand brought to solidification and the required heat dissipation is achieved inter alia via splashing, possibly collects on the inner arc of the strand drain water and the drain water using a suction head is collected and sucked off and the extracted water-air mixture in water and air is separated.
  • the invention also relates to a device for carrying out the method.
  • the current state of the art is characterized for example by blowing out the water from the inner arc of the strand by means of compressed air. This blowing out takes place under high energy consumption and with considerable maintenance effort for compressors required to produce the required amount of compressed air. Furthermore, the uncontrolled water blown over the flange edges of the Beam Blank pre-profile damages the quality of the produced profile, which can cause material losses.
  • a sloping surface for rejecting excess cooling water is arranged above the inlet suction pipe, which divides over the inlet suction pipe in opposite transverse directions, so that cooling water residues drain on both sides of the casting strand and must be collected separately.
  • beam blank profiles or pre-profile strands such as carrier pre-profiles or rail pre-profiles are shaped so that residual water quantities can not escape independently via the lateral flange edges. Because the space and space conditions are already very cramped by the conditions in the cooling chamber and within the strand guide, there is a lack of space to install expensive devices to remove the spill water can. A diversion of the water through corresponding devices for feeding into suction pipes is extremely difficult due to the constantly moving rough strand surface.
  • the suction device has a flat intake manifold mouthpiece corresponding to the strand width, which is under negative pressure.
  • a separator for collecting the extracted water residues and contaminants is turned on in the flow direction.
  • the invention in a method for collecting and discharging drainage water from the inner arc of the strand guide a beam blank casting machine according to the features of the preamble of claim 1, the collected in the suction head drain water using fluidizers or Pululhememmern fluidizing, wherein fluidizers are formed with a plurality of air nozzles arranged distributed in the suction head and the suction head is shaped in such a way that a fluidization space is formed for expansion of the water to be absorbed.
  • the drain water is fluidized within the suction head and made pneumatically eligible.
  • the fluidizing of the drainage water this can be sucked with low energy expenditure and then fed to a separator for water and air.
  • the formation of a suction head means a straightforward and space-saving design that can be installed with little effort in the Beam Blank casting machine.
  • the invention proposes that the suction head is guided and / or positioned by means of a manipulator in or on the strand, which makes it possible for the suction head from a greater distance and from a control room to be optimally positioned. Use is controlled.
  • sealing means such as brushes or rubber-elastic sealing strips are expediently proposed.
  • the suction head Since beam blank casting machines can be used for different strand formats, it is expedient according to a further proposal of the invention for the suction head to be adaptable to the different strand formats and to be mounted for connection to a suction device using quick-release or connection means.
  • the invention also relates to a device for carrying out the method.
  • This device with the features of the preamble of claim 6 is characterized by fluidizers and means for guiding the suction head along the beam blank Vorprofils. With the help of such trained suction cups the drain water is made pneumatically eligible and sucked Water can pass through the induced draft via suitable pipes or lines up to water separators transported and forwarded from there or be returned after appropriate cleaning in the cooling device of the casting machine.
  • the suction head is designed in the manner of a bell-shaped receiving space, wherein the receiving space containing the fluidizers such as nozzles, loose metal parts or chains for fluidizing the collected water.
  • the receiving space containing the fluidizers such as nozzles, loose metal parts or chains for fluidizing the collected water.
  • This arrangement allows for a very compact design of the suction head, so that it can be accommodated in the strand guide space-saving. It is advantageous if in several areas of the continuous casting suction cups are arranged, which suck the drain water early from the inner arc of the beam blanks
  • a particularly advantageous embodiment of the suction device provides that the suction head is designed by means of quick release or connecting means as a replaceable head for adaptation to other beam blank formats. Since different Beam Blank pre-profiles are cast especially during the rolling of carriers, the measure proposed here for adapting the suction head is particularly interesting.
  • suction device An optimized use of the suction device is obtained when a manipulator is provided for positioning the suction head, wherein the suction head can be positioned at a distance of 0 to 40 mm from the surface of the beam blank format. By this measure it is avoided that the suction head comes into contact with the in some cases very rough surface of the beam blanks and either the beam blank itself or the suction head is damaged.
  • FIG. 1 shows the strand section for a beam blank, in the present case a carrier pre-profile.
  • the reference numeral 12 denotes the casting direction of the beam blanks.
  • the side edge profiles of the beam blanks are provided with the reference numerals 11 and 11 '.
  • the suction head 1 is located for the purpose of sucking off the surplus and drainage water collected therein.
  • the suction head 1 can be connected to the suction device 4 with quick-release or connecting means 3.
  • This consists of the suction line 10 and a water separator 13.
  • the suction line 10 is in - as mentioned - connected to a separator in which the collected water-air mixture is separated into water and air, after which the water content prepared for the purpose of reuse, d. H. separated from entrained solids and other materials and recycled for reuse of the Beam Blank Caster.
  • the suction head 1 is formed in bell shape with a lower suction opening and surrounds a fluidization space for expansion of the water to be absorbed. Furthermore, the suction head 1 contains in its interior for fluidizing the collected in the suction head 1 drain water so-called fluidizers or pulse inhibitor, whereby the drain water is made pneumatically eligible.
  • the fluidization of the collected drainage water is preferably improved in that air nozzles distributed in the suction head are present within the bell-shaped fluidization space for the purpose of expanding the water to be absorbed. With their help, the water to be collected is vigorously aerated with air and is thus made pneumatically eligible.
  • the fluidizers may also include chains or similar mechanical devices.
  • the strand guide 8 comprises a mold and below it a row of strand guide segments 6, 6 ', 6 "to 6 n .
  • Such manipulators may be guided by electrical or electromagnetic pulses such that between the suction head 1 and the profile 9 Strand guide 8 always a same distance, preferably a distance of 0 to 40 mm to the strand surface, is maintained during the absorption of the drain water.
  • the suction head 1 is resiliently adapted against the strand 2 using brushes not shown.
  • Different suction heads 1, which are to be adapted to different formats of the beam blank pre-profile 9, can be coupled to the suction line 10 by means of a quick release means or connecting means.
