Definitions

  • the invention relates to a sliding closure according to the preamble of Claim 1.
  • a generic device in a generic device according to EP-B1-0 441 927 includes a slide lock, which is a fire-resistant top plate, a lid holding this, a fireproof slide plate and a fixed one has fireproof base plate.
  • the latter is fireproof Pouring tube connected, which by a changing device is held and pressed against this lower plate.
  • the fireproof top plate receiving cover causes a pressure via a tensioning element this top plate to the slide plate.
  • This lid is from one Screw as a locking means against moving in the direction of movement Slider plate fixed.
  • the disadvantage here is that the screws solve the usually oscillating back and forth of the slide plate can, because this slide plate vibrates like a vibration created the lid.
  • the lid cannot move vertically adjust in order to prevent thermal expansions occurring transversely to the direction of displacement or to compensate for other shifts.
  • the present invention was based on the object a sliding closure according to the type mentioned above to further develop that with a simple design, on the one hand, it is reliable Blocking of the cover in the direction of displacement of the slide plate and on the other hand perpendicular to it an at least limited adjustability is guaranteed.
  • the object is according to the characterizing part of claim 1 solved.
  • the cover is in the Operation fixed at all times and not limited to one mounting position.
  • the cover is perpendicular to the direction of adjustment of the slide plate meanwhile not rigidly attached and therefore it is capable of thermal expansion compensate.
  • a sliding closure with a pouring tube changing device on the top of the Housing arranged cover pivotally mounted on this housing and Clamping elements for pressing the closure plates against one another are in particular arranged in pairs on both sides of the lid and as on the housing swiveling clamping screws.
  • FIG. 1 shows a sliding closure 10, which is indicated at the bottom of the spout illustrated container 14 is mounted, wherein it in the case of the container, preferably around a distributor vessel of a continuous caster is.
  • a Pouring tube changing device 40 is provided, which is a refractory pouring tube 42 holds, which protrudes in particular in a continuous casting mold and a hidden one Pour the molten metal from the distribution vessel into this mold allows.
  • the sliding closure 10 has a housing which can be fastened to the container 14 12, which for this purpose on the top protruding bearing surfaces 16 has, which rest on the outer steel jacket of the container 14.
  • in the Housing 12 are an upper and a lower fixed refractory closure plate 22, 24 and one between them by a not shown Drive reciprocally movable slide plate 23 added.
  • the fixed closure plates 22, 24 are via fastening means 26 fixed in a cover 15 or in the housing 12, meanwhile, the slide plate 23 fastened in a metal frame 27 coupled to the drive is.
  • These refractory plates 22, 23, 24 each have a through opening 18, by the molten metal in the open position shown is poured out of the container 12. By a longitudinal movement this slide plate 23, the outlet can be throttled or closed.
  • This plate also serves in particular as an actuator for a regulated Pour the amount of melt out of the container 12.
  • This pouring tube 42 can be vertical shifted to the image plane via a drive, not shown and be replaced by a new pouring tube.
  • the Cover 15 is provided, which can be removed from the housing, when the slide closure 10 is removed from the container. This can after opening this cover 15, the refractory closing plates 22, 23, 24 to be replaced. This provision of the cover 15 on the top of the housing conditioned that the slide lock 10 with each change these plates are removed from the container.
  • a locking means 20 for blocking the cover 15 provided, which is designed such that it is in operation when a position change of the cover 15 in the direction of displacement of the slide plate 23 automatically locked so that the cover is always blocked, but this one Locking means 20 an occurring adjustment of the lid 15 perpendicular to Allows displacement direction.
  • the locking means 20 has two on the housing 12 by one Axis of rotation 25A mounted pivot pin 25, which on the outer jacket 25 'are formed spirally and point or preferably with the lid are in line contact. They are held on an axis 29 attached to the at least one laterally projecting pivot lever 21 is, in the locked state, a remote from the lid 15, approximately occupies a horizontal position.
  • the one from the axis of rotation 25A to the outer jacket 25 'formed radius at the respective pivot pin 25 enlarged in the opposite direction to the direction of rotation of the pivot lever 21 when locking. This will automatically tighten the Swivel pin 21 on the lid 15 by its own weight Swivel lever 21 generated.
  • the pivot pin is also cylindrical and eccentric be mounted on the axis 29.
  • this pivot lever 21 is formed with such a length that he is in the attached state of the slide closure 10 on the container 14 can not be in this open position 21 ', but in itself releases the locking position.
  • a holder 35 on the opposite one Arranged side to the locking means 20 for the drive, not shown.
  • This Bracket 35 can be pivoted away laterally on the housing via a hinge 36 12 stored.
  • Fig. 2 and Fig. 3 is another very advantageous embodiment of the sliding closure 10 according to the invention the upper refractory closure plate 22 receiving cover 15 pivotally mounted on the housing 12 and the clamping elements are in particular on both sides in pairs Cover 15 arranged and as pivotable on the housing 12 clamping screws 33 trained.
  • the latter are laterally in a recess in the cover 15 can be swiveled in and after tightening they exert tension the closing plates.
  • the cover 15 is expediently on the side
  • the pivot pin 39 of the housing 12 is mounted and its pivot axis 15A aligned in the same direction as the direction of displacement of the slide plate 23. This allows this rectangular lid to be narrow Side can be swung open.
  • On the opposite side is on the lid 15 further provided a handle 34, by means of which the lid can be opened easily.
  • the clamping screws 33 are in the area of the housing 12 mounted, which is open at the bottom and through the elongated recess 45 is formed in the pouring tube changing device, through which the pouring tube 42 with its upper plate-shaped end is feasible. These clamping screws 33 can thus easily be in the housing 12 can be installed or replaced.
  • the elongated recess 45 is therefore transverse to the direction of displacement of the slide plate 23 educated.
  • Fig. 4 and Fig. 5 show a slide closure 50, the construction corresponds to that of Figure 1 and therefore only in the different Details are explained.
  • the lid 55 is accordingly on the Arranged underside of the housing 52 and its pivot axis 55A extends transverse to the direction of displacement of the slide plate 23.
  • this sliding closure 50 is again a locking means 60 is provided, by means of which the cover 55 can be blocked.
  • This Locking means 60 is in this case fastened with two to an axis 55A Provide pivot pin 65, which in the same way as those after Fig.1 act on the cover 55.
  • the axis 55A is on two bearing eyes 52 'of the housing 52 is rotatably held and has a corresponding end Swivel lever 61, which in the locked state - as shown - approximately occupies a horizontal position.
  • the hinged cover 55 on the same axis 55A as the locking means 60 held.
  • the cover 55 has a bearing bush 55 'at the end, through which this axis 55A extends with play.
  • Steering lever 66 is provided, by means of which the cover 55 in the shown Operating state perpendicular to its longitudinal extent for the compensation of Can adjust thermal expansion or the like. This is an effective one Means for a secure locking of the cover during operation been created.
  • the invention is based on the two exemplary embodiments explained above adequately demonstrated. Of course, the invention could be constructed run differently.
