Definitions

  • the invention relates to a seal for refractory, metallic melt leading components, in particular for tubular components used on spouts of metallurgical vessels, which engage in one another in a sealed manner and are individually replaceable.
  • Interlocking metallic melt-guiding components such as a pouring tube, which is connected to the outlet of an outlet closure for metallurgical vessels, are usually sealed by means of a flexible, elastically yielding end face seal.
  • the object of the present invention is to improve the seal on intermeshing, melt-carrying components with simple means with the aim of eliminating the difficulties outlined and, above all, preventing fluid flows in the seal area.
  • the object is achieved according to the invention in that in the sealing area at least on one of the interlocking components at least one in one An annular spring bearing ring groove and an overlap at the open ends is arranged, which rests radially resiliently against the other component.
  • the clearance fit or the clearance between the two components for the flow of media is effectively shut off, so that the melt flow can neither suck in air from the outside nor melt itself can get between the components.
  • the clearance fit can be selected so that the components can easily be mutually adjusted under operating conditions.
  • a dense ceramic material preferably an oxide ceramic material and in particular zirconium oxide, is suitable as the material for the production of the ceramic spring ring.
  • 1 and 2 denote two tubular, interlocking refractory components for conveying metallic melt. Between the two components 1 and 2 there is a clearance fit 3, the clearance between them based on the respective application.
  • the components 1 and 2 are designed to form a releasable refractory seal, possibly with parts 1 and 2 which are movable under operating conditions.
  • an open ceramic spring ring 4 with a radial cross-section in the spring force is arranged in a circumferential ring groove 5 of the inner component 2.
  • the spring ring 4 has a fold-like overlap 6, which is transverse to the ring thickness, with free spaces 7 that compensate for the spring travel, so that the peripheral surface of the spring ring 4 acting as a sealing surface 8 lies sealingly against the inner surface 9 of the outer component 1, as a result of which fluid leaks through the clearance fit 3 do not come about.
  • the sealing surface 8 of the spring ring 4 and the counter-sealing area of the inner surface 9 of the outer component 1 can be finished; the inner surface 9 as far as possible to the insertion end of the component 1 in order to facilitate the joining and detaching of the components 1 and 2.
  • a spring ring 4 is used, similar to a piston ring, which in the relaxed state has open spaces 7 which close proportionally when loaded.
  • the seal according to FIG. 4 is equipped with a spring ring 10 which is closed in the tension-free state and which is supported in an annular groove 5 of the outer component 1 and with its inner sealing surface 11 opposite seals the outer surface 12 of the inner member 2 while the overlapped ends open under load.
  • a combination application of both spring washers 4 and 10 in annular grooves 5 has the seal of two inner components 2 abutting one another on the end face within an outer component 1 according to FIG. 5.
  • One of the spring washers 4 and 10 is arranged on one side of the joint 13 of the two inner components 2 held together by means of an elastic mineral fiber seal 14 and is surrounded by the outer component 1.
  • This has a radial bore 15 between the spring washers 4 and 10 with a fluid connection 16 for supplying, for example, a sealing gas in the region of the clearance 3 between the spring washers 4 and 10.
  • Such seals with an additional fluid connection 16 can be used on melt feeds of horizontal continuous casting plants be required to prevent air from entering the melt stream.
  • the seal of the air fit in the clearance 3 serves the same purpose as shown in FIG. 6 on the cone connection between the lower plate 17 of one of the slide closures (not shown for the sake of simplicity) and a pouring spout 18.
  • the spring ring 19 used there shown enlarged in FIG unclamped state is largely closed, rests in an inner annular groove 20 of the head of the pouring spout 18 and lies with its conical sealing surface 21 on the connecting cone 22 of the lower plate 17, between which opposite flat surfaces of the connecting cone 22 and the pouring tube head, an elastic mineral fiber seal 23 can also be provided.
  • FIG. 8 illustrates an application example of a pouring closure for metallurgical vessels, which has a non-rotatable pouring part 25 arranged vertically in the bottom 24 of the vessel, through which melt 27 flows out via transverse bores 26 from the inside of the vessel as soon as corresponding bores 28 in an outer component which can be adjusted about the axis 29 30 are more or less congruent.
  • This component 30, which is designed as a turned part, is placed over the pouring part 25 in a pot-like manner and carries on the inside in annular grooves 31 spring washers 32 which bear against the peripheral surface 33 of the inner pouring part 25 and shield the clearance fit 3 against a flow of the melt 27.
  • the spring washers 32 serve as a guide for the outer component 30 when the latter is rotated about the axis 29 for the purpose of regulating the melt flow.
