while this is pivoted up and down.

The invention is therefore to provide a holder or a suspension for pneumatically-actuated, metallurgical container through which the container in "is kept its vertical and inclined or tilted positions, and {tap comprising a differential expansion between the container and a surrounding Kipp Furthermore, according to the invention, a suspension for a converter container is to be created in which the mechanical load is distributed relatively uniformly around the tilting ring and in which an axial expansion of the container is not limited or restricted.

According to the invention, this is the case with a suspension for a tiltable, metallurgical container according to the preamble of Claim 1 solved by the features in the characterizing part of claim 1. Advantageous further developments of the subject of the application are listed in the subclaims.

According to the invention there is thus a container for processing of molten or molten metal on a toggle (pin) ring held by a number of triangular parts and adjustable ble intermediate or connecting links. Any triangular Part is pivotably connected to the container via a clamping ring which rests on the upper tilting ring flange. The intermediate or connecting links are pivotally connected to the container and to a second clamping ring, which rests on the lower tilting ring flange. A number Woodruff is between the second clamp ring and the Tilt (pin) ring arranged.

Preferred embodiments of the invention are set out below described in detail with reference to the drawings. Show it:

"Λ:

see pivot or pivot pin ring 16 surrounded (the following for the sake of simplicity is referred to as a tilting ring.) From each of the diametrically opposite sides of the tilting ring 16 are a pair of coaxial pivot or pivot pins 17 before, of which only one is shown in Figure 1. The pins 17 are generally in corresponding, not shown Mounts stored and are connected to a corresponding drive mechanism, also not shown, which creates the torque required to tilt the tilt ring 16 and the container 10 which it carries and holds. The pivot pins 17 can also be hollow so that cooling water can be passed through the interior of the pivot ring 16. In the Embodiments shown is the interior of the tilting ring water cooled, although the details of execution are omitted as they are well known and do not form part of the invention form.

The tilting ring 16 shown in FIGS. 1 and 2 has an upper one annular flange 20 and a similar lower flange 21, which at a certain distance from the upper flange 20 and is arranged generally concentrically and parallel to this. The flanges 20 and 21 are on their edges connected by an annular, inner end plate 22 and by an annular, outer end plate 23, which is arranged concentrically to the end plate 22 at a certain distance parallel to this. The connections between the flanges 20 and 21 and the end plates 22 and 23 can in a corresponding manner, for example by welding, be created and secured. The tilting ring 16 in the illustrated Embodiment is essentially a hollow, circular one (in cross section) rectangular beam. Although it is not shown in detail, the rocker ring 16 can inside be reinforced by a series of circumferentially spaced, radially extending plates, which each have, if necessary, an opening for circulating cooling water. It goes without saying that the container.

suspension can be used regardless of whether the tilting ring 16 has a shape shown in Fig.1 and 2 or whether it is in another form, for example as an I- or U-beam or is also present in any other cross-sectional shape.

The container 10 is attached to the tilt ring 16 by an upper hanger 26 and held by a lower suspension device 28. The upper hanger 26 has a Clamping ring 30 abutting upper flange 20 and a number of generally triangular connecting links 32 which are pivotally connected at their lower ends to the ring 30 and at their upper ends to the container 10. The ring 30 is coradial to the upper flange 20 and may be a single piece or a number of arcuate pieces Segments exist. In cross-section, the ring 30 is generally L-shaped with its long leg 34 above the upper flange 20 is arranged and runs parallel to this. The leg 34 of the ring 30 can be directly on the Flange 20 rest, or a thin metallic shock absorber pad 36 can be arranged between them. The shorter one Leg 38 of the clamping ring 30 runs behind the inner edge of the flange 20 downwards.

Each link 32 has a relatively thick base portion 40 which tapers to a thin neck portion 42. The base part 40 of each link 32 is pivotally supported between two upright support arms 44 which are attached to the upper surface of the clamping ring 32 at a predetermined distance from one another. A pivot pin 46 extends through aligned bores 48 in the support arms 44 and through a hole 50 extending through the base 40 the neck part 44 and aligned openings 56 in support arms 58, which run parallel and in a front

030008/0779

given distance from each other are attached to a ring 60, which is attached to the jacket 12 above the toggle ring 16. The bores 50 and 5 4 in each link 32 are accurate parallel to each other so that the connecting links are simultaneously at their upper and lower ends with respect to the clamping ring 30 and the container shell 12 can be pivoted. Each of the bolts 46 and 52 can be threaded at one end be provided so that they are held in a certain position, for example by means of screw nuts 62.

