Problems solved by technology
The possibility of damage to the back-up bearings increases due to this damage making the cover ineffective and due to the limited ability of the cover to hold its position in place
Repairing said damage is labor-intensive and reduces the availability of the steel-producing converters

Embodiment Construction
[0038] exist figure 1 Among them, the converter shell 1 is connected with the bearing ring 2 through a suspension system. The suspension system includes a plurality of swing rods 3 . One end of the swing rod 3 is connected to the converter shell 1 through a support bracket 4 , and the other end is connected to the bearing ring 2 . Here, the pendulum is articulated on all sides to the converter shell 1 and the carrier ring 2 by means of spherical pendulum bearings, which are not shown for better visual clarity.
[0039] The stabilizing device consists of a pair of guide claws 5a, 5b fixed on the carrier ring 2 and a stabilizer 6 fixed on the converter shell 1, which limits the mutual movement of the converter shell 1 and the carrier ring 2.
[0040] figure 2 In the enlarged cross-sectional view is shown figure 1 The area enclosed by the dotted line in , and shows the spherical rocker bearing and the spherical stent bearing. The pin 7 passes through the fork 3 . The rocke...

The invention relates to a tiltable converter having a suspension system comprising pendulum bars (3) which are each connected by one end on the converter vessel (1) and by the other end on the bearing ring (2) by means of spherical pendulum bar bearings, articulated on all sides. According to the invention, the spherical pendulum bar bearings have bolts (7) passing through the pendulum bars (3) on which the pendulum bars (3) are spatially mounted in a pivoting manner, wherein each bolt (7) is supported on both sides of the pendulum bar (3) via support brackets (4) on the converter vessel (1) or on the bearer ring (2) and the bolts (7) are mounted in the support brackets (4) by means of spherical support bracket bearings. The openings of the support brackets (4), through which the bolts (7) pass through and in which the spherical support bracket bearings are arranged, are covered by covers (8) on the sides thereof facing away from the pendulum bar (3). The converter according to the invention is characterized in that, for at least one of the pendulum bars (3) and the parts of the suspension system allocated thereto, the bolt (7) is passed through in the longitudinal direction by a tensioning screw (9) and the tensioning screw (9) passes through the covers (8) of the pair of support brackets (4) supporting the bolt (7), and there is a form-fitting connection between the covers (8) of the pair of support brackets (4) which runs over the spherical pendulum bar bearing and the spherical support bracket bearing.
Description
technical field [0001] The invention relates to a tiltable converter with a suspension system comprising a rocker. Background technique [0002] Such converters are known, for example, from DE4327640 and US6228320. The swing rods are connected to the converter shell at one end and connected to the carrier ring at the other end by means of spherical swing rod bearings in an articulated manner around the periphery. As the bearing pin, the spherical rocker bearing has a pin extending through the rocker, wherein the pin is supported on both sides by means of brackets on the converter shell or on the carrier ring. The pin is supported in the support by means of a spherical support bearing. In this case, the opening through which the pin penetrates in the bearing (in which the spherical bearing is arranged) is covered on its side facing away from the rocker by a cover which is intended to prevent contamination and to preserve the position of the bearing . A problem that can ar...
