Description

The invention relates to a tiltable hot-running vessel, in particular a steelworks converter, the vessel map of which · '*! one or two claw rings for connection to a supporting ring surrounding it at a distance or instead has claws distributed over the circumference of the vessel, for the support in the Prone position of the vessel resilient or elastic support means between the claw ring or claws and support ring are provided.

To compensate for the axial and radial expansion differences between the vessel jacket and the It is known to support ring, long expansion screws or similar stretchable clamping elements for the connection to use the clamp rings on the vessel side or clamps with the support ring. Here it is for a secure hold of the vessel in its prone position is necessary.

apart from the clamping elements parallel to the longitudinal axis of the vessel, such elements also exist in the plane radial to the vessel Provide expansion screws in such a way that they are as perpendicular as possible in the prone position of the vessel. this requires that the tensioning elements lying in the plane radial to the vessel are in or very close to that through the longitudinal axis of the vessel and the plane going along the tilt axis are to be arranged.

However, this arrangement is often not possible due to a lack of space. Such cases occur especially then on. if in the case of converters that are already in operation as a result of the differences in thermal expansion Type of fastening of the vessel that does not compensate or not sufficiently compensate for its claw rings or claws are torn and now after applying new claw rings the vessel by means of elastically stretchable Clamping elements should be attached. Because the distance between the tilting bearings is not increased can fit the described plat / gripping tensioning elements not in the / wipe tilting device and Gcfjß remaining narrow space (cf. / for example the versions according to DTPS I 583 245 and DT-OS 1 533 909).

From DT-OS 1 458 843 a type of fastening for retinal vessels is known, which also absorbs the differences in expansion elastically, also in / around Vessel can be arranged in a radial plane, but not necessarily / between vessel and tilting device must be provided. These radial support means are arched on the claw rings Pan plates adjacent piston or support heads formed, which are on the support ring via a Support the disc spring package and / or a hydraulic or pneumatic power device in a resilient manner. These The design of the radial support means is too expensive and expensive because of their large number of kinematic elements prone to failure.

The invention is based on the object of such To find a place of construction for the support means, which are particularly effective in the prone position of the vessel, so that they can be used as much as possible Simplicity of the components the radial and axial expansion differences between the vessel and Take up the support ring elastically. In addition, it is required that the support means also to the side of the tilt axis plane can be arranged so that they can e.g. B. arranged after tragic even with converters that have been in operation whose space / wipe vessel and tilt drive are not sufficient for the accommodation would.

To achieve this object, the invention is used for a tiltable vessel of the type described at the outset proposed for its support in its prone position in the tilt axis plane or in a to this parallel plane with the claw ring or the correspondingly arranged claws firmly connected to provide peg-shaped support bodies which each rest on an abutment in a plane radial to the vessel, which consists of a support frame rigidly connected to the support ring and a loose perforated plate that runs parallel to the support frame on the other side of the Slützzapfens and means to both sides with Distance to this arranged stretchable tensioning means is elastically connected to the support frame.

This is an extremely simple design for the safe elastic support of the vessel found in its prone position. The support pins can vary depending on the space available be provided in the tilting plane or offset on one side to this. Of course is with

the same effect the kinematically reversed arrangement the proppant possible, thus covered by the invention is included. In this case, the support pins are fixed to the support ring and the support brackets are rigid connected to the claw rings or claws of the vessel.

Preferably, two support pins are arranged symmetrically to the axis of symmetry of the vessel for each claw ring and an additional one in the axis of symmetry. The vessel and the support ring are loosely coupled to one another Centering device provided. This prevents the vessel from being repeatedly heated and cooling could gradually migrate from the exact central location.

The stretchable clamping means that connect the loose yoke plate to the support frame are expedient from bundles of individual wires, the ends of which are combined in a manner known per se at anchor heads and which can be pre-tensioned by means of a screw nut or the like. This elastic tension ensures that that the friction between the Stüizzapfen on the one hand and the support frame and the perforated plate on the other hand remains relatively narrow.

The support pins preferably have an elongated, round or rectangular cross-section, with dit load-bearing end faces in the case of a rectangular peg cross-section with a cylindrical shape parallel to the longitudinal axis of the vessel Axis or similar are arched.

Finally, it is proposed that the yoke plate to be dimensioned and / or shaped so that it acts as a leaf spring. This creates an additional elasticity of the Support reached. For this purpose, it is expedient for the surface of the yoke plate facing the support pin to be in an untensioned position Condition slightly cylindrical arched to such an extent that this yoke surface with normal The tension of the tensioning elements is flat. This leaves the possibility unhindered that the support pins to be able to move relative to the Slützböcken and Jochplattcn without constraints and with little friction.

In the drawing, two embodiments of the invention are shown, namely shows

F i g. I schematically a converter, vertically according to the line l-l in FIG. 2 cut.

F i g. 2 the same converter in the prone position and cut along the line H-II in FIG

F i g. 3 has the same cross-section as FIG. 2 in the case of a converter with one-sided offset to the tilt axis Represents support elements;

F i g. 4 shows the support elements on a larger scale namely in the prone position of the vessel and along the line IV-IV in FIG. 5 while cut in

F i g. 5 shows the same support elements in section along the line V-V in FIG. 4 are shown.

With the converter vessel 3, which can be tilted about the tilting axis 1 in bearings 2, an upper claw ring 4 and a lower claw ring 5 firmly connected. These claw rings 4, 5 are stretchable in a manner known per se Longitudinal tensioning elements 6 so braced with the support ring 7 that the converter vessel 3 radially and can expand axially practically free of constraints.

For transverse fastening of the vessel 3 for its prone position are on each of the two end faces of the support ring 7 with two support brackets 8 lying parallel to the tilt axis i Support surface 9 welded on, the height of the support brackets 8 being slightly smaller than the axial gap is dimensioned between the end face of the support ring 7 and the claw ring 4 and 5, respectively. On the support surfaces 9 are support pins IO, which with the support ring 7 facing end face of the claw ring 4 and 5 are welded. The one formed by Stütz.bock 8 Abutment is supplemented by a yoke plate 11, which is braced with the support frame 8 by means of tensionable expansion bolts 12. The expansion bolts 12 consist in itself known manner from individual wires 13, the ends of which heads on Ankei 14, 15 are combined. The yoke-side Anchor head 15 is provided with an external thread for a clamping nut 16. Mount around the expansion bolts 12 Both the trestles 8 and the yoke plates 11 are each with two lateral slots 17 which are closed by means of locking plates 18 after the expansion bolts 12 have been installed.

In the embodiment of Figure 4 and 5 have the Support pin 10 rectangular cross-section, wherein the bearing surfaces are approximately cylindrically flat arched with an axis parallel to the longitudinal axis of the vessel. If the expansion of the claw ring 4 resp. 5 and the support ring 7, the support pins 10 can move to one side or the other, wherein the frictional forces that occur are low. So that the vessel with the shifting of the support pin 10 cannot migrate on one side to the symmetry axis of the support ring 7, is a loose centering coupling are provided, the coupling parts 19, 20 of which can be hidden from one another and one of the coupling parts 19 on the claw ring 4 and the other coupling part 20 on the support ring 7 is fixed.

Like F i g. 2 and 3 show that the elastic transverse fastening can not only be used in the plane of the tilt axis but can also be arranged offset on one side to this. The new elastic and only very simple components The type of fastening required is therefore also applicable to converters where z. B. because of one The tilt drive arranged near the vessel does not have sufficient space in the tilt axis plane stands.
