Definitions

  • Vessel for the metallurgical treatment of pig iron, steel melts and. Like., In particular converter vessel
  • the invention relates to a vessel for the metallurgical treatment of pig iron, steel melts and.
  • a vessel for the metallurgical treatment of pig iron, steel melts and.
  • a converter vessel which is supported on a spaced support ring, which can be tilted by means of pivot pins in tilting bearings on both sides, the support ring resting on the upper flange by means of clawing the vessel wall and the support on the upper flange of the support ring being detachable using additional fastening means is trained.
  • the basis is formed by the fastening elements, such as clamping screws, hinged screws and pliers mechanisms with corresponding actuation, which all have the stated disadvantages and are very difficult to handle and take too long to handle. Due to the operational heating of the vessels, heat expansions in the individual components, which make it difficult to loosen the fastening elements. In addition, the loosening and changing process at the elevated ambient temperatures must be carried out by the operating personnel at close range. Given the relatively restricted accessibility, loosening the clamping nuts with the appropriate tools is quite time-consuming.
  • the object of the invention is to propose a means which can be handled quickly, easily and at a sufficient distance and which does not have the disadvantages mentioned.
  • the support on the upper flange of the support ring consists of mutually opposing vessel brackets and support ring brackets, which can be clamped together in a closing direction up to a secured closed position and in an opposite actuation direction by means of a snap lock are easy to solve.
  • an actuating element In the closed state, an actuating element is moved past the so-called dead center and can be brought into a self-locking and locking-secure position.
  • the brackets distributed around the circumference can be arranged symmetrically or asymmetrically, depending on the shape of the support ring, and serve as points of attack for such a quick fastening device.
  • the resulting lever system is matched to the clamping distances and ensures that the vessel is held securely even in the tilted position.
  • the hinged lock can still be easily and safely pressed into the closed position or the release position using a manually operated hydraulic handling device.
  • the same auxiliary device can therefore be attached for opening. It is first moved out of the dead center position until the open position is reached.
  • the flip-top closure consists of a tensioning bracket encompassing the vessel console, which is pivotally mounted on an actuating lever, the actuating lever with its upper one End is pivotally mounted on the support ring bracket. This also means that there is little effort per attachment point.
  • the release of the vessel can be achieved in a simple manner in that, during an opening movement of the actuating lever, the tensioning bracket can be pivoted outward from the peripheral surface of the support ring via the vessel console to an open position.
  • the arrangement is such that the vessel console forms a lower recess in the side profile, in which the support ring console is located at a clear distance. This means that very little space is used.
  • the number of vessel brackets and support ring brackets can depend on the shape of the support ring (whether full ring or partial ring).
  • the flap closure can be arranged on the top flange, on the outside or at a distance between the support ring and the vessel.
  • a second alternative embodiment consists in that the vessel console consists of a single, correspondingly thick console plate.
  • the support ring console consists of a single, appropriately dimensioned console plate.
  • clamping bracket consists of two spaced, parallel clamping tabs, which are connected at their ends by means of a transverse spacer element, or are rotatably connected to spaced support ring bracket plates, one in the middle , thick support ring bracket receives the spacer lever tabs for the operating lever and forms its pivot bearing.
  • the actuating lever consists of two spaced, parallel lever brackets, which, forming the pivot bearing, are connected by means of transverse spacer elements.
  • a tensioning element is formed from a tensioning lever rod running between the spaced-apart, parallel vessel brackets or between spaced-apart support ring bracket plates, with a hammer head resting thereon, which is connected to the rotary bearing connecting the two lever brackets and between two support ring console plates.
  • the tensioning lever rod running between two support ring bracket plates, forms an oval, closed tensioning bracket encompassing the vessel bracket.
  • FIG. 1 shows a detail of a vessel with a vessel console and support ring console and flip-top closure in a side view
  • FIG. 2 shows a partial plan view of the guide walls arranged on both sides to form a claw
  • FIG. 3 shows the side view like FIG. 1 with the folding lock in the open position
  • FIG. 4 shows the side view as in FIG. 1 with the folding lock in a secured open position
  • 5 shows a front view of the vessel and support ring in sections, with paired vessel console plates and a single support ring console plate
  • FIG. 6 shows the same front view of the vessel and support ring in sections on paired vessel console plates and support ring console plates
  • FIG. 7 shows the same front view with one single vessel console plate and a single support ring console plate
  • Fig. 8 is a front view with a single vessel console plate and paired support ring console plates.
  • a vessel 1 which consists, for example, 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, specifically by means of claws 6 distributed over the circumference on the vessel wall 1b and supports 4 assigned between them or these supports 4.
  • These supports 4 consist of additional fastening elements.
  • the additional fastening elements are provided between two adjacent claws 6.
  • Analog supporting ring consoles 8 are fastened to an upper flange 3a of the supporting ring 3.
  • Each support 4 consists (FIG. 1) on the upper flange 3a of the support ring 3, each of which has an opposing vessel console 7 and a support ring console 8, which by means of a hinged closure 9 to be described in more detail in a closing direction 10 into a secured closed position 11 can be clamped together and are easily detachable in an opposite actuation direction 12.
  • the flip-top closure 9 (FIG. 3, which shows the opening approximately halfway) consists of a tensioning bracket 13 encompassing the vessel console 7, which is pivotally mounted on an actuating lever 14, the actuating lever 14 being pivotable on with its upper end 14a the support ring bracket 8 is pivoted.
  • the clamping bracket 13 engages around the vessel console 7 and lies (FIG. 1) on the outer peripheral surface 3c of the support ring 3 and is locked by means of locking bolts 15 which are installed on both sides of the clamping bracket 13 in clamping brackets 13a, 13a.
  • the clamping bracket 13 moves during the opening movement in the opposite actuation direction 12 and back into the closed position 11 over the vessel console 7, the actuation lever 14 only moving away from the outer peripheral surface 3c of the support ring 3 removed (Fig. 3) and then approaches it again (Fig. 4). As a result, the open position 16 is reached.
  • the vessel bracket 7 forms a lower recess 7b in the side profile 7a, in which the support ring bracket 8 is accommodated with a clear distance. 5 to 8 different alternatives for the vessel console 7, the support ring bracket 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 thick console plate 18.
  • the support ring bracket 8 is made analogously to this from a single, correspondingly thick console plate 19.
  • the tensioning bracket 13 (FIGS. 5 and 7) is formed from two spaced, parallel tensioning brackets 13a and 13, which are connected at their ends 13b by means of a transverse spacing element 20.
  • spaced support ring bracket plates 8a are provided.
  • a rotary bearing 22 for rotating the tensioning bracket 13 with respect to the actuating lever 14 can also be provided in the support ring console plates 8a.
  • the spacer 20, which receives lever tabs 21 for the actuating lever 14, is provided for a rotary bearing 22.
  • the actuating lever 14 is formed in each case from two spaced, parallel lever brackets 21 which accommodate the rotary bearing 22 and the lever brackets 21 are connected by means of the transverse spacer elements 20.
  • a tensioning bracket 13 is in the form of a
  • clamping element 23 from a between the spaced, parallel vessel Brackets 7 or between the spaced support ring bracket plates 8a extending clamping lever rod 24 are formed with a hammer head 25 resting thereon.
  • the tensioning lever rod 24 itself is connected to the rotary bearing 22 connecting the two lever plates 21 and runs between two supporting ring bracket plates 8a.
  • the tensioning lever rod 24 runs between two support ring bracket plates 8a and forms an oval-shaped, closed tension bracket 26 encompassing the vessel bracket 7.
