Definitions

  • the invention relates to a vessel for the metallurgical treatment of pig iron, steel melts u.
  • a converter vessel which is supported on a spaced-apart support ring which is tiltable by means of tilting pin in both sides Kipplagem, over the circumference of the vessel wall distributed claws rest on the upper flange of the support ring and wherein the support on the upper flange of the support ring means additional fastening means is detachably formed.
  • claws fasteners such as. Clamping screws, hinged screws and pincer mechanisms with appropriate operation, all of which have the stated disadvantages and are very difficult to handle and their handling takes too much time. Due to the operational heating of the vessels also occur thermal expansions in the individual components that complicate the release of the fasteners. In addition, there is also the fact that the release and change process must be carried out at the increased ambient temperatures by the operator from close range. In the relatively tight accessibility loosening of clamping nuts with appropriate tool is quite power consuming.
  • the invention has for its object to provide a fast, easy and manageable at a sufficient distance means that does not have the disadvantages mentioned.
  • the support on the upper flange of the support ring consists of each opposite vessel brackets and support ring brackets, which by means of a snap closure in a closed direction to a secure closed position with each other braced and easily detachable in an opposite direction of actuation are.
  • an actuating element In the closed state, an actuating element is moved beyond the so-called dead center and can be brought into a self-locking and lock-secure position.
  • the distributed on the circumference brackets can be arranged symmetrically or asymmetrically depending on Tragringform and serve as points of attack for such a quick-fastening device.
  • the resulting lever system is adapted to the clamping distances and ensures the secure hold of the vessel even in tilting positions.
  • the snap closure can also be easily and safely pressed into the closed position or the release position with a manually attached hydraulic handling device. Consequently, the same auxiliary device can be used for opening. It is first moved out of the dead center until the open position is reached.
  • the snap closure consists of a vessel console encompassing clamping bracket which is pivotally mounted on an actuating lever, wherein the actuating lever with its upper End is pivotally mounted rotatably on the support ring console.
  • This design is further developed so that in the closing direction of the clamping bracket surrounds the vessel console and rests against the outer peripheral surface of the support ring and that the actuating lever is latched with locking bolts, which are arranged on both sides of the clamping bracket.
  • the pushing back of the actuating lever to the support ring causes a pivoting away from the support ring and releases the vessel console for removal of the vessel.
  • Such an actuating mechanism saves the usual underlay elements with a spherical seat and the corresponding handling of the components. For the operator, only a small amount of force and relatively short time access to the quick-change attachment system is required.
  • the release of the vessel can be achieved in a simple manner, that during an opening movement of the actuating lever from the peripheral surface of the support ring to the outside of the clamping bracket on the vessel console is pivotable into an open position.
  • the arrangement is made such that the vessel console in the side profile forms a lower recess in which the support ring console with clear space fits. This consumes very little space.
  • the number of vessel brackets and support ring brackets may vary depending on the shape of the support ring (whether full or partial ring).
  • the flap closure can be arranged on the top flange, outside or at a distance between the support ring and the vessel.
  • a second alternative embodiment is that the vessel console consists of a single, correspondingly thick sized console plate.
  • the support ring console consists of a single, appropriately sized console plate.
  • the associated lever systems are designed according to a development in such a way that the clamping bracket consists of two spaced, parallel clamping straps which are connected at their ends by means of a transverse, spacer element, or are rotatably connected to spaced support ring-Konsolplatten, wherein in a central , thick support ring console, the spacer element lever tabs for the actuating lever receives and forms the pivot bearing.
  • the actuating lever consists of two spaced, parallel lever tabs which, forming the pivot bearing, are connected by means of transverse spacer elements.
  • a clamping element is formed of a running between the spaced, parallel vessel brackets or between spaced support ring console plates tension lever rod with a resting on this hammer head, which is connected to the, connecting the two lever brackets pivot bearing and between two support ring console plates runs.
  • the vessel console encompasses an oval, closed clamping bracket forms.
  • a vessel 1 which, for example, consists of a converter vessel 1a, is used for the metallurgical treatment of melts, for example the refining of pig iron or steel melts.
  • the vessel 1 is supported at a distance 2 on a support ring 3 by means of over the circumference of the vessel wall 1 b distributed claws 6 and between these or these associated supports 4.
  • These supports 4 consist of additional fasteners.
  • the claws 6 lie, open at the top, laterally between guide walls 5 a, which respectively constitute vessel guides 5.
  • Each support 4 consists (Fig. 1) on the upper flange 3a of the support ring 3 each of an opposing vessel console 7 and a support ring console 8, by means of a closer to be described snap closure 9 in a closing direction 10 to a secure closed position 11 are clamped together and easily detachable in an opposite direction of actuation 12.
  • the clamping bracket 13 moves during the opening movement in the opposite direction of actuation 12 and back to the closed position 11 on the vessel console 7 away, with the actuating lever 14 only from the outer peripheral surface 3 c of the support ring 3 away ( Fig. 3) and then this again approaches (Fig. 4). As a result, the open position 16 is reached.
  • the vessel console 7 forms a lower recess 7b in the side profile 7a, in which the support ring console 8 with space between them finds space.
  • FIGS. 5 to 8 various alternatives for the vessel console 7, the support ring console 8 and the clamping bracket 13 are shown.
  • the vessel console 7 consists of two console plates 17 arranged laterally at a fixed distance 7c.
  • the vessel console 7 consists of a single, correspondingly thickly dimensioned console plate 18.
  • the support ring console 8 is made analogous to a single, correspondingly thick sized console plate 19.
  • the tensioning bow 13 (FIGS. 5 and 7) is formed from two spaced, parallel tensioning straps 13a and 13, which are connected at their ends 13b by means of a transverse spacer element 20.
  • a pivot bearing 22 may be provided for rotation of the tension bracket 13 relative to the actuating lever 14.
  • the lever tabs 21 receives for the actuating lever 14, provided for a pivot bearing 22.
  • the actuating lever 14 is formed in each case from two spaced, parallel lever tabs 21 which receive the pivot bearing 22 and the lever tabs 21 are connected by means of the transverse spacer elements 20.
  • FIGS. 6 and 7 Other alternative embodiments include FIGS. 6 and 7 with respect to the embodiment of the tension bow 13.
  • a tension bow 13 is in the form of a tensioning element 23 of a between the spaced, parallel vessel brackets 7 or between spaced support ring console plates 8a extending clamping lever rod 24 formed with a resting on this hammer head 25.
  • the tension lever rod 24 is itself connected to the pivot bearing 22 connecting the two lever tabs 21 and extends between two support ring console plates 8a.
  • the tension lever rod 24 extends between two support ring console plates 8a and forms a vessel console 7 embracing, oval shaped, closed clamping bracket 26th
