Definitions

  • the invention is based on a slide closure according to the preamble of claim 1.
  • the object of the present invention is to create a slide which ensures a secure closure of the metallurgical vessel closure of the type described. This object is achieved with a slide closure with the features set out in claim 1.
  • the contact pressure is not applied at many points distributed over the entire length of the pressure rail, but rather only at one point, with the counter-arching of the guideway of the slide plate in connection with the free, rocker-like mounting of the pressure rail arranged on one in the central plane of the flow hole Axis is caused that the pressure force only at one point respectively.
  • Line acts on the plates. In this way, even larger manufacturing tolerances or differences in thickness resulting from working up used plates are compensated for without intervention in the system and without a loss of closing force.
  • the curvature can be arranged outside the center of the plate, in particular in cases where only plates with a through-flow bore are used, while the culmination point of the curvature is expediently in the median plane of the plates when using a mixed set of plates made of closed plates and plates with a flow bore .
  • the slide closure for the pouring of metallurgical casting vessels 1 has a vessel-fixed closure plate 2 and three slide plates 3A, 38, 3c one behind the other in the direction of thrust, made of heat-resistant material, each with a through-bore 6 respectively. 7 are provided for the Sctuielze.
  • the slide plates 3 are each axially displaceably guided on guideways 8 in resiliently mounted pressure rails 10 in such a way that the plates 2, 3 slide on one another with their mutually facing closure surfaces and the flow bores 6, 7 can be brought into cover and out of cover, so that the flow hole 6 of the closure plate is covered by a closed area in front of or behind the slide plate, as seen in the pushing direction.
  • a mixed plate set can also be provided, of which one or two plates are closed as closure plates, while correspondingly only one plate or two plates have a flow hole 7.
  • the pressure rails 10 are each freely held in the manner of a seesaw on an axis 11 which extends transversely to the center line M1 of the flow hole 6 of the closure plate 2 and in a bearing 13 ent is spring loaded against the direction of pressure.
  • the pressure rail 10 is held on the axle 11 mounted in the manner of a two-armed lever and acted on at its free end by means of a spring 9, but the axle itself can also consist of resilient material and at its free end be firmly clamped so that their spring action is based on their material properties.
  • the guideways 8 of the slide plate 3 each have a curvature directed against the pressure rail 10, the culmination line of which, in the embodiment shown in the drawing, lies in the central plane of the flow bore 7 of the slide plate 3, but for the purpose of increasing the contact pressure in the area of the closure surface the slide plate 3 can also be arranged outside the central plane of the flow bore 7.
  • the effective pressure length of the pressure rails 10 is greater than the distance measured in the thrust direction between the culmination points of the guideways of two slide plates lying one behind the other, but smaller than the distance between the outer culmination points of three plates lying one behind the other. In the case of the use of a set of plates made of plates with a centrally located culmination point of the guideways, this corresponds at least to the length of one slide plate and a maximum of the total length of two slide plates 3 lying one behind the other be extended by chamfered insertion zones 12.
  • the closure according to the invention works as follows:
  • the plates are moved together to the left to cover the holes 6 and 7, whereby on the one hand the path culmination point of the plate 3C reaches the area of the effective length of the pressure rail 10 and at the same time resp. immediately before this time the path culmination point of the plate 3A emerges from the effective length while the path culmination point of the plate 3B continues to pass the axis 11 and thus from the right side to the left side of the Seesaw overruns. This ensures that the effective plate 3B is loaded with the maximum force in the closing direction and the pressure rail is kept in balance without forming a bridge between the outer plates 3A and 3C.
  • the three-plate slide closure for metallurgical shown in FIGS. 3 to 6 has, in addition to the vessel-fixed closure plate 21 and the slide plate 22, a further stationary plate 23 which is arranged in a carrier 24 and is held against the slide plate 22 by means of a clamping frame 25.
  • the clamping frame is fastened on the one hand directly to the slide housing 28 by means of a joint 26, 27 and on the other hand held against the slide plate 22 by means of a retaining bracket 29, which is also articulated on the slide housing 28 and has a clamping screw 30.
  • a strip 32 is provided on both sides of the flow bore 31, which forms a - the culmination point of a curvature - transverse bearing for the stenter, so that the stenter and the carrier just support each other on a straight line and the clamping force applied is evenly distributed over the entire plate.
  • One-sided canting - in the longitudinal direction of the closure - is therefore reliably excluded.
  • the joint for the tenter frame is formed by an axis 26 and a joint sleeve 27 surrounding it, which as a bearing for the axis 26 has a bore that widens out in a truncated cone-like manner on both sides from the central plane.
  • the stationary plate is thus mounted in an oscillating manner in its two relevant levels, a rocker in the longitudinal direction being formed over the bar 32 and a rocker in the direction perpendicular to the bearing 26, 27 with the effect that, taking into account the unavoidable thickness tolerances or otherwise unevenness an absolutely even distribution of the holding force over the entire surface of the plate and thus an absolute tightness are ensured.
  • the tensioning frame 25 is formed by a profile frame and the culmination line is formed by a profile strip fastened to the carrier 24, but it can also be formed by a curved or tapering roof, a flow hole for the melt, or in another suitable manner .
