Definitions

  • the present invention relates to a closure device for the bottom pouring opening of a ladle according to the preamble of claim 1.
  • Closure devices of this type are known, for example from DE-B-1 928 400.
  • the known construction is characterized in that the slide plate is gimbally movably supported with respect to the sealing surface on the forked free end of a double link pivotably mounted on the pan base, one of the gimbal axles being supported the double-link axle lying at the forked end and extending horizontally coincides, while the second gimbal axle is defined by the vertical pivot axis of the slide.
  • This cardanic attachment enables the slide plate to pivot around two mutually perpendicular axes.
  • the present invention has for its object to provide a slide closure device based on the prior art mentioned, which is both easy to open and close and on the other hand, an automatic alignment of the slide plate is ensured such that on the The sealing surface exerts an even pressure and thus a reliable seal and even wear of the interacting surfaces of the slide and top plate can be obtained.
  • the double swivel mounting of the slide plate allows the slide lock to be opened or closed in the manner of a door or window, while at the same time ensuring that deviations from the parallel alignment between the slide and top plate are excluded.
  • the forced parallelism between the slide plate and the top plate ensures an even pressure load on the sealing surface and thus a reliable seal and even wear of the mutually associated surfaces of the slide and top plate when opening and closing the closure.
  • the slide closure can be pivoted about a longitudinal edge which is dimensioned much longer than the transverse edge, so that it does not take up too much space when the slide closure is opened.
  • a hydraulically or hydro-pneumatically actuable piston-cylinder unit is provided for closing the device, by means of which the slide plate can be brought into the operating position by overcoming a predetermined sealing prestress between the slide plate and the top plate. In this position, the slide plate is then held by a holding hook or the like.
  • the piston-cylinder unit mentioned By means of the piston-cylinder unit mentioned, the slide plate is thus pressed against the head plate under somewhat increased force, against the action of the the slide plate acting and the sealing prestress between the slide and top plate determining compression springs, so that the mechanical locking is possible by means of the holding hook mentioned. After this mechanical locking, the piston-cylinder unit is removed again, possibly only pivoted into a rest position.
  • the aforementioned piston-cylinder unit is preferably coupled to a pressure measuring and / or setting device for determining and / or setting the closing and opening pressure. It is also possible to determine excessive wear on the slide and / or head plate. Furthermore, it is possible to determine by means of the above-mentioned device whether repair slide plates are ground too thin, whether the locking mechanism is extended, whether the slide plate springs are defective, the spring sleeves are seated too deep or the like, all of which are at one Lead to impairment of the required slide plate contact pressure.
  • a closure device for the bottom pouring opening of a ladle comprises a mounting plate 10 fastened to the pan bottom, against which a head plate 13 shown in dashed lines in FIG Molten metal is located.
  • a slide plate 12 bears on the underside of the head plate 13, in which there is also a passage opening 14 for the melt.
  • the slide plate 12, which is also only shown in broken lines in FIG. 1, is inserted into a frame 15 which is arranged in a housing 16 in a plane extending perpendicularly to the central axis of the melt passage openings 11 and 14.
  • a plurality of contact springs not shown in FIG.
  • the slide plate 12 is mounted together with the frame 15 and the housing 16 between the two legs of a U-shaped housing bracket 17 pivotable about a first pivot axis 18 (see double arrow 19 in Fig. 1).
  • Said support bracket 17 is in turn mounted on the mounting plate 10 so as to be pivotable about a second pivot axis 20, the second pivot axis 20 extending through the two ends of the support bracket legs.
  • the first and second pivot axes 18 and 20 extend parallel to one another and parallel to the mounting plate 10 or sealing surface between the head and slide plate.
  • the double pivot axis mounting of the slide plate described and shown in more detail in FIG. 1 excludes deviations from the parallel alignment between the mutually corresponding surfaces of the top plate and slide plate in the operating position, ie when the ladle slide is closed.
  • the slide plate 12 adjusts itself parallel to the head plate when the device is closed, and automatically with the result that the aforementioned tension springs exert a uniform pressure on the slide plate 12. Accordingly, a permanently reliable seal is obtained between the slide plate and the top plate. The wear of the corresponding surfaces of the slide and top plate is even and therefore optimal.
  • the pivot axes 18, 20 each extend parallel to the direction of adjustment of the slide plate 12.
  • the first pivot axis 18 is preferably aligned approximately with the longitudinal axis of the slide extending in the direction of adjustment of the slide plate 12.

  • the pivot axis of the holding hook 22 is identified by the reference number 23.
  • the ladle is brought into a position in which the pivot axes 18, 20 extend approximately vertically. In this way, little space is required to open the slide arrangement.
  • the bracket 17 velvet Housing 16 and slide plate 12 is opened in the manner of a relatively narrow door.
  • the device mentioned is indicated in FIG. 2 with the reference number 25.
  • This device can be used to determine whether the contact pressure between the slide and top plate is still sufficient. Furthermore, it can be determined whether the springs biasing the slide plate in the operating position are defective.
  • this pressure measuring and / or setting device 25 can also be used to determine whether the slide plates have been ground too thinly during the repair, so that insufficient contact pressure between the slide plate and the top plate is guaranteed during operation. It can also be determined in this way whether the slide mechanism is extended or whether the preload spring sleeves are too deep.
  • the described locking device with the pressure measuring and / or setting device 25 represents an extremely valuable aid.
  • the slide plate 12 is conventionally driven by a hydraulically actuated piston-cylinder unit, i.e. slide back and forth to set the desired degree of opening of the ladle pouring spout.
