Definitions

  • the invention relates to a mold for casting double-T-Vorprofilen whose Kokillen takegang is provided in the direction of flow of the melt with a slight conicity, wherein the mold is made of a one-piece tubular blank.
  • the conicity of Kokillen pressgangs is known to compensate for the resulting shrinkage of the casting within the mold during the solidification process.
  • the generation of this conicity is problematic, especially in large-format double-T pre-profiles or beam-blank profiles, because they are made of a tubular semi-finished material essentially by forming and because such profiles have very large dimensions over 800 mm overall width, about 400 mm flange width and more than 120 mm web thickness. Since casting with such large formats is slower than with smaller formats, it requires a relatively large conicity in the mold.
  • the publication DE-A-1 282 861 refers to a continuous casting mold designed as a double-T-carrier or similar, which consists of multi-part walls.
  • the inner walls of the mold run down towards each other slightly, whereby one always reaches a whopping plant of the solidifying metal as it passes down.
  • the inner walls which are arranged parallel or rounded parallel to the longitudinal center axis, but do not run down to each other and it is so that only a conditional improvement in casting to a double-T carrier achieved.
  • the invention has for its object to provide a mold for large-sized profiles, which is suitable for casting large T-Vorprofile or beam-blank formats, because it meets the associated casting requirements with respect to the taper of the Kokillen shedganges.
  • this object is achieved in that all the inner walls of the mold in the mold pass each have a conicity extending from this upper side to the lower side of the mold in the direction of the mold center.
  • the special cross section of the beam blank profiles means that the degree of shrinkage of the casting strand varies greatly within the profile cross section. For example, it is smaller at the relatively narrow web than in the longitudinal direction of the profile. It is therefore provided according to the invention for optimizing the strand formation that each inner wall is provided with a conically dimensioned as a function of the degree of shrinkage of the casting strand.
  • the invention further provides that the inner walls of the mold are linear, curved, curved, parabolic or similarly shaped.
  • Fig. 1 and Fig. 2 shown conventional mold 1 has a Kokillen pressgang 2 with a double-T-shaped cross section, corresponding to the cross section of the profile to be cast.
  • the mold passage 2 is formed by the inner walls 3a to 3l. Their production takes place with a punch, which is pulled as a negative mold through a tubular blank.
  • Fig. 1 is still dashed lines the lower end of the mold 1 indicated.
  • the inner walls 3a to 3f are produced with a taper 4.
  • the transverse inner walls 3i, 3j and 3k, 31 of this double-T have a taper 5, since only then can the punch be pulled out after forming.
  • the inventive mold 6 after Fig. 3 to Fig. 6 differs from the conventional mold 1 essentially in that in her all inner walls 7a to 71 in Kokillen begang 8 each have from this top to the bottom of the mold in the direction towards the center of Kokillen beganges extending taper 9 to 12.
  • the center axis 1 'itself or the plane transverse to the longitudinal formation of the mold cross section can be understood as the center of the mold passage. Strictly speaking, the solidification of the melt takes place in the mold towards the central axis. In order not to have to provide non-linear surfaces in these inner walls when viewed transversely to the passage 2, however, they can be designed to be linear in this direction in an approximated manner.
  • the central axis may be straight as well as curved when the mold passage forms a radius, in particular when the cast strand is guided by a radius from a vertical to a horizontal plane. The radius or the curvature would run perpendicular to the longitudinal formation of the Kokillen shedganges in the usual way.
  • the inner walls 7a to 7l are formed as curved surfaces. They are shaped with such a curvature that they are adapted to the non-linear over the mold height solidification of the strand cast therein. For example, it may behave in such a way that the strand already solidifies rapidly in the upper region of the mold and then only minimally shrinks. Accordingly, would have these inner walls are already reduced by a relatively large amount in the upper region of the mold and then only minimally changed inwards in the lower region. Therefore, they may be linear, curved, curved, parabolic or similarly shaped as needed.
  • the conicity 9 to 12 of the inner walls 7a to 7l is dimensioned so that it compensates everywhere occurring there shrinkage.
  • Fig. 1 respectively.
  • Fig. 3 the top of Kokillen pengangs with solid lines, while the bottom is shown with dotted lines.
  • Fig. 4 Furthermore, the continuous casting direction is indicated by the arrow above the mold.
  • the mold 6 allows a continuous casting particularly large-sized profiles, because by the inventive processing of Kokillen pressgangs a correspondingly large conicity can be achieved, which is also adapted to the local degree of shrinkage of G hasslesstrangs within the Kokillen shedganges.
  • the mold according to the invention can also be used for casting bony profiles by providing the mold passage with a correspondingly bone-shaped cross section. It is generally suitable for casting large-format profiles, regardless of the cross-sectional geometry of the profile to be cast.
  • the embodiment according to the invention can also be used for repairing or reworking used molds.
