Definitions
- the invention relates to a converter, in particular for the refining of pig iron, with a tiltable converter vessel and a supporting ring mounted in a trunnion, which is arranged at a distance from the converter vessel, a rectangular Has cross-section with a top flange and a lower flange and the above vascular guides and connected via lamellae with the converter vessel is, where a lamella suspension consists of a pair of lamella, the via a first mounting bracket with the lower flange and a second mounting bracket is connected to the converter vessel and wherein a vessel guide from two, preferably attached to the upper belt guide walls exists for a between these in the circumferential direction backlash guided guide piece, which is connected via a third mounting bracket to the converter.
- the mounting brackets are insoluble with the support ring or the Converter vessel welded.
- the slat suspensions can be overflowing Slag or in case of vascular damage caused by leaking steel or damaged by falling caking from the exhaust stack or even destroyed become.
- a repair or renovation can only by mechanical separation of the damaged units and their replacement by new units become.
- the object is achieved in that the connections between the pairs of lamellae and the first and second mounting brackets and between the Guide pieces and the third mounting brackets as releasable force and form-locking clamping element connections are formed.
- This acts it is a kind of flange connection between the consoles and the guide piece or the pair of slats, in the loads by interposition of conical clamping pieces are transmitted.
- clamping element connections a Have screw ring and a clamping ring the associated Clamping surfaces by conical clamping pieces by means of clamping screws are fixed. Since the screws themselves only small clamping forces To transfer is a simple release of the Clamping element connection and thus a lighter exchange possibly damaged elements without the previously required complicated mechanical separation possible.
- An advantageous embodiment of the invention continues in that at least the first mounting consoles with the Clamping rings or firmly connected to the screw rings. Both alternative layers of the screw rings provide a good one Accessibility of the clamping screws and thus facilitate the Exchange of the lamellae pairs.
- the Arrangement of the clamping element connection parallel to the Pair of lamellae has the advantage that the light diameter of the Tragrings to expand the converter vessel smaller than the alternative arrangement.
- the alternative has Arrangement the advantage of a favorable introduction of forces of the pair of lamellae in the support ring.
- Figure 1 shows a section through a part of a tiltable Converter vessel 1 with a support ring 2, this with Distance surrounds and not shown trunnions is tiltable.
- the support ring 2 has a rectangular cross-section with a top chord 3 and a bottom chord 4. He is over a total of eight lamellae suspensions - the four packages in the respective segment portion of the trunnions are arranged - connected to the converter vessel 1.
- the lamellae 5 serve to accommodate the weight the converter vessel 1 in its vertical position and Belly days, while the vessel guides 6 in its tilted Position (prone) proportionate support forces transferred. Both allow in any position an unhindered thermal expansion of the Converter vessel 1 in the axial and radial directions.
- a lamella suspension 5 consists of a pair of lamellae 7, via a first attachment bracket 8 with the lower flange. 4 of the support ring 2 and a second mounting bracket 9 with is connected to the converter vessel 1.
- first and the second attachment bracket 8, 9 and the two ends of the Lamellae pair 7 clamping element connections 10 are arranged. These consist of a respective screw ring 11 and a Clamping ring 12, the associated clamping surfaces 13, 13 'through conical clamping pieces 14 fixed by means of clamping screws 15 are, whereby the screw rings 11 and the clamping rings 12th be detachably connected.
- the screw rings 11 have a bottom 16, with which the Ends of the pair of slats 7 connected via shear connectors and are bolted.
- the screws are only for holding together in the axial direction via a respective shim 17 on the Ends of the pair of lamellae 7, wherein the tensile forces of Lamellae pair 7 on Scherbüchsen 18 on the floors 16 of Transfer screw rings 11. Transfer the screws yourself no loads.
- the clamping rings 12 of the support ring near the end of the plate pairs. 7 are with the first mounting bracket 8, the clamping rings 12th the support ring far end of the pair of slats 7 with the second Fixing bracket 9 firmly connected.
- the first Mounting bracket 8 consists of an extended Bottom plate 19, with the clamping ring 12 and the lower flange. 4 and with two attached to the lower flange 4 side walls 20th is firmly connected.
- the second attachment bracket 9 is tubular and as Extension of the clamping ring 12 is formed. This form represents unlike the usual rectangular cross sections of the CONSOLE CONSULTING a force application without Voltage peaks in the converter vessel 1 safely. This is the risk of cracking in the converter vessel 1 in the area of Mounting brackets 8, 9 largely banned.
- the vessel guide 6 consists of two guide walls 21, the Upper belt 3 are fixed and a play between and with distance to the top flange 3 guided guide piece 22, the via a third mounting bracket 23 with the converter vessel 1 is connected. Between the guide piece 22 and the third Mounting bracket 23 is again a Clamping element connection 10 with a screw ring 11 and a Clamping ring 12 is arranged. The bottom 16 of the screw ring 11th and the guide piece 22 and the clamping ring 12 and as its extension trained tubular third Mounting bracket 23 are firmly connected.
- Figure 2 shows a plan view of a LameLLenaufhfitung 5, with the plate pair 7, the shims 17 with holes for the Scherbüchsen 18, the extended bottom plate 19 and the both side walls 20 of the first mounting bracket 8, the all three are attached to the lower flange 4. Also the second Mounting bracket 9 and the bottom 16 can be seen.
- FIGs 3 and 4 are alternative embodiments and Arrangements of the clamping element connection 10 of the first Mounting bracket 8 shown.
- Fig. 3 shows a reverse arrangement of the clamping element connection 10.
- the Screw ring 11 is with its correspondingly adapted bottom 16 attached to the first mounting bracket 8.
- Of the Clamping ring 12 is with its extended bottom plate 19 with the Support ring near the end of the pair of slats 7 connected. Also at This arrangement is the solubility of the clamping element connection 10 guaranteed, but with a better accessibility the fixing screws of the upper clamping element.
- the clamping element connection 10 is in one position shown parallel to the lower flange 4 of the support ring 2.
- the Clamping ring 12 has a tubular extension 24 which is connected to the lower flange 4 of the support ring 2.
- Across from the position parallel to the pair of slats 7 ( Figures 1 - 3) is here according to the second and third tubular Mounting bracket 9, 23 a force introduction without Voltage peaks in the lower flange 4 of the support ring 2 given.
- a sub-console 25 for Recording of the support ring at the end of the pair of lamellae 7 attached.
- Between the slats of the pair of slats 7 is a provided small distance. This prevents one Slat wear due to their relative movement during strain-induced bending of the same. Furthermore he ensures the unimpeded freedom of movement Load-related movements of the same.
- the arranged on the mounting brackets 8, 9, 23 Clamping element connections 10 allow a simple Replacement of individual slat suspensions 5 and Vascular guides 6 and the lifting of the converter vessel. 1 without mechanical cutting.
