Definitions

  • the invention relates to a mold tube made of copper for the continuous casting of metals according to the features in the preambles of claims 1 and 4.
  • the prior art includes mold tubes with rectangular inner and Outside cross sections and with rounded longitudinal edge areas, which a nominal wall thickness, which is 8% to 10% of the distance from the Pipe mouth is mutually frontal inner surfaces.
  • the invention is based on the object to create mold tube made of copper for the continuous casting of metals a perfect transfer, especially at casting speeds> 2.5 m / min ensures the heat from the metal to be poured into a cooling medium.
  • the wall thickness of the rectangular mold tube in the longitudinal edge areas opposite the wall thickness in the wall areas between the longitudinal edge areas by 10% to 40% sized smaller.
  • This measure means that even at casting speeds > 2.5 m / min, the heat generated flawlessly to the respective Cooling medium can be transferred, regardless of whether a Cooling medium in a gap between a mold tube and the mold tube surrounding jacket is guided whether the cooling medium in cooling channels in the wall of a mold tube flows or whether the outer surfaces of a mold tube be sprayed directly with a cooling medium.
  • the wall thickness is preferred in accordance with the features of claim 2 Longitudinal edge areas compared to the wall thickness in the wall areas between the longitudinal edge areas by 25% to 30% smaller.
  • the reduction in wall thickness can vary over the entire length of a mold tube extend.
  • the wall thickness reduction in the Longitudinal edge areas is limited to a height range in which the respective bath level of the liquid metal.
  • the wall thickness of the mold tube in Height range of the bath level of the liquid metal over the entire circumference 10% to 40% of the nominal wall thickness reduced.
  • the cross section of the Chill pipe can be polygonal, e.g. be rectangular or round.
  • this is also the preferred one Wall thickness reduction 25% to 30% of the nominal wall thickness.
  • the bathroom mirror is in Mold tube in a height range that extends from the fill face up to about 500 mm from the front of the filler.
  • the level of the bathroom mirror is based on the characteristics of the Claim 7 preferably between 80 mm and 180 mm below the Filling end.
  • 1 is a mold tube made of copper for the continuous casting of Metals, especially steel, referred to.
  • the mold tube 1 has a rectangular inside and outside cross section with the inside and outside rounded longitudinal edge areas 2.
  • the so-called nominal Wall thickness WD of the wall areas 3 between the longitudinal edge areas 2 8% to 10% of the distance A at the pipe mouth 4 opposite each other lying inner surfaces 5.
  • the wall thickness WD1 in the longitudinal edge areas 2 is opposite the wall thickness WD in the wall areas 3 between the longitudinal edge areas 2 by 10% to 40% smaller.
  • the different wall thicknesses WD and WD1 of the mold tube 1 of FIGS. 1 and 2 are present over the entire height H (length) of the mold tube 1.
  • the cooling of the mold tube 1 can be according to one indicated in FIG first embodiment are carried out by a cooling medium which has a gap 6 flows through, between the outer surface 7 of the mold tube 1 and one Sheath 8 is formed, which envelops the mold tube 1 with a defined distance A1.
  • a second embodiment shown in FIG. 2 looks into the wall areas 3 of the mold tube 1 introduced longitudinal channels 9, which with a suitable Coolant to be applied.
  • FIG. 2 shows an embodiment of a cooling method, at which the outer surfaces 7 of the mold tube 1 in partial areas or are cooled overall by means of a cooling medium which is placed on these surfaces 7 is sprayed from nozzles 10.
  • FIG. 3 shows a mold tube 1a made of copper for the continuous casting of metals, in which the reduction in wall thickness in the longitudinal edge areas 2 to one Height range 11 is limited, in which the level of not closer illustrated bath level of the liquid metal.
  • This height range 11 generally extends between the filling face 12 of the mold tube 1a and an area that is approximately 500 mm below the filler face 12.
  • the cooling of the mold tube 1 a can take place like the cooling of the mold tube 1. In this respect, there is no need for another explanation.
  • a mold tube 1b made of copper for the continuous casting of Metals according to Figures 4 and 5 is not closer to the height range 14 of the illustrated liquid metal bath level the wall thickness WD2 Pipe wall 16 over the entire circumference to 10% to 40% of the nominal Wall thickness WD3 reduced.
  • This height range 14 extends from the Filling end face 12a from about 500 mm in the direction of the pipe mouth 4a.
  • the Bathroom mirror as such is usually in a height range 15 between 80 mm and 180 mm below the fill face 12a.
  • the nominal wall thickness WD3 is 8% to 10% of the distance A2 of the frontally opposite one another at the pipe mouth 4a inner surfaces 5a.
  • FIGS. 4 and 5 of a mold tube 1b can thus be cooled be, as was explained with reference to Figure 2. In this respect, one repeated description can be omitted.
