Definitions

  • the invention relates to a device for spraying a repair compound onto a perforated brick in a metallurgical vessel, which has an insertion opening for a brick, in particular a gas purging brick.
  • the object of the invention is to propose a device of the type mentioned with which the perforated brick can be repaired easily and in a targeted manner.
  • the above object is achieved in the device of the type mentioned in the introduction in that a stencil jacket, the outer contour of which corresponds to that of the stone, and a spray head are provided, which is arranged on a mass feed pipe which extends through the stencil jacket and is guided by the latter.
  • the template jacket is inserted into the hole in the perforated stone intended for the stone. He occupies the area of the stone to be used after the repair work. Repair compound is then sprayed through the spray head into the worn zone of the perforated brick in the vicinity of the stencil cover. It is advantageous for handling that the mass is supplied from the outside of the wall into which the perforated brick is inserted. There is no need for a long lance to be inserted and guided from the open side of the vessel.
  • the stencil jacket is pulled out of the insert opening together with the spray head. A new stone can now be used. There is no longer any danger that this will be sprayed with touch-up compound.
  • the spray head is fastened to the mass supply pipe and this is displaceable in the longitudinal axis direction of the template jacket and / or rotatable about the longitudinal axis. By moving the mass supply pipe, the spray head can be adjusted so that the wear areas are evenly treated with the repair compound.
  • a plate covering the interior of the stencil casing against the repair material is provided. This ensures that the repair compound does not enter the stencil jacket.
  • a perforated brick 1 has an insertion opening 2 for a conical gas purging plug, not shown.
  • the perforated brick 1 shown is worn in an area 3 in the vicinity of the insert opening 2.
  • the template jacket 4 is detachably connected to a cover part 9 by means of the screw bolts 6.
  • the cover part 9 has a neck 10 which engages in the center of the bottom 5.
  • the cover part 9 is provided with a tube piece 11, at the end of which a flap 12 is pivotally mounted on an axis 13.
  • a gas connector 14 is provided on the flap 12.
  • the flap 12 is open in the application of interest here, so that the pipe section 11 is open at its end to the environment.
  • a mass feed pipe 15 extends through the template jacket 4 and the pipe section 11 and is mounted on the guide sleeve 7 in the direction of the longitudinal axis 8 and is rotatable about the longitudinal axis 8.
  • An operating handle 16 is attached to the end of the mass supply pipe 15 lying outside the pipe section 11 (cf. FIG. 2).
  • the mass supply pipe 15 is coupled to a mass supply hose 18 via a coupling 17.
  • a cover plate 21 is attached, the diameter of which fits into the template jacket 4.
  • a collar 22 is provided on the cover plate 21. The length of which determines a working stroke H.
  • a stop ring 23 for the collar 22 is arranged on the template jacket 4.
  • the method of operation of the described device is approximately as follows:
  • the outflow direction A is directed to a wear region closest to the template jacket 4.
  • the cover plate 21 covers the interior 24 of the stencil jacket 4 against repair material.
  • the mass supply is switched off and the mass supply pipe 15 is withdrawn until the collar 22 abuts the stop ring 23.
  • the device on the pipe section 11 is pulled out of the insert opening 2, which is now ready for inserting a gas flushing plug.
  • This can be inserted, for example, into the insertion opening 2 in that the template jacket 4 with the mass supply tube 15 is separated from the cover part 9 and the gas purging plug is fixed on the cover part 9 instead. His neck 10 then engages in a gas distribution chamber of the gas purging plug. After the flap 12 has been closed, the gas purging plug can be supplied with purging gas via the gas connecting piece 14.
