Definitions

  • the invention relates to an immersion casting tube for introducing molten metal, in particular steel melt, into a continuous casting mold having a broad side walls and narrow side walls and forming a strand with broad sides and narrow sides, in particular a thin slab continuous casting mold, the immersion casting tube having a central axis provided with side openings for the metal melt are directed essentially against the narrow sides of the strand, and has a bottom part which is provided with a bottom opening for the molten metal.
  • an immersion pouring tube is known in which two intersecting or intersecting pouring jets emerge from the bottom region or the side region of the immersion pouring tube. According to a further embodiment, pouring jets cross or intersect one another in the interior of the immersion pouring tube before they emerge laterally. Even with these Known immersed pouring pipes fail to achieve the diverging requirements: high pouring rate and low, but sufficient bath movement at the pouring level as well as low vertical penetration depth of the pouring jet into the liquid core of the strand.
  • the invention aims at avoiding the disadvantages and difficulties described above and has as its object to create an immersion pouring tube of the type described at the outset with which, despite high pouring rates, both a low vertical penetration depth of the melt supplied through the immersion pouring tube can be maintained and also due to reduced lateral outflow impulses a small wave formation can be registered at the bathroom mirror, so a calm bathroom mirror is ensured.
  • the edge wave that occurs at the bath level during the casting operation should have only a small height and nevertheless a sufficient melting rate should be achieved for the casting powder covering the bath level.
  • the bottom part has at least two bottom openings directed obliquely against the narrow sides of the strand to form at least two pouring jets, the flow directions of which cross one another - in the viewing direction perpendicular to the broad sides of the strand.
  • the pouring jets emerging from the bottom openings intersect, e.g. either in the area of the bottom part or at a distance below the bottom part of the immersion pouring tube - etc. looking perpendicular to the broad sides of the strand.
  • the pouring jets intersect only with a partial area of the cross section.
  • the pouring jets emerging from the floor area cross each other skewed, etc. either in the floor area or below the floor area at a distance from it.
  • the center axes of the bottom openings expediently form an angle with one another of between 5 and 120 °.
  • the cross sections of the bottom openings preferably have an area fraction between 10 and 70% of the sum of all cross sections of the side and bottom openings.
  • the cross section of the side openings preferably increases in the flow direction and the sum of the outlet cross-sectional areas of all side and bottom openings is equal to or greater than 1.1 times the internal cross-sectional area of the immersion nozzle, measured at the height of the upper edge of the side openings.
  • a smooth, even side flow is achieved in that the upper boundary surfaces of the side openings with an angle ( ⁇ ) between -20 ° ⁇ ⁇ ⁇ 35 ° and the lower boundary surfaces of the side openings with an angle ( ⁇ ) between -30 ° ⁇ ⁇ ⁇ 60 ° are inclined to the horizontal.
  • the lower boundary surfaces are preferably longer than the upper boundary surfaces of the side openings and extend with the extension into the interior of the immersion pouring tube, as a result of which a part of the flow directed downward within the immersion pouring tube is collected while avoiding a jam and directed to the side.
  • the central axes of the bottom openings are arranged inclined in addition to the alignment to the narrow sides of the strand in the direction of the broad sides of the strand and in this direction form an angle between -20 ° and + 20 ° with the central axis of the immersion pouring tube.
  • the cross section of the interior of the tube part of the immersion pouring tube advantageously increases in the direction of flow and in the direction of the narrow sides of the strand and decreases in the direction of the broad sides of the strand.
  • the cross-sectional area of the interior of the tube part of the immersion pouring tube is expediently constant in the flow direction or the cross-sectional area of the interior of the tube part of the immersion pouring tube increases in the flow direction.
  • Fig. 1 shows a vertical section through an immersion pouring tube used in a continuous casting mold, together with the flow conditions that arise here.
  • 2, 3 and 4 show a dip tube according to a first Embodiment in longitudinal section along the line II-II of FIG. 3 and in a longitudinal section perpendicular to this along the line III-III of FIG. 2.
  • FIG. 4 illustrates a cross section near the bottom area according to the line IV-IV of FIG 2.
  • FIGS. 5 to 7 illustrate, in a representation analogous to FIGS. 2 to 4, a further embodiment of an immersion pouring tube;
  • Fig. 8 is a section along the line VIII-VIII of Fig. 5, the sectional plane being in the bottom region of the immersion pouring tube.
  • 9, 10 and 11 show further embodiments of a dip tube, etc. each in a partial sectional view analogous to FIG. 2.
  • An immersion pouring tube 1 is inserted into the bottom of an intermediate vessel 2 and extends with its mouth part or bottom part 3 into a continuous casting mold 4 which, according to FIG. 1, has a cross section for casting a strand 5 with the cross section of a thin strand (approximately in the order of magnitude of 70 mm x 1500 mm).
  • the continuous casting mold is accordingly formed by narrow side walls 6 and wide side walls 7, on which the narrow sides 8 and wide sides 9 of the strand 5 form.
