Definitions
- the invention relates to a metallurgical vessel, in particular a pan for transporting molten metals, according to the preamble of claim 1.
- a metallurgical vessel is known from DE 195 38 530 C1. It consists of a single tubular tubular that holds the refractory lining
- Shots composite metal jacket which has two stiffening rings running in the circumferential direction and two vessel support pins, which are supported on the outside of the metal jacket opposite each other by a plate connected to the stiffening rings.
- the stiffening rings are an integral part of the metal jacket.
- a somewhat differently constructed metallurgical vessel is known from DE 29 05 283 B2. It is a tiltable and / or rotating steel mill converter. The converter is held by means of individual or connected support brackets attached to the vessel wall and preloading units arranged parallel and / or perpendicular to the longitudinal axis of the vessel, which establish the connection between the support brackets and a circumferential support ring provided with a plate and vessel support journal.
- a disadvantage of this construction is the need to manufacture and arrange several pretensioning units, which make the construction considerably more expensive.
- the object of the invention is to provide a metallurgical vessel, in particular a pan for the transport of molten metals, which is easier to manufacture and whose construction takes into account the different wear rates.
- the supporting structure has two supporting rings located at a parallel distance from one another, which together with the plate and the vessel supporting pins form an independent unit and are at a distance from the outside of the metal jacket and are arranged with axial play between the supporting claws.
- This constructive proposal is based on the idea that, in particular in the case of the pan, the supporting structure has the function of transferring the most varied of transport situations into the pan container without retroactive effect.
- the proposed arrangement has the advantage that the structure and the container can be separated from one another at any time and the structure can be used more frequently. It is known that the container has a limited operating life of X melts, then it must be reloaded and, if necessary, repaired. With the previously known
- Constructions cannot use the structure during redelivery and repair because it is an integral part of the container.
- the locking ring is removed and the container can be lifted out of the supporting structure forming an independent unit. Then he can z. B. turned inside out, the refractory brickwork broken out and, if necessary, the metal jacket and / or the floor can be repaired. Then it is delivered again. During this entire time, the previously used structure can be used again for a container that has already been delivered.
- Another advantage of the proposed construction is that the container can expand freely in both the circumferential and axial directions with respect to the structure.
- the proposed construction allows the realization of a thin-walled, light and nevertheless low-deformation container, which can also be manufactured extremely inexpensively and has considerable advantages for repairs
- the heat flow between the hot container and the colder structure can be reduced by arranging an insulating layer in the contact area between the structure and the claws or circlip be designed
- At least two mutually opposite claws, firmly attached to the metal jacket, are required.
- the claws can also be designed as a ring encompassing the metal jacket.
- This ring can be welded onto the metal jacket or be an integral part of the metal jacket. In the latter case, this would lead to a desired stiffening of the upper edge of the container.
- FIG. 1 shows a longitudinal section through a vessel designed according to the invention
- Fig. 2 is a view in the direction X in Figure 1 and
- Fig. 3 is a perspective view of a structure forming an independent unit.
- FIG. 1 shows a longitudinal section and FIG. 2 shows a view of an exemplary embodiment of a metallurgical vessel designed according to the invention.
- This container consists of, for example, a single pipe section or a metal jacket 1 composed of ring-shaped pipe sections, which is provided on the inside with a refractory lining 2.
- the bottom 3 is either only inserted or firmly connected to the metal jacket 1.
- the floor 3 is also provided with a refractory lining 4.
- Feet 5 are arranged on the underside of the base 3 in order to be able to deposit the container.
- the support structure 14 itself in this embodiment consists of two support rings 7, 8 and two opposing vessel support pins 9, 9 '. These vessel support pins 9, 9 'are supported on a plate 10, 10' which is arranged between the two support rings 7, 8.
- the lower support for the structure 14 forms a metal ring 1 comprising removable and mountable locking ring 11. It is essential that the structure 14 forming its own unit has a radial distance 16 to the outside 15 of the metal shell 1 and the structure 14 with axial play between the Claws 6, 6 'and the locking ring 11 is arranged.
- an insulating layer 12, 13 is provided between the claws 6, 6 'and the locking ring 11.
- the assembly is carried out in such a way that the structure 14 is mounted on a support frame and a crane inserts the container into the structure 14 from above. Then the locking ring 11 is attached so that the structure 14 can be supported on it.
- the hook loops, not shown here, are attached so that the crossbar of the casting crane above the upper edge of the container can lift it, transport it and tilt it through the hook loops. Disassembly is carried out in the reverse order.
