Definitions

  • AOD converters For stainless steel production mainly AOD converters are used.
  • AOD Argon Oxygen Decarburization
  • process gases argon, oxygen or even nitrogen
  • the converter refractory lining Due to the process associated with the strong dynamic Badoniaen in the converter vessel, the converter refractory lining is subject to heavy wear, so that the converter lining must be renewed at regular intervals.
  • exchangeable vessels In order to keep the converter downtimes as short as possible, it is common practice to work with exchangeable vessels. In order for the converter to be replaced, it is necessary to detach the vessel attachment from the support ring surrounding the converter and to decouple the process gas and inert gas lines.
  • a manual operating device described above is known from DE 20 51 382 A1, which describes a tiltable crucible or converter with a releasable clamping device between a support ring surrounding the converter and support pin on the converter.
  • the support pins are mounted in detachably connected to the support ring bearing bushes.
  • the bearing bushes themselves are supported on the support body by means of draw hooks, which are pivotable in and out of an engagement position, this tack hook connection being released and restored by hand.
  • the automatic fastening system basically consists of two components. On the one hand are in the support body or support ring integrated clamping means or a hydraulically actuated single-sided clamping lever, which describes a lifting cylinder via a pivoting movement. On the other hand, the respective support bracket on an integrated Gefäß Operations- and / or - fixation form, wherein the support bracket is tapered to its underside and / or outside.
  • Fig. 2 is a sectional view A-A of Fig. 1;
  • a groove-like receiving region 11 for the support brackets 10 of the converter 2 is formed on a flat upper side 20 (cf.
  • corresponding blocks 21, 22 are welded on the upper side 20 of the support ring, whose inner sides 23 extend obliquely.
  • the support bracket 10 on the converter vessel has a matched to the channel-like receiving area 11 lower console area 24.
  • This lower console area 24 is tapered downwards and in accordance with the shape of the receiving area 11 of the support ring.
