Definitions

  • the invention relates to a refractory unit for a sliding closure at the spout of a molten metal containing container, with a usable at the container nozzle refractory adapter stone, an adjoining refractory bottom plate to which a sliding refractory slide plate is connected, which allows opening or closing of the sliding closure, wherein adjacent to the adapter plate adjoining the first bottom plate, a second bottom plate adjacent, which is inserted for a change of the first bottom plate below the adapter stone.
  • Slide closures on the spout of containers for molten metal are known in various designs.
  • a sliding closure, which is used in particular for opening and closing a converter spout opening, is disclosed, for example, in EP 0 819 488 B1.
  • a housing frame in which a stationary refractory closure plate (a so-called bottom plate) and one of these opposite sliding, held in a slide unit refractory slide plate are arranged.
  • the slide plate is sealingly pressed with its upper sliding surface to a lower sliding surface of the bottom plate.
  • the housing frame is detachably mounted on a container-fixed base plate, wherein the bottom plate is clamped on its upper sliding surface with a refractory spout head used in the base plate.
  • the refractory parts are exposed to heavy wear. It is therefore necessary to exchange them relatively frequently. For this, the housing frame must be detached from the base plate in each case.
  • the present invention has for its object to provide a refractory unit for a sliding closure on the spout of a container for molten metal, in particular a converter, in which the exchangeability of the refractory floor panels of this unit can be done safely and easily
  • the replacement of the floor panels can be carried out easily when the slide fastener is mounted.
  • FIG. 1 shows a sliding closure in cross-section, with a present in a starting position, two bottom plates containing cassette.
  • Fig. 2 shows the sliding closure of Fig. 5 in cross section, with the cassette in an end position.
  • a sliding closure 1 according to FIG. 1 is preferably arranged on the spout of a converter, of which only a base plate 32 carrying the sliding closure 1 is visible, in which a refractory adapter block 21 is mounted.
  • the sliding closure 1 has a housing frame 30 with a cassette 40 in which a refractory bottom plate 10 and a likewise refractory second bottom plate 12 are inserted.
  • a slide unit 20 is further arranged with a refractory slide plate 18 and an adjoining refractory spout 19. For the opening or closing of the sliding closure 1, the slider unit 20 is moved together with the slide plate 18 and the spout sleeve 19 located below this perpendicular to the image plane, which is not illustrated in detail.
  • the one base plate 10 can be removed by moving the cartridge 40 by means of a drive provided for example as a cylinder unit 34 from the operating position and replaced by the other closure plate 12 without the housing frame 30 must be dismantled.
  • a drive provided for example as a cylinder unit 34 from the operating position and replaced by the other closure plate 12 without the housing frame 30 must be dismantled.
  • FIG. 2 shows the refractory unit 5 for the sliding closure 1, which is provided with a refractory adapter block 21 which can be inserted into the container nozzle.
  • a refractory adapter block 21 which can be inserted into the container nozzle.
  • the refractory base plate 10 to which the displaceable refractory slide plate 18 and the spout sleeve 19 can be connected.
  • first bottom plate 10 adjoins a second bottom plate 12 at.
  • the two bottom plates 10, 12 are advantageously formed identically with their outer dimensions, wherein the first bottom plate 1 is aligned with its opening concentric with that of the adapter block 21.
  • the adapter stone 21 in the direction of the second base plate 12 has a length such that it is in sliding contact with this second base plate 12 with its lower sliding surface 21 '.
  • the adapter stone 21 is in sliding contact with this second bottom plate 12 at least over a length of a few millimeters.
  • the adapter block 21 has a round outer shape and is accordingly segment-shaped on the upper sliding surface 12 'of the second base plate 12. It is provided with a chamfer 29 at its lower sliding surface 21 ', at least in the region with this second base plate 12. Such a bevel 29 is also advantageously provided opposite if the bottom plate 10 were inserted from the other side.
  • the refractory parts of this refractory unit 5 are each surrounded by at least one zirconium insert or the like and a surrounding refractory mass.
  • each of the outer circumference forming metal cassettes are present.
  • the bottom plate or the slide plate are each assigned an all-round graduation 10 ", 12", 18 ', which enable an approximately clearance-free insertion of the same into the housing frame 30 or into the slide unit 20.

Abstract

L'invention concerne une unité réfractaire destinée à un obturateur à tiroir situé sur la busette de coulée d'un contenant pour métal en fusion. Cette unité réfractaire comporte une pierre réfractaire formant adaptateur (21) pouvant être installée sur la busette de coulée, et une plaque de fond réfractaire (10) adjacente audit adaptateur, une plaque coulissante réfractaire mobile (18) pouvant être reliée à la plaque de fond (10). La plaque réfractaire mobile (18) permet d'ouvrir ou de fermer l'obturateur à tiroir (1). Une seconde plaque de fond (12) est contiguë à la première plaque de fond (10) qui est adjacente à l'adaptateur (21). La seconde plaque de fond (12) peut être insérée sous l'adaptateur (21) en vue du remplacement de la première plaque de fond. L'adaptateur (21) présente, dans la direction de la seconde plaque de fond (12), une longueur telle que la surface lisse inférieure dudit adaptateur (21) est en contact glissant avec la seconde plaque de fond (12).
