Definitions

  • the invention relates to a method for operating a converter, in which the converter is mounted by means of trunnions in a support ring on the trunnions, a transmission is cantilevered, the converter is thereby formed tiltable about its horizontal axis and the transmission by a torque arm with a foundation rigid connected is,
  • DE 38 27 329 A1 shows a torque support for riding on shaft journal drives, especially for converter rocker drives, on the driven shaft journal the gear housing is mounted, in each case to a reduction gear which engages in the rotatably mounted on the shaft journal large gear with a pinion, a drive motor is flanged or screwed, consisting from symmetrically to the axis of rotation of the driven journal on the gear housing by means of Gelenklagem mounted handlebars, the lower ends are each connected in parallel, with fixed height at floor level joint placements and are connected to each other via a rod.
  • the handlebars are formed in two parts, which are the Gelenklagem spaced opposite free ends of the handlebars connected by acting on train and pressure spring elements and the springs of the spring elements are biased by mechanical means to a predetermined value.
  • WO 03/023 072 A1 shows a converter gear, comprising a connected to the pivot axis of a converter vessel ring gear in engagement with at least one drive pinion of the converter gear, and at least one in the toothing of the ring gear or swing-out blocking device in the form of a arranged on a horizontal shaft, formed with a toothing locking arm.
  • This converter gearbox is characterized in that the shaft of the blocking arm is mounted in at least one terminal bearing and the blocking arm by force, such as hydraulic cylinders, non-positively engageable in the toothing of the ring gear, or disengaged from the engagement of the teeth and that the shaft of the blocking arm is mounted with two mutually freely rotatably mounted eccentric bushes at their shaft ends in the housing of the converter gearbox, such that by independently rotating the same a mutual ideal engagement position of the two cooperating toothing areas of the blocking device and the ring gear is adjustable.
  • force such as hydraulic cylinders, non-positively engageable in the toothing of the ring gear, or disengaged from the engagement of the teeth
  • the shaft of the blocking arm is mounted with two mutually freely rotatably mounted eccentric bushes at their shaft ends in the housing of the converter gearbox, such that by independently rotating the same a mutual ideal engagement position of the two cooperating toothing areas of the blocking device and the ring gear is adjustable.
  • DE 26 54 907 A1 shows a device on a converter with a tilting drive, which is suspended on a tilting pin of the converter, and a torque arm, which is resiliently supported on the foundation.
  • the tilting drive can be fixed against the foundation during the blowing process by means of a positioning device.
  • EP 003 108 A1 shows a torque arm for a movably mounted about a pivot axis gearbox, in particular for a converter drive, wherein the gear housing is supported against the foundation on both sides of the pivot axis with an elastic support means.
  • an elastic support means a pressurized gas pressurized piston-piston cylinder is provided whose position relative to the foundation by means of an adjusting device is adjustable.
  • DE 30 07 916 C2 shows a torque support for a riding drive, in particular for converter drives, on the driven and a large gear rotatably supporting shaft journals, the gear housing is mounted on which several the large gear driving reduction gear with respective drive motors are flanged and on the joints on opposite Side of the axis of rotation of the journal equally spaced first parallel lever are mounted, which are connected via joints with the same second, fixedly articulated parallel levers, with at least one parallel lever, one of which obliquely extending, connecting and provided with a spring coupling, all joints spherical Have joint bearing.
  • This torque support is characterized in that the second parallel levers are inclined in the normal position, that the coupling contains at least two longitudinal sections each provided with a gap and that the coupling is articulated to the joints connecting the two parallel levers.
  • a locking member of an element of a kinematic chain such as an element of a gear transmission known.
  • Such a locking member is attached, for example, to a pan of a steelworks converter.
  • the invention is therefore based on the object to provide a method by which the above-mentioned disadvantages are avoided.
  • the decisive advantage of the method according to the invention is that the converter, when the moment support is decoupled, can perform free oscillations during operation.
  • the amplitude of the free vibrations will remain limited.
  • a shock absorber is engaged.
  • the converter then executes damped oscillations.
  • the coupled shock absorber is designed to limit the maximum amplitudes of the converter during operation, but without the effect of a rigid torque support.
  • a converter 1 with trunnions 2 is shown in side view.
  • Trunnions 2 are mounted in a support ring 3. This allows tilting of the converter 1 about its horizontal axis.
  • a gear 4 is arranged to tilt the converter 1 flying.
  • the transmission 4 is connected to support the tilting moment via a torque support 5 with a foundation 6.
  • the foundation 6 is, for example, the casting platform.
  • the moment support 5 connects the transmission 4 to the foundation 6 in order to support the overturning moment.
  • the torque arm 5 is decoupled from either the transmission 4 or the foundation 6 or both, and the converter 1 is free to oscillate.
  • a shock absorber can be installed in the time of operation, by which the vibrations of the converter are damped.
