Definitions

  • the invention relates to a mold divider for installation in a mold.
  • a metallic melt is poured into a cooled mold, in which the solidification of the melt begins.
  • surface areas of the melt solidify to form a so-called strand shell, which encloses a still liquid metal core.
  • a metallic casting strand comprising the strand shell is pulled out of the mold and is then cooled further.
  • a mold divider is understood to be a device which divides the mold interior into two subspaces, in each of which a casting strand of reduced width can be produced, so that in particular two casting strands can be pulled out of the mold at the same time.
  • US 4637452 A discloses a mold divider which can be built into a mold and which is essentially T-shaped with a beam section and a central section extending centrally from the beam section. After installation in the mold, the central section divides the mold interior of the mold and the beam section lies on top of opposing mold walls between which the mold interior runs.
  • the disadvantage of this is that the installation of the mold divider in the mold or the removal of the mold divider from the mold cannot take place in the installed state of the mold on the continuous casting machine, but rather the mold is first dismantled from the continuous casting machine and brought to a maintenance area, there the Modification (installation or removal) of the mold divider is carried out and then the modified mold is only returned to the continuous caster is assembled.
  • a particularly disadvantageous aspect is the time-consuming retrofitting of the so-called "top feeding" of a cold strand into the continuous casting installation, ie when the cold strand is introduced into the mold from above (from the casting side of the mold).
  • top feeding is not possible in the case of molds with a mold divider, so that the cold strand must always be introduced into the mold from below (from the pouring side of the mold, the so-called “bottom feeding”) before the casting starts .
  • EP 1 206 985 A1 discloses a multiple continuous caster with adjustable slide mold, which for the simultaneous continuous casting of at least two cast strands has at least two mold parts which are variably connected to one another by a displaceable intermediate part.
  • US 3,717,197 A discloses a mold for the continuous casting of several rectangular casting strands and a stationary divider construction with tiltable plates for dividing the mold.
  • JP 2006 247741 A discloses a mold for a continuous caster, an intermediate element for dividing the mold and a connecting structure for fixing the intermediate element.
  • GB 1,400,318 A discloses a method of casting a hollow metal block using a mold having a cooled wall and a mandrel, the cooled wall surrounding the mandrel and together with the mandrel defining an annular mold cavity.

H. from the sprue side of the mold, into the mold or out of the mold, the at least one cooling channel running in the divider block serving for primary cooling in the mold filled melt to form strand shells on the part of the block, casting strands formed from the melt.
  • the mold divider according to the invention enables the mold divider to be installed and removed when the mold is installed in a continuous casting installation.
  • the cooling channels achieve uniform cooling of the strand shell of the casting strand, which has a very positive effect on the quality of the casting strand and also greatly reduces the risk of casting breakouts.
