Definitions

  • the invention relates to a dip tube according to the generic term of Claim 1.
  • the mold consists of broad walls and Narrow side walls that extend the wide side walls by a distance of 50 Hold up to 100 mm and limit the narrow sides of the strand.
  • the Immersion pipes have been adapted to the mold format in such a way that the Immersion pipes first of all from a connection to the casting tank Pipe section exist, which in the direction of the narrow side walls of the Mold extended in cross-section and in a direction perpendicular to it is reduced.
  • Dipping spouts with outlet openings are common, that point in the direction of the narrow sides (see DE 37 09 188 A1) or also have more in the casting direction, as is the case, for example, in EP 0 403 808 A1 is known.
  • Last but not least, diving spouts are common, too have a pouring spout in the pouring direction (see Steel and Iron (1991), No. 9, p. 107). These diving spouts allow a satisfactory Operation at a strand lowering speed of up to 3 m / min.
  • the invention is therefore based on the object of a diving spout develop that avoids these disadvantages and the use of higher Line lowering speeds of up to 6 m / min allowed at String dimensions from 50 to 100 mm thick and 600 mm to 2000 mm wide and above.
  • the immersion pouring tube consists of a upper tubular section 4, to which another section 4 ' connects.
  • Section 4 'of the immersion pouring tube is in one plane flared and has a wedge-shaped center Provide bottom piece 3.
  • Those protruding into the dip tube Side surfaces 3 'of the bottom piece 3 form together with the inner walls 1 of the expanding part 4 'flow channels 7.
  • the axes 8 of the Flow channels 7 each close with the dip tube axis 9 Angle between 10 and 22 °.
  • the Broad side walls 2 a distance from each other between 50 to 100 mm , the angle in question is selected in such a way that the angle of 10 ° a distance between the narrow side walls 2 'of Mold of about 600 mm and the larger angle a distance of Narrow side walls of the mold of 2000 mm and more are assigned.
  • the outlet openings of the channels 7 lie in a plane perpendicular to the Immersion tube axis 9.
  • an embodiment is also conceivable in which the plane of the outlet openings of the channels 7 perpendicular to the axes 8 the channels 7 are arranged.
  • the position of the channels 7 of section 4 'of the immersion pouring tube is through defines the angle ⁇ that one of the channel axes 8 with the Immersion tube axis 9 includes.
  • Slab width Angle between axes 8 and 9: 600 to 1000 mm 10 to 15 ° 900 to 1400 mm 13 to 19 ° 1200 to 2000 mm 16 to 22 °
  • This free cross-sectional area of the inlet opening of the immersion pouring tube 4 is given by Fig. 1 by the annular gap between the plug 5 and the spout 6 of a casting container, not shown.
  • the spout 6 is embedded in a known manner in the bottom of the casting container and the dip tube 4 is on the bottom plate of the pouring container under the spout flanged. It is advisable to use a seal at the parting line Sealing ring 12 in a recess in the flange 4 ′′ of the immersion pouring tube 4 intended.
  • Fig. 3 shows an embodiment of the immersion pouring tube 4 for the case represents that the immersion pouring tube 4 is inserted into the bottom of the casting container is.
  • the upper section 13 of the immersion pouring tube 4 is conical to the outside expanded scope then corresponds to the spout 6 as shown in Fig. 1.