  • the mouth part or bottom part 3 of the immersion pouring tube 1 is immersed under the surface 10 of the molten metal 11 (molten steel).
  • the surface 10 of the molten metal 11 is covered by a casting powder 12.
  • a still thin strand shell 13 is formed, within which the liquid core 14 of the strand 5 is located.
  • the immersion pouring tube 1 has, as is particularly clear from FIGS. 2 to 4, a vertically directed tube part 15 which encloses an interior 16.
  • This interior 16 has a cross section, the dimensions of which are directed parallel to the broad side walls 7 of the continuous casting mold 4 and increase in the casting direction 17; On the other hand, decrease in a direction perpendicular to this, i.e. parallel to the narrow side walls 6, and so on. starting from an approximately circular or square cross-section to a narrow rectangular or oval cross-section in the bottom part 3 of the immersion pouring tube 1.
  • the cross-sectional area of the interior remains largely constant when viewed in the casting direction 17 or increases slightly.
  • the immersion pouring tube 1 has two side openings 18 for the molten metal, one of which is directed towards a narrow side wall 6 of the continuous casting mold 4 or the narrow side 8 of the strand 5.
  • the side openings 18 have upper and lower boundary surfaces 19, 20, the upper boundary surface 19 with respect to the horizontal an angle ⁇ between -20 ° and 35 ° and the lower boundary surface 20 one Include angle ⁇ between -30 ° and 60 °.
  • Downward-sloping boundary surfaces 19, 20 are preferred, as shown in FIG. 2, the cross section of the side openings 18 increasing in the direction of flow.
  • each side wall opening 18 is longer than the upper boundary surface 19, the lower boundary surfaces 20 extending into the interior 16 of the immersion pouring tube 1 with their extension. As a result, a large part of the molten metal flowing downward in the interior 16 is caught and directed to the side openings 18.
  • the central axes 25 of the bottom openings 23 being at an angle ⁇ between 5 and Cut 120 °.
  • the central axes 25 could also cross each other skew.
  • the sum of the outlet cross-sectional areas of the side opening 18 and the bottom openings 23 is equal to or greater than 1.1 times the interior cross-sectional area of the immersion pouring tube, which is measured at the upper edge of the side openings.
  • the central axes 25 of the bottom openings 23 can also be arranged inclined in the direction of the broad side walls 7 of the continuous casting mold 4 in addition to the alignment with the narrow side walls 6 of the continuous casting mold 4.
  • the projection of the central axis 26 and the central axes 25 of the bottom openings 23 onto a plane parallel to the narrow sides 8 shows an angle ⁇ between -20 ° and + 20 °.
  • the central axes 25 of the pouring jets 24 emerging from the bottom openings 23 can intersect or cross each other skew, so that the pouring jets 24 only overlap one another with a part of their cross-sectional areas.
  • the cross sections of the bottom openings 23 have an area fraction between 10 and 70% of the sum of all cross sections of the side 18 and bottom openings 23.
  • the function of the immersion pouring tube 1 is as follows:
  • the desirable upper vortices 27 are formed, which ensure that the casting powder 12 applied to the bath surface 10 melts satisfactorily, and due to the reduced lateral outflow impulses, small heights of the edge wave 28 that is produced can be recorded.
  • the vertical depth of penetration of the downwardly directed pouring jets 24 is low, since they either combine to form a strongly fanning and dissipative mixing jet 29 or, in the case of a skewed intersection of the central axes of the pouring jets, give off energy to the resulting rotary movement.
  • the downward pouring streams 24 encounter the upward movement of the lower vortices generated by the lateral pouring streams 22, whereby a flow pattern with large vortices in the lower mold region, which would result if there were only side openings, breaks down into a flow pattern with small vortex turbulences.
  • the impingement pulse on the strand shell 13 is much smaller, which also reduces the melting of the strand shell 13 of the strand 5.
  • the central axes 25 of the pouring jets 24 emerging from the bottom region 3 cross skew so that the pouring jets 24 only intersect or touch one another below the bottom region 3 with their peripheral edge regions.
  • the middle part 30 of the bottom part 3 present between the bottom openings 23 forms a wedge-shaped recess 31 in the interior 16 of the immersion pouring tube 1.
  • the middle part 30 of the bottom region 3 arranged between the two bottom openings 23 is wedge-shaped upwards, whereby the deflection of the molten metal 11 flowing downward in the interior 16 of the immersion pouring tube 1 is extended to the side openings 18 and is also improved to the bottom openings 23. This largely prevents congestion losses.
  • the two pouring jets 24 emerging from the bottom area 3 already partially intersect within the bottom area 3, which means that for certain casting conditions the spreading area of the resulting mixed jet below the bottom area can advantageously be set.
  • FIG. 5 shows, instead of the central depression 31, an upwardly wedge-shaped part 32 can be attached in order to guide the flow without loss (cf. FIG. 11).
