Definitions

  • the invention relates to a mold with a mold divider for installation in the mold and a method for the simultaneous continuous casting of two casting strands using the mold and the mold divider.
  • the invention relates to a method for the continuous casting of two casting strands in a mold using the mold and a mold divider.
  • 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 mean 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 the mold Chill mold, in particular two casting strands can be pulled out 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 takes place and then the converted mold is only reassembled on the continuous caster.
  • the costly conversion during the so-called "top feeding" of a cold strand into the continuous casting plant is particularly disadvantageous. H. when inserting the cold strand from above (from the casting side of the mold) into 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 .
  • a generic mold divider which can be installed in a mold from the sprue side within a relatively short time.
  • the rapid installation and removal of the mold divider enables the top feeding of a cold strand into the mold.
  • 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.
  • 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.
  • the invention has for its object to provide a further improved system consisting of a mold and a mold divider for installation in the mold.
  • a further improved system consisting of a mold and a mold divider for installation in the mold.
  • the time for removing the mold divider from the mold, introducing the cold strand from the pouring side into the mold (“top feeding”) and installing the mold divider into the mold should be further reduced. This should make the top feeding of molds with mold dividers more attractive.
  • the mold divider can be inserted into and removed from the mold much more quickly.
  • first clamping piston which is arranged opposite a first mold wall
  • second clamping piston which is arranged opposite a second mold wall.
  • the clamping pistons engage the mold walls through mold wall openings.
  • the mold walls are typically broad side walls of a slab mold.
  • Each clamping piston is e.g. driven hydraulically, pneumatically or electromechanically, so that the piston rod of the clamping piston can be moved along its longitudinal axis towards the divider block and away from the divider block.
  • the piston rod of the clamping piston By moving the piston rod of the clamping piston, the divider block can be clamped in the mold via a clamping rod.
  • the installation and removal of the mold divider can thus be largely automated, since there is no need for manual clamping by means of the clamping wedge and manual screwing of the holding element.
  • the mold has several, for example two, first clamping pistons and several, for example two, second clamping pistons. Since the divider block in the casting direction is approximately as long as the mold wall, it is advantageous to clamp the divider block several times in the casting direction. This distributes the clamping force evenly on the mold wall and the divider block in the casting direction.
  • the at least one first clamping piston is arranged centrally to the first mold wall and the at least one second clamping piston is arranged centrally to the second mold wall.
  • the clamping force is evenly distributed on the mold wall and the divider block in the width direction.
  • a clamping rod can be guided through a clamping piston recess in the at least one first clamping piston and the at least one second clamping piston. This ensures that the clamping bars can be replaced with each other and only one spare part needs to be in stock.
  • the mold In order to be able to set the clamping force in a targeted manner, it is advantageous for the mold to have at least one force regulator for regulating the clamping force of at least one first clamping piston and / or at least one second clamping piston.
  • the force regulator is a pneumatic or hydraulic pressure regulator.
  • the object according to the invention is also achieved by a method for the simultaneous continuous casting of two casting strands in a mold using the mold and a mold divider.
  • the cold strand is introduced into the mold without a mold divider by "top feeding", so that the cold strand head of the cold strand lies below the pouring side of the mold. Then the mold divider is installed in the mold. Finally, the cold strand head is inserted into the mold from the pouring side against the casting direction, so that the mold divider projects into the cold strand recess and the two subspaces of the mold are sealed in a fluid-tight manner.
  • the mold divider when the mold divider is installed in the mold, the mold divider is first inserted into the mold from the sprue side without the clamping rod, then the at least one first clamping piston is moved to the divider block of the mold divider, then the clamping rod from the sprue side through the clamping piston recess of the at least guided a first clamping piston, and then move the first clamping piston away from the divider block until the clamping rod is clamped in the clamping piston recess of the at least one first clamping piston.
  • the at least one second clamping piston is moved to the divider block of the mold divider, then a further clamping rod is guided from the sprue side through the clamping piston recess of the at least one second clamping piston, then the at least one second clamping piston moves away from the dividing block until the Clamping rod is clamped in the clamping piston recess of the at least one second clamping piston.
  • the second clamping piston is moved first, the clamping rod is inserted and the clamping rod is clamped in the clamping piston recess of the second clamping piston before the same steps are carried out with the first clamping piston.
  • a mold divider built into the mold is removed from the mold before the cold strand head is passed through the mold.
  • the clamping of the first and / or second clamping piston is set in a force-controlled or force-controlled manner. It is particularly advantageous if the clamping is set by a pneumatic or hydraulic pressure regulator. Hydraulic or pneumatic pressure regulators are known to the person skilled in the art, e.g. The specialist books Fundamentals of Fluid Power - Part 1: Hydraulics and Part 2: Pneumatics, well known and are characterized by their particular robustness. In addition, the mold oscillates anyway hydraulically, so that the additional effort is low.
