Definitions

  • the invention relates to a fastening for warm-running vessels, in particular for tiltable steelwork converters, the weight of which, with the approval of thermal movements when the vessel is upright, is parallel to the longitudinal axis of the vessel and, if necessary, is horizontal in the vessel position by means of transverse and perpendicular to the longitudinal axis of the vessel, in each case preloaded, flexible tensile elements which are stationary or tiltable brackets are attached.
  • Such an attachment is also applicable to interchangeable steelwork converters in which the holder is tiltably mounted in pivot pins, the holder consisting of a support frame (a closed or open support ring).
  • the object is achieved according to the invention after a first application for vertical, non-tiltable and also for tiltable warm-running vessels, in that the transverse fastening tension elements in pairs with their one ends each on a vessel holder next to the vessel and with their other ends on a displaceable hollow bearing each tensile force are attached to transmit, and that in each case a short support pin protruding into the hollow bearing is at least indirectly connected to the vessel wall.
  • this design enables heat movements of the transverse fastening in the load case «prone position and simplifies the known system of the plug pin with the plug pin receptacle. So z. B. a special ball joint, because the tension elements take over the function of the ball joint.
  • the creation of the independent hollow warehouse, which is relocatable has the effect of lowering the temperature of the most important components.
  • the hollow bearing has a square or rectangular shape on the outside.
  • cooling device located in the interior of the short support pin consists of coolant supply and coolant discharge lines running in the interior.
  • centering means are provided on the wall of the vessel and on the support frame or on the vessel holder, which are positively interlocking and are evenly distributed over the circumference.
  • the warm-going vessel 1 which from a reactor, such as. B. a nuclear reactor, another reactor, such as. B. consists of a coal gasification reactor or a metallurgical intermediate container, is shown in the drawing as a steelworks converter, in which molten pig iron is refined to steel.
  • the vessel 1 consists of the vessel wall 2, which supports the lining 3.
  • such steel mill converters can be tilted in tilting bearings 4 and 5 by means of tilting pins 6 and 7, the latter on the holder 8, which is used as a supporting frame 8a, d. H. is designed as a closed support ring are attached.
  • the tilting bearings 4 and 5 rest on the foundation 9.
  • the holder 8 does not have to be tiltable if the process running in the vessel 1 does not require such a tiltability.
  • the vessel 1 is held in the direction of the longitudinal axis 12 of the vessel by means of the flexible, prestressed tension elements 13. Upside down, i.e. H. if the steelworks converter mouth 1a points downwards, the prestress in the tension elements 13 is reduced according to the weight of the vessel.
  • transverse fastening tension elements 14a and 14b are provided (FIG. 2).
  • One end 14c is fastened to the holder 8 and the other ends 14d are fastened to the hollow bearing 15.
  • the short support pins 16 are each located on vessel projections 17, such a vessel projection 17 each consisting of upper flange plates 17a, lower flange plates 17b, which are connected to a plurality of support plates 17c, and the connection being made by welding is created (cf. in particular FIGS. 1, 4 and 5).
  • the vessel 1 according to FIG. 1 can be exchanged by loosening the tension elements 13 and placing the vessel 1 on a carriage (not shown). During the removal process, the short support pins 16 slide out of the hollow bearing 15 or are inserted into the hollow bearing 15 during the installation process. This process takes place in a position of the axis 16a of the support pin 16 parallel to the short overall h fäßstoffl Kunststoffsac se instead of 12, the example in Ouerbefest Trents-Zugomme 14a, 14b transverse soft to the vertical plane to the longitudinal axis 12 of the vessel are flexible and can therefore dodge if the short support pin 16 does not try to enter the hollow bearing 15 exactly in alignment.
  • the short support pin 16 is welded into the vessel wall 2, passes through the opening 18a and acts as an element of the longitudinal fastening in the sense of the traction elements 13 already described.
  • the hollow bearing 15 is arranged axially parallel to the axis 16a and is located within the bracket 8, d. H. in the interior of the support frame 8a. Both the short support pin 16 and the hollow bearing 15 are visible from the outside through the opening 18b and can be checked or serviced.
  • the second embodiment is not intended for a quick change of the vessel 1. However, the vessel 1 is stored here in such a way that the hollow elements 15 give in via the tension elements 13 as soon as thermal stresses occur in the vessel wall 2.
  • the short trunnion 16 can tilt and slide back and forth.
  • the tension elements 13 run through enlarged through bores 18c and 18d.
  • One of the short trunnions 16 with its axis 16a advantageously runs perpendicular to the trunnion axis of the trunnions 6 and 7 in order to transmit the tilting moment to the vessel 1.
  • FIG. 4 the first exemplary embodiment for the quickly exchangeable vessel 1 according to FIG. 1 is shown in detail on a larger scale.
  • the short support pin 16 is provided with a core hole 16b, which can be assigned several functions. One of these functions (another is described below) consists in the arrangement of the tension elements 13, which can alternatively be guided through the core bore 16b (a combination of the embodiments from FIGS. 1 and 4 is thus achieved).
  • the short support pin 16 (its effective length is determined by the minimum bending moment or the minimum stress that can be achieved in the support frame 8a and in the vessel wall 2) is inserted into the flange plate 17a with the collar 16c and rests with the flange 16d. Starting from the flange 16d, the support pin 16 has a spherical section 16e and then a conical section 16f. The spherical section 16e rests without play in the interior 15b, which is cylindrical and follows the conical entry section 15a.
  • the hollow bearing 15 itself consists of the thick-walled ring 15c, to which, in the case of an externally square or rectangular shape 15d (FIG.
  • the transverse fastening tension elements 14a and 14b are connected by means of the clamping heads 19.
  • the other ends 19a are also connected by means of such clamping heads 19 to bearings 20a and 20b on the side of the holder 8 or the holding frame 8a (support ring), a pretensioning force being transmitted to the transverse fastening pulling elements 14a or 14b in a known manner.
  • the short support pin 16 has a cooling device 22 in the interior 21.
  • the cooling device 22 according to the illustrated embodiment consists of a coolant supply line 23 and a coolant discharge line 24 with the required fittings. At the end of the coolant supply line 23, the coolant flows, such as. B. water, from an opening 25.
  • the short support pin 16 or its interior is closed by a cover 26 to the front and to the rear through the housing of the coolant discharge line 24.
