Definitions

  • the invention relates to a sleeve arrangement for blowing gases or solids into a pan containing molten metal, e.g. in the area of a sliding closure, the sleeve of which essentially has the shape of a truncated cone provided with a flow channel and which is to be inserted into a perforated brick of the pan wall with a conical opening.
  • the object of the present invention is therefore to propose a sleeve arrangement of the type mentioned at the outset in which a faster setting and replacement of the sleeve can be achieved with great accuracy of the sleeve seat.
  • the conical outer surface of the sleeve and the conical inner surface of the opening of the perforated brick have a corresponding slope for self-locking fit, preferably of 5 and that the conical inner surface of the opening of the perforated brick is lined with a sheet metal jacket of low material thickness of the same pitch is. This ensures a quick and clean, since mortar-free changing in the relatively hot state with a precise fit of each subsequent sleeve with great security and with little cleaning effort.
  • a good and firm connection of the sheet metal jacket to the perforated brick can be guaranteed in that the sheet metal jacket is permanently fixed in the opening of the perforated brick with a mortar having a low sintering temperature.
  • the sheet metal jacket has a material thickness in the range between 0.6 and 1 mm, preferably around 0.8 mm, an extraordinarily precise fit of the sleeve is ensured while normal tolerance deviations of the perforated brick are compensated for.
  • the sheet metal jacket should be made with a tolerance of about 0.1 mm.
  • An adapter for a pull-out device at the outer end of the sleeve means that the sleeve can be changed quickly and cleanly.
  • the single figure illustrates in vertical section an embodiment of a sleeve arrangement having the invention.
  • the sleeve arrangement 1 consists essentially of a sleeve 2 and a perforated brick 6.
  • the sleeve 2 has a flow channel 7 concentric with the central longitudinal axis for blowing in gases or solids.
  • the sleeve 2 is frustoconical on the outside.
  • An opening 8 of the perforated brick 6, into which the sleeve 2 is to be inserted, is correspondingly conical.
  • the conical lateral surface 9 of the sleeve 2 and the conical inner surface of the opening 8 of the perforated brick 6 have a slope of exactly or essentially 5 °, the tapered part of the sleeve 2 pointing towards the interior of the molten metal pan, the wall of the perforated brick 6 being a component .
  • a sheet metal jacket 4 of low material thickness is inserted into the opening 8.
  • the sheet metal jacket 4 has the same slope or conicity as the inner surface 10 of the opening 8 of the perforated brick 6 and the lateral surface 9 of the sleeve 2.
  • the sheet metal jacket 4 is permanently fixed in the opening of the perforated brick 6 with a mortar 3 of low sintering temperature.
  • the latter has an adapter 5 on the end face of its expanded outer end for the engagement of a pull-out device.
  • the adapter 5 is arranged concentrically to the flow channel 7 in the case shown and delimits part of the same.
  • the insertion and extraction movement of the sleeve 2 is illustrated in the drawing with a double arrow.