The lower suspension device 28 has a second clamping ring 64, which is designed similarly to the upper clamping ring 30 is, and a number of links 65 on. The long leg 66 of the ring 64 is parallel to the lower flange 21 and a number of disc springs 68 provided at certain intervals are arranged between them. The short Leg 70 of ring 64 also hooks behind the lower inner edge of the flange 21. ·

Each of the connecting members 65 has a pair of eye bolts, each having a head portion 74 with a continuous Bore 76 and a threaded shaft 78 have. In an internally threaded sleeve 80 is each of the shafts 78 are screwed so that the distance between the bores 76 and consequently the length of each link 65 can be set. The lower end of each link 65 is secured by a bolt 81 between two support arms 82 pivotally mounted, which are attached to a second ring 84 at a distance from one another and parallel to one another, which is generally mounted under the toggle ring 16. the Screw bolts 81 extend through bores 76 and through mutually aligned bores 86 in the support arms 82. The upper end of each link 6 5 is similarly by means of bolts 88 between a second pair pivotally supported by support arms 89 which are attached to the lower surface of the clamping ring 64. Screw bolt 88 lapsed

030008/0779

fen between holes 92 in the support arms 88 and through holes 76 in the upper ends of the connecting links 65. The Screw bolts 81 and 88 are arranged parallel to one another so as to allow the connecting links to pivot at the same time 65 at their opposite ends, and they are each threaded at one end, on which screw nuts 94 are screwed.

Although the support arms 58 and 82 shown in FIG Having the same height as their respective rings 16 and 84, they may be of greater height for reinforcement have and have parts not shown, which abut against the surface of the shell 12 and attached to it are.

In a preferred embodiment shown in FIG of the invention, all upper links 32 are arranged so that their correspondingly wider base parts 40 on the upper clamping ring 30 are attached and their correspondingly smaller neck parts 42 are pivotably connected to the ring 60 are. In a further embodiment of the invention shown in FIG. 6, every second connecting link 32 'is reversed, so that their base parts 40 are pivotably attached to the ring 60, while their smaller neck parts 42 are pivotable are attached to the clamping ring 30.

There are a number of connecting links 32 of the upper suspension device 26 and a number of connecting links 65 the lower suspension device 28 is provided, which is arranged around the container 10 at certain distances from one another and all pivotable in the manner described with reference to FIGS. 2 to 4 with the container shell 12 and the corresponding upper and lower clamping rings 30 and 64 are connected. This results in a different radial expansion of the container 10 and the tilting ring 16 allows, as the connecting members 32 and 65 freely at their opposite ends

-Sf-

which can be pivoted. If, for example, the container 10 should expand more in the radial direction than the tilting ring 16, as a result of which the jacket moves to the right with respect to the tilting ring 16, as can be seen from FIG the connecting member 32 is pivoted clockwise about the bolts 52 and 56, while the connecting member 65 counter to the Would pivot clockwise about the bolts 81 and 88. Similar pivotal movement in links 32 and 65 takes place when the container is longitudinally due to temperature differences and internal stresses during of the operation should increase. In addition, the links 32 do not only support the container when it is in a vertical position Location is located, but the connecting members 32 and 65 also form the holder for the container, if this is in various intermediate tilt positions and when it is pivoted up and down.

The clamping rings 30 and 64 take on a radial load on the part of the connecting members 32 and 65, so a radial Reduce stress in the tilting ring flanges 20 and 21 to a minimum. In addition, the clamping rings 30 and distribute 64 the compressive stresses on the tilting ring relatively evenly when the container is arranged vertically. Further the links 32 and 65 prevent lateral displacement of the container while pivoting up and down. This is particularly indicated by the upper connecting links 32 improved, which resist lateral deflection due to their approximately triangular design. The spring washers 68 between the lower clamping ring 64 and the tilting ring 16 enable a relative movement between the clamping ring 64 and the rocker ring 16 so that the links under the rocker ring are also used for carrying and holding during the tilting and also when the container is reversed. Consequently, support arms are used in the conventional systems are not required to hold and carry the container while turning. In addition, the

030008/0779

adjustable of the connecting links 65 changes in length, the have become necessary due to changes in the container dimensions during operation.
