Definitions

  • the invention relates to a slide closure for a container containing molten metal, with a housing part which can be fastened to this and a slide unit which can be longitudinally displaced relative to it and in each of which a refractory slide plate can be inserted, the slide unit being held in a longitudinally displaceable manner by a plurality of holding means attached to the housing part perpendicular to it.
  • Sliding closures of this type are known to be used in continuous casting systems for opening and closing the pouring opening of a metallurgical vessel.
  • the molten steel causes high temperatures, which are also transferred to the valve body in the vicinity of the refractory valve plates.
  • the temperatures are much lower, roughly close to room temperature in the surrounding area.
  • the slide housing must nevertheless also be stable in this area for the attachment of the holding means for the slide unit.
  • a slide fastener of the type mentioned is in the document EP-A-1 119 428 disclosed, in which the housing part extends in the displacement direction over the entire length and laterally to outside of the holding means, so that these holding means are placed in the area between the slide plates and the longitudinal walls of the housing part.
  • the holding means fastened in the housing part are connected to one another on both sides of the closure plates by means of a connecting rod. This has the effect that the slide unit can only be released from the housing part when it can be moved into this position, which is outside the open and closed positions, in which the spring members are then relaxed.
  • the invention is based on the object of avoiding these disadvantages and of creating a sliding lock of the type mentioned at the beginning, which can also be opened in the event of a malfunction, in particular when the sliding unit can no longer be moved.
  • the housing part should not be susceptible to cracking and should at the same time be stable enough in terms of strength so that the holding means that hold the slide unit on it are properly supported.
  • the housing part of the slide fastener very advantageously has walls running in the longitudinal direction relatively close to the slide plates with lateral extensions which are provided with bearings for the individual holding means of the slide unit.
  • the required rigidity of the housing is nevertheless sufficient for the secure storage of the holding means for the slide unit in the eye-shaped bearings of the housing and an improved plate support that remains straight is thereby achieved.
  • the invention also provides that the housing part has two lateral extensions on each side, the bearings of which are arranged in the housing part symmetrically to the pouring opening of the slide closure. This symmetrical arrangement enables the holding means to be optimally transmitted to the slide unit and thus to the slide plates of the closure that are to be pressed against one another.
  • the invention further provides that the holding means are provided with sliding rollers sliding on guide tracks of the slide unit parallel to the working plane of the slide lock, which are acted upon against the guide tracks by spring elements arranged in the bearings. In this way, any deformations of the eye-shaped bearings are compensated without affecting the guidance of the slide unit along its guideways.
  • the holding means In terms of a simple construction of the holding means, it is expedient if they have a bolt-shaped connecting member guided in their bearings and a carrier for at least one sliding roller, preferably detachably connected to it.
  • the eye-shaped bearings are designed as bearing bushes and these attachments receiving them have a bushing diameter that is adapted to the bushing diameter semicircular end part, preferably in the form of a half-shell which closes off the approach at the end face.
  • the invention also provides that the slide unit is hinged to the housing part by means of a hinge connection, the hinge wings of which are attached on the one hand to the slide unit and on the other hand directly to one longitudinal wall of the housing part. As a result, the hinge wings are securely attached to the housing part.
  • the slide lock 10 according to Fig. 1 or. Fig. 2 is suitable as a closure member in a pouring ladle (not shown in detail) or a similar container containing molten metal, such as are used in particular in continuous casting plants for steel. Of course it is also suitable as a locking device, for example for foundries in the non-ferrous metal sector.
  • This sliding closure 10 consists essentially of a housing part 1 and a sliding unit 2 which is longitudinally displaceable in relation to this and which is articulated on the longitudinal side of the housing part 1 with a hinge connection 3.
  • an upper refractory base plate 4 is fastened, to which a lower refractory slide plate 5 of the slide unit 2 is pressed in the closed state, the latter being held in a longitudinally displaceable manner by several holding means 6a, 6b and 7a, 7b fastened perpendicular to it on the housing part 1.
  • the normally cast housing part 1 has outer walls 8, 9 running in the longitudinal direction relatively close to the plates 4, 5 with lateral extensions 10a, 10b and 11a, 11b, which preferably have eye-shaped bearings 12 for the individual holding means 6a, 6b and 7a, 7b of the slide unit 2 are provided.
  • These side walls 8, 9 of the housing part 1 are each dimensioned at a distance of approximately one to several centimeters from the outer sides of the plates 4, 5 so that this housing part has an approximately uniform temperature distribution in the operating state during casting.
  • the holding means 6a, 6b and 7a, 7b are in turn provided parallel to the working plane of the sliding lock 10 with sliding rollers 14 sliding on guide tracks 13a, 13b of the slider unit 2, which against the guide tracks 13a, 13b by spring elements built into the bearings 12 15 are acted upon.
