Definitions

  • the invention relates to a device for continuous casting with a revolving mold, which is provided with at least one rotating mold.
  • the strand to be cast mitturade molds not only have molds in the form of two rotating plate chains with mold elements that complement each other to form a cross section of the casting strand defining, circumferentially closed mold space, but also molds with a circumferential, substantially horizontal steel strip on which is poured for the continuous casting of metal strips the molten metal.
  • the lateral outflow of the molten metal is prevented by lateral block chains of copper, resulting in difficulties in sealing between the steel strip and the block chains, because there is a risk that the thin steel strip under the high temperature load on the one hand by the molten metal and on the other hand distorting the spray water cooling necessary to cause the belt-like strand to solidify on the rotating steel belt during its conveyance.
  • the associated thermo-mechanical stress of such molds is therefore very large and leads to relatively short service life.
  • the invention is therefore an object of the invention to provide molds whose molds can be acted upon with a spray water cooling, without running the risk of having to accept a thermal overload and thus an unacceptable deformation of the molds in purchasing.
  • the invention solves the problem set by the fact that the rotating mold has a plate chain of individual mutually articulated plates, which are composed of the outer peripheral shape of the strand sections determining shell molds made of copper and steel straps which form along the joints between the shell molds, mutually articulated legs, and that the shell molds have on opposing abutment surfaces a groove and an engaging groove in the groove.
  • the formation of the shell molds made of copper as a good conductor of heat allows intensive cooling of cast onto the mold shells strand, the strength of the plates of the plate chain is achieved by running along the joints between the shell molds, hinged together legs of the steel support, in the conventional Art can be supported on guide rails, for example via rollers.
  • the exposure of the mold shells made of copper with water spray for intensive cooling of the cast strand is freely possible between the legs of the steel beam.
  • the bumps between the shell molds are on the opposing ones by grooves engaging on one butting surface and in these grooves Shock surface of adjacent shell molds secured in the manner of a labyrinth seal against the ingress of spray into the mold cavity of the shell molds.
  • the advantage of the guided, against spray water sealed, circumferential molds can also be used for co-rotating molds that form a circumferentially closed mold space, so that even with these molds simple spray water cooling can be performed.
  • the mold only needs to have for this purpose only at least two peripheral molds, the plate chains are provided with complementary to form a circumferentially closed mold cavity shell molds.
  • the shell molds in the region of the steel legs in the chain longitudinal direction extending, against the legs have open through recesses for cooling liquid, so that the shell molds made of copper can be applied in the region of these steel support with water spray.
  • the mold after the Fig. 1 to 3 has a revolving mold in the form of a plate chain 1, which is composed of individual mutually hingedly connected plates 2.
  • the plates 2 are formed by shell molds 3 made of copper and steel supports with legs 4, 5 which extend along the joints 6 between the shell molds 3.
  • the tightly juxtaposed legs 4, 5 of the steel support adjacent plates 2 are hinged together, the hinge pins 7 are also used as bearing axles for rollers 8, which are supported on the chain length on guides 9, as the Fig. 2 can be removed.
  • the shell molds 3 are provided with a groove 10 and a spring 11 on opposite abutting surfaces, so that there is a tongue and groove connection between the individual shell molds 3, as is also apparent from the Fig. 2 can be removed.
  • joints 12 between the articulated legs 4, 5 are preferably offset relative to the joints 6 between the shell molds 3 in the longitudinal direction of the chain, there is a relation to splashing particularly dense connection between the individual plates 2 of the plate chain 1, thus by an act of Shells 3 can be cooled intensively with spray water.
  • the shell molds 3 are provided with raised side walls 13 for lateral delimitation of the strip-shaped strand.
  • the shell molds 3 thus determine the outer peripheral shape of the belt-shaped strand to be cast, which is poured into the upwardly open mold space 14 of the shell molds 3 and is cooled during its promotion in the revolving mold, in order to deduct a solidified tape from the mold.
  • connection of the shell molds 3 made of copper with the legs 4, 5 of the steel support can be done in a simple manner via cap screws 15 which are provided in undercut grooves 16 on the side facing away from the mold space 14 of the shell molds 3 in the chain longitudinal direction. These grooves 16 also form passage recesses 17 for cooling fluid, so that in a spray water cooling the spray can also reach in the region of the legs 4, 5 to the shell molds 3.
  • the mold comprises two circumferential molds, each with a plate chain 1, wherein the plates 2 of the two plate chains form 1 shell molds 3, which face each other and complement each other to form a circumferentially closed mold space 14, as shown in Fig. 4 is indicated.
  • the two plate chains 1 are analogous to the plate chain 1 after the Fig. 1 to 3 built, but with a revolving mold for vertical casting results, as the Fig. 4 clarified. Also in this case, the advantages of the revolving plate chains 1 with respect to the watertight execution of the between the shell molds 3 opposite plates 2 of the plate chains 1 resulting mold space 14 can be utilized.
