Definitions

  • the invention relates to a connection between the outlet of a metallurgical vessel and an adjoining protective tube or an immersion spout, the outlet and the protective tube or the immersion spout being connected to one another by a seat and in the region of the seat an annular space concentric to this with a supply line for a Inert gas is arranged and a seal is provided.
  • DE 36 20 413 C2 proposes an expandable fiber felt for pouring closures and gas inlets on metallurgical vessels.
  • the object of the invention is to simplify the sealing in a connection of the type mentioned and to achieve tightness monitoring.
  • the above object is achieved with a connection of the type mentioned at the outset in that a compressible ring is arranged as a sealing ring above and below the annular space and that a display device for a gas pressure present in the annular space is arranged in the feed line of the inert gas.
  • the sealing rings ensure the necessary tightness of the seat even if there are unevenness between the outlet and the protective tube or immersion spout. In cooperation with the gas pressure of the inert gas prevailing in the annular space, the sealing rings ensure that the leaking metal melt does not come into contact with air and therefore does not oxidize.
  • the gas pressure in the annulus is monitored by the display device. If either the upper sealing ring or the lower sealing ring should leak, an indication is given. As long as only one of the sealing rings leaks, there is still no danger that the molten metal will come into contact with air. An indication is therefore given even before a state in which both sealing rings are leaking and thus atmospheric oxygen is sucked in by the escaping melt through the seat.
  • the compressible sealing rings preferably consist of ceramic fiber material.
  • they are connected to one another by spacer webs bridging the annular space. This makes it possible to assemble both rings as a structural unit. These can be attached to the outlet or to the protective tube or the immersion spout before the protective tube or immersion spout is attached.
  • a one-piece ring component forms both rings and, if appropriate, the spacers.
  • the two sealing rings can be attached to the outlet or to the protective tube or the immersion spout before the protective tube or immersion spout is attached.
  • the lower sealing ring preferably lies against a step of the protective tube or immersion spout. This makes it easy to achieve the correct position of the sealing rings during assembly.
  • the sealing rings have a certain gas permeability. However, because of the gas overpressure of the inert gas prevailing in the annular space, this does not result in air being sucked in by the melt.
  • a different gas permeability of the compressible sealing rings results in a directed gas flow, preferably into the protective tube or the immersion spout.
  • a conical outlet stone (2) is attached to the bottom (1) of a metallurgical vessel.
  • the sealing rings (5, 6) are compressible and consist of ceramic fiber material.
  • a radial channel (9) of the immersion spout (3) opens into the annular space (7).
  • a gas line (10) for inert gas is connected to this.
  • a display device (11) for the gas pressure prevailing in the annular space (7) is located in the gas line (10).
  • the two sealing rings (5, 6) are connected to each other via spacers (12). These extend through the annular space (7) without closing it off.
  • the two sealing rings (5, 6) and the spacers (12) are made as a one-piece component from the ceramic fiber material.
  • the lower sealing ring (6) sits on a step (13) formed in the immersion spout (3).
  • the assembly consisting of the upper and lower sealing ring (5, 6) and the spacers (12) is pushed into the immersion nozzle (3) until the lower sealing ring (6) stands on the step (13).
  • the spacers (12) then lie in the area of the step (8) widening the annular space (7).
  • the immersion nozzle (3) is pushed onto the outlet stone (2) and fastened in this position in a manner known per se.
  • the fiber material of the sealing rings (5, 6) is compressed.
  • the gas line (10) can be connected.
  • the annular space (7) is charged with inert gas.
  • the pressure of the sealing rings (5, 6) and the negative pressure prevailing when casting in the immersion spout (3) a certain value arises on the display device (11), which is formed by a pressure gauge Overpressure.