  • These guideways 13a, 13b are in turn divided in the conventional manner by an opening 34 each for releasing a respective sliding roller 14 and provided at the end with ramps 33 in order to be able to tension or relax the holding means and with them the spring members, as described in the publication EP-A-1 119 428 is explained in detail.
  • the bearings 12 of the holding means 6a, 6b, 7a, 7b are designed as bearing bushes, the lugs 10a, 10b; 11a, 11b are provided with a semicircular end part adapted to the bushing diameter in the form of a half-shell that closes off the neck at the end.
  • the housing part 1 has two lateral extensions 10a, 10b or 11a, 11b on both sides, the bearings 12 of which are placed in the housing part 1 symmetrically to the pouring opening 16 of the slide closure 10.
  • This arrangement enables optimal power transmission from the holding means 6a, 6b; 7a, 7b onto the slide unit 2 and thus onto the plates 4, 5 which are pressed against one another in the closed state.
  • the individual holding means 6a, 6b; 7a, 7b consist of a bolt-shaped connecting member 17 guided in the bearings 12 and a carrier 18, detachably connected to it to facilitate assembly, for the sliding roller mounted thereon.
  • the carrier 18 can be provided on both sides with sliding rollers running along their own guide tracks. Instead of sliding rollers, sliding blocks and similar sliding elements can also be used.
  • these holding means 6a, 6b; 7a, 7b individually detachably fastened to the housing part 1 in such a way that they can be released from the housing part in almost any position of the slide unit 2 in the clamped state of the slide lock 10. This is particularly important in the event of a malfunction, when the slide unit can no longer be moved primarily in the event of a breakthrough due to welded molten steel.
  • Fig. 3 shows the slide unit 2 released from the housing part 1 according to the invention.
  • the bearings 12 of the holding means 6a, 6b; 7a, 7b are each removed in the manner of a bayonet by rotating the housing part 1 perpendicular to the latter.
  • the bearings 12 and with them the holding means 6a, 6b; 7a, 7b are each rotated by a certain angle, with the sliding rollers 14 connected to them also being pivoted, which lie against the guide tracks 13a, 13b of the slide unit 2.
  • the holding means 6a, 6b; 7a, 7b with the bearings 12 can then be removed from the slide unit 2 and, as the case may be, fastened again in the housing part 1.
  • the bearings 12 of the holding means 6a, 6b; 7a, 7b each with longitudinal guides 12 'running uniformly over the circumference on their outer side, which are each like a bayonet in corresponding grooves 10 ", 11" of an opening 10', 11 'in the approach 10a, 10b and 11a, 11b of the Housing part 1 can be inserted and then secured therein by twisting and fixing by means of a locking means 26.
  • These openings 10 ', 11' are here with a provided cylindrical part in which a respective bearing 12 can be rotated and positioned.
  • Fig. 4 shows the one extension 10a of the housing part 1 and the bearing 12 of a holding means fixed therein by the locking means 26.
  • the bearing 12 is rotated in the respective opening 10 ', 11' until its longitudinal guides 12 'rest over those of the openings 10', 11 '.
  • FIG. 5 the position of the bearing 12 with the locking means 26 removed and the rotated position in the opening 10 ', 11' illustrated, in which the bearing 12 with its longitudinal guides 12 'can be displaced through the grooves 10 "and removed from the housing part 1.
  • the inner wall of the opening 10 ', 11' are each associated with corresponding longitudinal guides 27 to those of the bearing 12, between which the grooves 10 ′′ run.
  • Fastening screws not shown, which can be swiveled into corner tabs 19 of housing part 1 and then tightened against them, are used to fasten the sliding closure to the pouring ladle.
  • a drive element likewise not illustrated, in the form of a hydraulic cylinder, the push rod of which can be connected to a coupling claw 20 of the slide unit.
  • the slide unit 2 is articulated in a manner known per se on the housing part 1 by means of the hinge connection 3, the hinge wings 21, 22 are fastened on the one hand to the slide unit 2 and on the other hand directly to the one longitudinal wall 9 of the housing part 1.
  • the construction according to the invention of the housing part 1 is also suitable for a sliding lock, the holding means 7a, 7b; 8a, 8b are designed differently than described above, insofar as they also have a storage of the holding means in the lugs 10a, 10b; 11a 11b of the slide unit 2 is possible.
  • the invention is sufficiently demonstrated with the illustrated embodiment. However, it could also be clarified by other variants. So it could also be a three-plate slide lock, in which a slide plate would be arranged in a conventional manner in an additional frame between the housing part and the slide unit. The housing part would then be in the same way as in the variant after Fig. 1 designed with the advantages according to the invention, the slide unit then being guided displaceably solely for the purpose of automatically tensioning the closure.
  • the holding means could be detachably attached to the housing part in a manner other than bayonet-like, for example by a type of screw connection or a snap coupling or the like.
