Definitions
- the invention relates to a tiltable converter, comprising a converter vessel with a vertical axis and one surrounding it at a radial distance Support ring with two support pins diametrically opposite in a horizontal axis, the load transfer between the converter vessel and support ring via Fastening elements are carried out, which together form three force components, namely longitudinal fastening, transverse fastening and transverse locking.
- the design of the known converter is characterized in that at least six pendulum rods, preferably seven pendulum rods are provided. there is in the area of each trunnion approximately parallel to that of the support ring formed plane and approximately at right angles to the tilt axis formed by the support pin of the converter vessel directed pendulum rod provided.
- pendulum bars these are approximately parallel to the longitudinal axis aligned of the converter vessel and as close as possible to the trunnion provided, preferably in an angular range of 25 to 45 degrees, wherein the angle in the plan of the converter vessel, starting from the tilt axis, is measured.
- the design of the converter is characterized in that the Bearings that have pendulum rods passing through bolts, each bolt on both sides of the pendulum rod via support straps on the converter vessel or on the support ring is supported, wherein the support tabs are preferably welded to the converter vessel and are connected to the support ring by means of a screw connection.
- a disadvantage of the known design of the tiltable converter is the large one Number of bearings at the ends of the pendulum rods, as shown in Figures 1 and 2 a total of 14 bearings, which not only have a significant manufacturing technology Effort, but also a corresponding maintenance effort cause.
- DE-C-27 39 540 relates to the prior art and DE-A-29 31 671.
- Support is provided in these known converters the converter vessel on the support ring surrounding it by means of a link, which are at least partially designed as so-called "triangular links".
- a wishbone is to be understood as one that either on the converter vessel or on the support ring with one end by means of two spaced apart spherical bearing and with its other end on the support ring or on the converter vessel is articulated with a single spherical bearing.
- the object of the invention based on a type of a tiltable converter in the preamble of claim Specify 1 type mentioned, on the one hand, a positive connection between converter vessel and support ring results, but radial as well as axial Opposes deformations of the converter vessel with the lowest possible resistance, This results in a constraint-free construction and with a favorable type of stress the other supporting elements are maintenance-free, uncomplicated and Production-technically favorable execution allows, and the fasteners form three force components together, namely longitudinal fastening, Cross mounting and locking.
- the support brackets and the spherical bearings be articulated with two pairs of push-pull rods.
- An embodiment of the load transmission converter vessel / support ring is characterized in that that the transverse lock is located at the bottom of the support ring Formation of a joint with the hinge arranged with the converter vessel a horizontal axis.
- the converter according to the invention is further characterized in that the Cross-fastening a pair of load bolts arranged on the top of the support ring comprises, which is load-supported between stops of the converter vessel are.
- the converter according to the invention is characterized in that that the cross attachment is formed with a pair of push-pull rods which is articulated below the support ring to the converter vessel, in a spherical bearing on the one hand on the support ring, and on the other hand on Converter vessel are articulated.
- the tiltable converter shown in Figures 1 and 2 with a vertical Axis x-x in a construction according to the invention comprises a converter vessel 1 and a support ring 2 surrounding this at a radial distance with two in a horizontal one Axis y-y diametrically opposite trunnions 3, 4, the Load transmission between converter vessel 1 and support ring 2 via articulated connections takes place, which together form three force components, namely longitudinal fastening, Cross fastening and cross locking, characterized in that the longitudinal fastening on the converter vessel 1 arranged below the support ring 2 Support brackets 6 and arranged on the underside of the support ring 2 at a distance Spherical bearings 7, 8, each with a triangle as a support member 9 are connectable.
- the support ring 2 and the converter vessel 1 also low degree of freedom interlocking transverse locking elements 10, 11 in Have shape of a hinge, which are designed such that they have a lateral Prevent the converter vessel 1 from tipping away relative to the support ring 2.
- the support member 9 is an approximately triangular flat material fitting, which with the support ring 2 by two spherical spherical bearings spaced apart on its circumference 7, 8, and with the converter vessel 1 by means of a respective spherical spherical bearing formed on a support bracket 6 articulated connected is.
- the converter shown in plan view in FIG. 2 comprises a converter vessel 1, surrounded at a radial distance from a support ring 2 on which a pair of support pins 3, 4 are attached in a diametrical position, the converter can be tilted about the y-y axis take up.
- Support ring 2 and converter vessel 1 are by transverse locking elements 10, 11 in Form of a hinge with the axis z-z hinged together.
- transverse forces between the converter vessel 1 and the support ring 2 due to tilting movements of the converter are additionally supported by load bolts 13 on the converter vessel 1 and these associated stops 14 on the support ring 2 to form a Lateral locking caught.
- FIGS. 3 and 5 A further embodiment according to the invention is shown in FIGS. 3 and 5 provides that the articulated connection between the support ring 2 and converter vessel 1 can also have two push-pull rods 15, 15 'which on the one hand with the support ring 2 at two spaced-apart spherical spherical bearings 7, 8, and on the other hand with a spherical bearing assigned to them at a vertical distance are articulated to a support bracket 6 of the converter vessel 1.
- Figure 4 shows an embodiment of the invention with a double arrangement of the locking elements 10, 11 opposite each other. This version has proven to be particularly robust and resilient. In contrast, the design of the Converter according to Figure 6 is particularly simple and inexpensive and is suitable for versions with a comparatively low converter weight.
