Definitions

  • the present invention relates to the field of metallurgical plants, specifically a metallurgical vessel for liquid metals.
  • the invention relates to a tiltable metallurgical vessel with a round cross section, the metallurgical vessel being - at least partially - surrounded by a support ring and the support ring being at a distance from the metallurgical vessel in the radial direction.
  • the invention relates to a method for fixing a tiltable metallurgical vessel on a support ring, as well as a method for detaching a tiltable metallurgical vessel from the support ring.
  • Tiltable metallurgical vessels are used for the production of metals - especially in steel production. These metallurgical vessels are held by a support ring that surrounds these vessels. The support ring is at a distance from the vessel because - due to the high operating temperatures of the liquid metal - the metallurgical vessel expands.
  • the metallurgical vessel is provided with a lining to hold liquid steel. This brick lining must be renewed at certain intervals. In particular with metallurgical vessels for the AOD (Argon Oxygen Decarburication) process, for the production of stainless steels, a frequent change of the brick lining is necessary. In order not to lose too much production time, the metallurgical vessel is used separated from the support ring and a new vessel with renewed brick lining installed.
  • the stud bolt has a wedge-shaped passage opening in the horizontal direction, and the locking bracket likewise has an opening.
  • a wedge is inserted through the locking bracket and the stud bolt through this passage opening.
  • the wedge is moved by a hydraulic cylinder - which is fixedly attached to the support ring.
  • the DE 102013224072A1 shows a fastening system for tiltable metallurgical treatment vessels, in particular converters.
  • the DE 2457606A1 discloses a floating bearing for a trunnion of a converter.
  • the object of this invention is to provide a tiltable, exchangeable metallurgical vessel which is fixed to a support ring, so that, in spite of large temperature differences, reliable fixing of the metallurgical container with the support ring and also a reliable release is made possible.
  • the object is achieved in that the metallurgical vessel has at least three consoles with at least one pin.
  • the support ring also has at least three receiving openings. The pins can penetrate into these receiving openings, the receiving openings allowing the pin to be displaced in the radial direction.
  • the metallurgical vessel has a circular cross section and the support ring has - at least partially - a circular design.
  • the support ring can be circular or open on one side and be of a U-shaped or horseshoe-like design. When heated, the metallurgical vessel expands in its diameter, which mainly leads to a radial displacement of the consoles and thus the pins.
  • a floating locking device arranged inside the support ring ensures that the pin is secured against falling out of the receiving opening and the console.
  • the floating locking device can brace the pin in such a way that the bracket is pressed onto the support ring via the pin.
  • the receiving openings should be designed so that they are larger than the dimensions of the pin.
  • the receiving opening is made significantly larger than the dimensions of the pin in this direction.
  • the radial direction is understood to mean the direction from the inner radius of the support ring in the direction of the outer radius of the support ring. This configuration is intended to enable relative movements between the support ring and the metallurgical vessel, which are caused by deformation or thermal expansion.
  • the temperature range on the outer surface is at room temperature and in operation, if there is liquid metal in the metallurgical vessel, at temperatures of up to 400 ° C.
  • the support ring in particular heats up on the side facing the metallurgical vessel. This also leads to expansion of the support ring.
  • the relative movements are thus triggered both by movements of the metallurgical vessel and by the support ring.
  • the floating locking device inside the support ring is used to ensure that the relative movements are followed during operation. In this context, everything is understood to be mounted in a floating manner, which is suitable to allow relative movements.
  • Floating is understood to mean that the locking device is held in a floating position in the support ring, which secures the pin against falling out of the receiving opening and follows relative movements - of the pin with respect to the support ring - in at least the radial direction of the support ring.
  • Floating is understood in connection with the invention that the locking device is not fixed in place on the support ring, but can move at least in the radial direction of the support ring.
  • This floating locking device is temporarily held by holding devices when the metallurgical vessel is detached from the support ring.
  • Such temporary holding devices can, for example, be encompassing guides which do not hinder the compensation of the relative movements - preferably in the radial direction - during operation.
  • This locking device would be mounted stationary - as in the EP 1533389 A1 - this can lead to problems. Relative movements between the support ring and the metallurgical vessel can lead to deformations on a component and thus the release of the locking device would no longer be possible, or other components could be damaged.
  • a pin, wedge or the like can be provided as a securing element. The pin must be designed accordingly so that the connection of the securing element with the pin is possible.
  • the pin should have a wedge pressing surface and the floating locking device should have a wedge.
  • the wedge is brought into connection with the wedge pressing surface to secure the pin against falling out of the receiving opening and the console.
  • Possible designs of the wedge pressing surface are a lateral passage opening or at least a lateral groove.
  • the lateral passage opening or the lateral groove are preferably designed to be wedge-shaped.
  • the floating mounting of the locking device enables compensation so that the wedge can align itself with the wedge pressing surface during the connection. This has the advantage that no constraining forces have to be exerted if the alignment of the wedge and the wedge pressing surface do not exactly match.
  • the floating locking bracket aligns itself automatically.
  • the locking device is against a End position limitation pressed. This limit position makes it possible to exert a corresponding force so that the wedge can be pressed onto the wedge pressing surface of the pin. While the wedge and the wedge pressing surface are being brought into connection, the floating locking device can also be in contact with the end position limit.
  • Bringing in connection is understood - for example in the case of a lateral passage opening - to mean that the wedge is pressed into the lateral passage opening.
  • the wedge and the wedge pressing surface are designed in such a way that prestressing can be achieved in the longitudinal direction of the pin, that is to say the console is pressed onto the support ring.
