Definitions
- the invention relates to a clamping device for a ceramic closure plate in a support frame or a cassette of a closure, in particular one Slider closure on a metallurgical vessel, with a between the Sealing plate and the support frame or the cassette arranged, the Closure plate surrounding and holding tape.
- the closure plate is by means of individual elastic Profile pieces held on the support frame. These are in between the Closure plate and the support frame extending gap provided where this runs in a straight line; in the curved area of the gap or Closure plate, the closure plate is not clamped. The Clamping is uneven in relation to the circumference of the closure plate.
- the above object is achieved in that the band in the longitudinal direction is corrugated, the closure plate facing wave hump on resilient these rest and the bumps facing the support frame or the cassette also resiliently rest against this or this.
- the band extends around the circumference of the closure plate. His Wave bumps alternately press against the closure plate in a resilient manner and against the support frame or the cassette. This makes the locking plate along its entire circumference evenly in the support frame or the cassette clamped. Any tolerances of the locking plate and the support frame or the cassette, are due to the spring elasticity of the corrugated tape balanced.
- the invention further provides that between the support frame or the Cassette and the shutter plate inserted corrugated tape opposite is compressed in its free state.
- To compress the tape preferably between the support frame or the cassette facing wave humps and the support frame or the cassette Intermediate plate arranged.
- the longitudinally corrugated band 4 forms wave bumps 7, which to the Closure plate 1 are pressed and between these respective bumps 8, which are supported by intermediate plates 9 in the support frame 2.
- both the wave bumps 7 and also the wave bumps 8 are provided with flattenings.
- the embodiment according to FIG. 2 has the advantage that the flattenings 10 are only at the closure plate 1 are provided, that is, none of their compressive strength particularly high demands are to be made, and due to the rounded Wave hump 8 on the support frame 2 still a dense sequence of Wave bumps 7, 8 is possible.
- Wave bumps 7 and wave bumps 8 are both in the straight line Circumferential areas 11 as well as in the curved ones Circumferential areas 12 are provided.
- the closure plate 1 is thereby their entire circumference clamped evenly in the support frame 2.
- the intermediate plates 9 are both in the straight peripheral regions 11 and also provided in the curved peripheral regions 12. Instead of A plurality of intermediate plates 9 can also be a single intermediate plate use.
- the corrugated band 4 is inserted into the gap 3 in the relaxed state in which the wave bumps 7, 8 are at a distance H (see FIG. 4), the distance H being approximately equal to the gap width B.
- the intermediate plates 9 are then pressed in between the shaft bumps 8 and the support frame 2 in the direction of the arrow E (see FIG. 3).
- the intermediate plates 9 are provided with bevels 13 and the support frame 2 with an associated bevel 14.
- the intermediate plates have the thickness d.
- the distance H is 5 mm, for example, and is compressed to 3 mm with an intermediate plate 2 mm thick.
- By upsetting the corrugated band 4 exerts the desired clamping force on the closure plate 1.
- a force of 100 kg / cm can be transmitted to the closure plate 1 with a corrugated band in which a wave hump of length l, where l is approximately 1 cm.
