Definitions
- the invention relates to a tiltable converter with a pendulum rods comprehensive suspension system.
- Converters of this type are known, for example, from DE4327640 and from US6228320.
- the pendulum rods are connected in each case with one end to the converter vessel and with the other end on the support ring on all sides articulated by means of spherical pendulum rod depositors.
- the spherical Pendelstablager have as bearing pins on the pendulum rods passing through bolts, the bolts on both sides via support tabs on
- Support tab bearings are arranged, are covered on their side facing away from the pendulum rod of covers that prevent contamination and the
- pendulum rods which are connected in each case with one end to the converter vessel and with the other end on the support ring on all sides articulated by means of spherical pendulum rod depositors,
- At least one stabilizing device for limiting a movement of the converter vessel relative to the support ring
- Covers are not sufficiently designed for conventional loads according to DE4327640 and US6228320 for the actual loads occurring.
- the pendulum support and support tab bearings are due to
- Support tab bearings existing press fits the components of the pendulum rod storage and support plate bearings, so that components of pendulum rod and support tab bearings can move each other. These relative movements lead to the stress on the covers, which is expressed in deformation and tearing of the covers from their attachments. Since the forces in the direction of the longitudinal axis of the bolt in known converters with pendulum rods comprehensive suspension systems on the support plate bearings in the covers, both covers and support plate bearings are over burdened and threatened by damage. By the solution according to the invention forces are introduced in the direction of the longitudinal axis of the bolt under reduced load of the support plate bearings in the covers. The clamping screw fixes the covers and the between the
- the clamping screw is designed for a multiple of the maximum loads of the covers. Forces in the direction of the longitudinal axis of the bolt are distributed by the central clamping screw on both covers.
- the converter is used, for example, for steel production.
- the bolt forms the bearing pin of the pendulum rod bearing or the support plate bearing.
- Pendelstablager formatieri extending both with respect to the Pendelstablager as well as with respect to the support tab bearings are positively, and arranged between the spherical support tab bearings and the covers supporting tab bearing intermediate elements which are positively against both the support tab bearing and against the cover.
- An embodiment of a tiltable converter according to the invention in which the support plate bearings each have a bearing inner ring formed by a ball portion is characterized in that the Stauerlaschenlager fundamentallement is a ball ring with a cover facing the ball surface which is positively applied to a spherical surface portion of the cover,
- the different spherical surfaces thus come from different spheres, whereby the spatial position of the centers of these spheres is the same for all spheres.
- the spherical pendulum rod bearing on a bearing outer ring, and the bearing outer ring of the spherical Pendelstablagers is fixed by means of a holding device on the pendulum rod, wherein
- At least two stop devices for limiting the rotational latitude of the associated pendulum rod are mounted about its longitudinal axis.
- the stop devices for limiting the rotational latitude can be any suitable stop devices.
- stop blocks which are preferably made of metal.
- the stop devices are mounted so as to cover the region of the holding device and / or the pendulum rod which lies in a plane perpendicular to the longitudinal axis of the pendulum rod and containing the longitudinal axis of the bolt.
- the bearing outer ring of the spherical Pendelstablagers is fixed by means of a holding device on the pendulum rod, wherein the holding device relative to the
- Pendelstablager basicettivothylcholine sealing ring wherein the lamellar sealing ring rests on one of the holding device opposite curved spherical surface of Pendelstablager fundamental institute.
- Figure 1 shows an overall view of a tiltable converter with a suspension system comprising pendulum rods.
- FIG. 2 shows an enlargement of the area bordered by a dashed line in FIG. 1 in section.
- FIG. 3 shows an enlarged detail from the representation of FIG. 2.
- Figure 4a shows a side view of a pendulum rod located between a pair of support tabs.
- Figure 4b shows a rotated by 90 ° view of the arrangement shown in Figure 4a. Description of the embodiments
- a converter vessel 1 is connected to a support ring 2 via a suspension system.
- the suspension system comprises several pendulum rods 3.
- the pendulum rods 3 are connected at one end to the converter vessel 1 and at one end to the support ring 2 via support tabs 4.
- the pendulum rods are connected to the converter vessel 1 and the support ring 2 on all sides articulated by means of spherical Pendelstablager, which are not shown for clarity.
- FIG. 2 shows an enlargement of the area framed in broken lines in FIG. 1, showing the spherical pendulum rod bearing and the spherical one
- Bolt 7 passes through the pendulum rod 3.
- the pendulum rod 3 is mounted on the bolt 7 spatially pivotable.
- the bolt 7 is supported on both sides of the pendulum rod 3 via support tabs 4 on the converter vessel 1.
- the bolt 7 passes through openings in the support tabs 4 and is mounted spherically in the support tabs 4.
- the openings in the support tabs 4 are covered on the side facing away from the pendulum rod 3 side of covers 8.
- the bolt 7 is penetrated in the longitudinal direction by a clamping screw 9, which also covers 8 of the bolt 7 supporting pair of
- Support tabs 4 interspersed. Between the covers 8 of the pair of support tabs 4 is a positive connection, which extends over the spherical pendulum rod bearing and the spherical support tab bearing.
- Figure 3 shows an enlarged detail of the illustration of Figure 2.
- the positive connection between the covers 8 of the pair of support tabs 4 of Figure 2 - of which for clarity in Figure 3 only one is shown - runs through bearing bush 10, and bearing inner ring 1 1st a the spherical pendulum rod bearing or bearing inner rings 1 1 b the spherical support plate bearings, as well as arranged between the spherical pendulum rod bearing and the spherical support tab bearings Pendelstablager demandieri 12, both with respect to the
- Bearing bush 10 and the bearing inner ring 1 1 a of the spherical pendulum rod storage as well relative to the bearing inner ring 1 1 b of the spherical support tab bearing are positively, and arranged between the spherical support tab bearings and the covers 8 Stauerlaschenlager fundamental phenomenon 13, both with respect to the
- the bearing outer ring 14 of the spherical Pendelstablagers is by means of a
- Holding device 15 is attached to the pendulum rod 3.
- the holding device 15 is sealed relative to the pendulum rod intermediate storage elements 12 by means of a laminar sealing ring 16, wherein the laminar sealing ring 16 rests on one of the holding device 15 convex spherical surface of the pendulum rod intermediate storage elements 12.
- the Stauerlaschenlager fundamentallement 13 is a ball ring with a cover 8 facing the ball surface which is positively applied to a spherical surface portion of the cover 8, wherein the radii of
- FIG. 4a shows a side view of a pendulum rod 3 located between a pair of support tabs 4.
- Two stop blocks 17 are mounted on the holding device 15 as stop devices for limiting the rotational freedom of the pendulum rod 3 about its longitudinal axis.
- the stop blocks 17 are mounted on the holding device 15. They are positioned there so that they limit a rotation about the longitudinal axis of the pendulum rod.
- Figure 4b shows a rotated by 90 ° view of the arrangement shown in Figure 4a.
- a plane containing the longitudinal axis of the pendulum rod 18 is shown in phantom running vertically.
- the stop block 17 covers the region of the holding device 15, which is located in a dash-dot horizontally extending plane 19, which is perpendicular to the plane containing the longitudinal axis of the pendulum rod 18 and contains the longitudinal axis of the bolt. In this way, a rotation of the
- Pendulum rod 3 limited to its longitudinal axis. The limitation is made by stop Since the abutment block is slightly higher than the screws 20 securing the retainer to the pendulum rod, these screws 20 are protected from damage by the abutment block in the event of rotation of the pendulum rod 3 about its longitudinal axis.
