Definitions

  • the invention relates to a device for continuous casting of molten metal, especially steel melts, to cast tape with two counter-rotating, axially parallel Casting rolls, one formed between them Limit pouring gap, and with plate-shaped Side seals covering the casting gap and the one above it standing melt sump on their from the casting rolls seal the free ends.
  • the object of the invention was based on the above-described prior art Availability of a device for potting Metal melt to improve a cast tape.
  • side seals therefore consist of hard, highly wear-resistant refractory material.
  • a Casting device designed according to the invention can be so the rubbing of the moving Side sealing reduced to a minimum.
  • a zirconium oxide ZrO 2 , zirconium diborite ZrB 2 , aluminum oxide, silicon carbide or mixtures of these refractory materials are suitable as materials for the side seals.
  • such a refractory material can contain additional carrier materials, such as graphite or the like, which are required for embedding the hard material parts in a suitable matrix.
  • elements required for stabilizing the respective component such as calcium oxide CaO, can be present in the material. It is essential that the material used in each case has a sufficiently high hardness and, as a result, good wear resistance in order to reduce the abrasion caused in the area of the contact surfaces to a minimum and at the same time to enable the highest possible contact pressure.
  • This material can be one highly wear-resistant steel, for example belongs to the group of stellites or manganese steels.
  • the hard layer can be made highly wear-resistant ceramic material, the for example chromium carbide and / or tungsten carbide exhibit. It is also conceivable that others are sufficient hard metals such as titanium or their Alloy as a material for the hard layer too use.
  • Layers can be in the form of disks or rings on the relevant end face with the help of suitable Fasteners, such as screws, rivets or bolts, be mechanically attached.
  • suitable Fasteners such as screws, rivets or bolts.
  • the layer can also pass through Cladding or similar Coating processes are applied.
  • the device 1 for casting a steel strip B has two axially parallel to each other and in opposite directions casting rollers 2, 3 rotating relative to one another, which the Long sides of one trained between them Pouring gap 4 and the arranged above Limit melt pool 5.
  • the two side, from the casting rolls 2.3 free transverse sides of the casting gap 4 and of the melt pool 5 are by one Side seal 6.7 sealed.
  • the side seals 6,7 are special hard, wear-resistant ceramic refractory material manufactured. They have the shape of a circular disk and are around an axis parallel to the axes of rotation 8.9 Casting rollers 2,3 aligned axis of rotation 10 movable stored. Their diameter D is such that they have the Pouring gap 4, the melt sump 5 and each of them assigned end faces 11, 12 and 13, 14 of the casting rolls 2.3 over one for proper sealing cover sufficient area.
  • Drive devices can the side seals 6.7 be set in motion so that they are relative to the end faces 11, 12 and 13, 14 respectively assigned to them of the casting rollers 2,3 rotate.
  • the casting rolls rotate 2, 3 in the opposite direction so that those forming on them Shells made of solidified steel together with flowable melt in a downward direction Movement in the casting gap 4 are promoted.
  • the 10th rotating side seals 6.7 each with a high Compressive force P against the end faces assigned to them 11.12 and 13.14 of the casting rolls pressed. In this way are also not limited by the casting rolls 2, 3 lateral ends of the casting gap 4 securely sealed.
  • the cast strip B formed in the casting gap 4 is over a not shown conveyor of the other Processing fed.
