Definitions

  • the invention relates to a sliding closure on the spout of a vessel containing in particular molten metal, with at least two refractory closure parts provided with flow openings, which protrude into the interior of the vessel and have sliding surfaces therein, on which they are arranged so as to be displaceable relative to one another in a sealing manner, and the associated refractory closure parts.
  • An inflow actuator of the type described at the beginning (DE-PS 35 40 202 or EP-A-0308 597) essentially consists of two concentrically arranged, protruding into the vessel and therein tubes movable against each other with openings for melt passage.
  • the openings of the tubes can be more or less covered and thus the quantity of the melt flowing off can be regulated accordingly.
  • the two refractory pipes must be machined very precisely in the mutually contacting surface areas to achieve absolute tightness. The processing of these rotating surfaces is therefore relatively complex.
  • the risk of the pipes breaking off due to possible transverse forces occurring is relatively great.
  • the object of the present invention is to develop a sliding closure of the type mentioned in such a way that its closure parts can be manufactured more easily and therefore more cost-effectively and moreover an increased operational reliability is achieved with them.
  • closure parts within the vessel each have at least one approximately flat sliding surface on which they can be opened or opened. Closing the flow opening are displaceable sealingly against each other.
  • the flat sliding surfaces are easy to manufacture and ensure optimum operational reliability.
  • one closure part is fixed in the vessel spout and the other is arranged displaceably within the vessel.
  • One or two mutually parallel sliding surfaces can be provided for the two closure parts.
  • the closure part fixed in the vessel spout contains a recess in the vessel in which a plate for opening or closing the spout opening can be moved.
  • the invention is also very well suited for thin slab casting, in which the flow openings are slot-shaped.
  • the closure 10 shows a slide closure 10, which is arranged in the spout 13 of a vessel 12, which is only shown in a hint, for example a distributor in continuous casting plants.
  • the closure 10 consists essentially of a fixed refractory closure part 11 and a longitudinally movable refractory closure part 15 in it.
  • the sleeve-shaped part 14 of the former is embedded in the refractory vessel bottom and has a plate-shaped extension 16 which projects into the interior of the vessel and which extends in the direction of displacement of the movable part 15 has a parallel plane sliding surface 17 which is in sealing contact with a sliding surface 18 formed by a segment cutout in the movable closure part 15.
  • a flow opening 19 arranged in the plate-shaped extension 16 can be brought more or less into line with a flow opening 19 'of the part 15, which is guided in a height-adjustable manner by a drive (not shown), and the metal melt flows out of this opening 19' by moving the closure part 15. for example in a continuous casting mold.
  • the flat sliding surfaces 17, 18 of the closure parts 11, 15 can be seen again from FIG.
  • the slide closure 20 according to FIG. 3 has a fireproof closure part 23, which is mortared in a pan bottom 22 and which is only partially shown. These sliding surfaces 25, 26 are in sealing contact with sliding surfaces 27 and 28 of a U-shaped refractory closure part 24 which can be adjusted in the height direction 29 and which each has a transverse opening 32 in its legs, which - as shown - with the closure 20 open with the Cover the flow opening 33 of the fixed closure part 24.
  • FIG. 4 shows the slide closure 20 on the pan 22 and the associated drive device 35, 36.
  • the height-adjustable closure part 24 is held in a displaceable manner via a linkage 36 by a drive 35 which is held laterally on the pan 22 and forms a piston-cylinder unit.
  • the drive 35 is held on the socket 22 via a hinge joint 37 and is positioned via adjusting screws 38 for the purpose of axially parallel adjustment to the closure part 24.
  • a fireproof extension rod 31 of the closure part 24 is held on the linkage 36 by means of a bolt 43 so that it is perpendicular to the sliding surfaces 27, 28 sufficient play, however, is fixed in the direction of the sliding surfaces 27, 28, as shown in Fig.5.
  • this closure part 24 is on the one hand secured against breaking off and on the other hand positioned with respect to the fixed closure part 23.
  • the rod 31 has two stop surfaces 41 and 42 at its upper end, which enables this rod 31 to be centered in a recess 39 of the linkage 36 without play.
  • the closure part 24 could just as well be moved horizontally or in a pivoting movement to regulate the closure 20.
  • the slide closure 50 according to FIGS. 6 and 7 in turn has a refractory closure part 53 fixed in the vessel bottom 52, the flow opening 55 of which extends transversely in the interior of the vessel and vertically therefrom through an additional sleeve 56 or a pouring tube vertically from the vessel.
  • the fixed closure part 53 has a recess 57 which breaks through the transverse opening 55 and in which a refractory plate 54 is guided in a sealingly displaceable manner. By longitudinal and / or pivoting movement of this plate 54 with its transverse opening 55 ', the molten metal can be poured in a regulated manner.
  • the plate 54 also has a refractory extension 58 and can be moved similar to the closure shown in Figure 4. The rod 58 could also be led out of the pan 52 laterally or downwards.
  • the sliding closure 60 according to FIG. 8 differs from that from FIG. 3 only in that its refractory closure parts 63 and 64 are elongated and their flow openings 65 and 66 are slit-shaped.
  • the flow openings 65 of the movable closure part 64 which extend in the horizontal direction, in turn overlap in the open position with the flow opening running in transversely and passing from them in the vertical direction 66.
  • the sliding closure 60 according to FIG. 8 could be installed, for example for pouring light metal melts, with an opening 66 of the closure part 63 leading approximately horizontally from the pan. This would also result in the sliding surfaces of the two closure parts 63 and 64 lying approximately horizontally in the vessel.