  • a lateral passage opening is understood to mean anything that is suitable for a wedge to penetrate.
  • the lateral passage opening should extend over the entire cross section so that at least part of the wedge can penetrate the pin.
  • An end position limiter is also required to loosen the pin-wedge connection.
  • the end position limitation for releasing is advantageously opposite the end position limitation for fixing.
  • the locking device consists of a base body with a base body opening through which the pin can penetrate.
  • a cylinder is mounted on the body and the cylinder is directly connected to the wedge.
  • This embodiment has the advantage that the pin penetrates the base body opening and the wedge is pressed onto the wedge pressing surface when the cylinder is actuated.
  • the base body opening serves as an end position limit, which serves to press the wedge - through the cylinder - accordingly onto the wedge pressing surface.
  • An edge or an edge surface of the base body opening - that which lies opposite a fastening of the cylinder - is pressed against the pin when it is pressed in. This ensures that the cylinder has the appropriate force can apply to press in the wedge.
  • This embodiment is a very simple and space-saving embodiment. This embodiment is particularly suitable for small metallurgical vessels with a correspondingly small support ring.
  • the receiving openings of the support ring are elongated holes. These elongated holes extend in the radial direction. This is a particularly preferred embodiment to ensure the relative movement of the pin and the support ring and thus to avoid constraining forces.
  • the dimensions of the receiving opening in the radial direction are advantageously at least twice as large as the dimensions of the pin in the radial direction. It should at least be ensured that a relative movement of at least the dimension of the pin in the radial direction is possible in the radial direction.
  • a spacer sleeve through which the pin protrudes is used on the console.
  • the pin is supported on the spacer sleeve instead of on the console.
  • the spacer sleeve is designed so that the pin can protrude, but a head of the pin is supported on the sleeve. It is also conceivable that the spacer sleeve is located between the console and the support ring.
  • This embodiment has the particular advantage that in the event of unforeseen events - for example if the cylinder is defective - the pin above the support ring can be cut through in order to be able to lift off the metallurgical vessel.
  • the spacer sleeve should be at least 50mm high. Accessibility is easily possible through this spacer sleeve and the support ring and the rest of the metallurgical vessel are not damaged by the cutting through.
  • cutting through can be done with a flame cutter, for example.
  • the locking device has a position monitoring device. This position monitoring device always ensures that the pin is secured against falling out of the receiving opening and the console.
  • a special design provides that the metallurgical vessel has four consoles with pegs and the support ring has four receiving openings.
  • a fourth bracket with pegs is attached to ensure a secure connection between the support ring and the metallurgical vessel in the event of a peg failure.
  • the fourth pin has a redundant design and increases the security of the connection between the support ring and the metallurgical vessel, so that safe operation is still guaranteed in the event of a pin-wedge connection failure or cracks in a console.
  • the position monitoring device takes place by means of a pressure measuring device and a position monitoring device of the cylinder.
  • the pressure measuring device is used to ensure that a certain minimum pressure is applied to the cylinder during operation.
  • the pressure measuring device also monitors that a maximum pressure is not exceeded. If a specified maximum pressure is exceeded, this could lead to a problem when removing the wedge from the wedge pressing surface. If the wedge is pressed in too hard, the force may no longer be sufficient to pull the wedge out.
  • the position monitoring device can take place, for example, by directly measuring a position of a piston rod of the cylinder or by measuring the flow rate of the fluid with which the cylinder is acted upon. The position of the wedge can be determined by measuring the flow rate.
  • a particularly preferred embodiment for the metallurgical vessel is an argon oxygen converter, which has a capacity of up to 180 t.
  • AOD Argon Oxygen Converters
  • the metallurgical vessels are typically smaller than metallurgical vessels for other steelmaking processes.
  • the smaller metallurgical vessels for AOD converters therefore also have a smaller support ring. The space requirement within the support ring is less, which means that the floating locking device described is particularly well suited for AOD converters.
  • a metallurgical vessel which has at least three pegs, is connected to a support ring.
  • the support ring has receiving openings for pins.
  • the pegs penetrate the receiving openings when the vessel is placed.
  • each pin is secured against falling out of the console and the receiving opening by means of locking devices floating in the interior of the support ring, whereby the metallurgical vessel is fixed on the support ring.
  • Each pin should be secured in such a way that there is as little play as possible between the support ring and the console. This means that the securing takes place in such a way that the pin is pretensioned as much as possible.
  • An advantageous embodiment of the method provides that the floating locking device is constantly monitored by means of a position monitoring device. As a result, possible problems of securing the pin against falling out of the console and the receiving opening can be quickly identified during operation.
  • a particularly advantageous embodiment provides that the floating locking device has a wedge and the wedge is pressed in with a maximum of 75% of an available maximum force - to remove the wedge.
  • Limiting the force to a maximum of 75% of the maximum available force - for removing the wedge - ensures that there are still power reserves available for removing the wedge - from the lateral opening or a lateral groove in the pin.
  • the piston rod reduces the effective area of the piston.
  • the object according to the invention is achieved by the above-mentioned method for releasing a fixation of the metallurgical vessel from the support ring.
  • the fixation of pins by floating locking devices is released.
  • the wedges are removed from the wedge pressing surface of the tenons by the floating locking devices.
  • the metallurgical vessel is then dated
  • Fig. 1 shows a metallurgical vessel 1 and a support ring 2.
  • the metallurgical vessel 1 has three brackets 12 and is connected to the support ring 2, which has three receiving openings 14, by three pins 10.
  • the pins 10 are each secured with a floating locking device 20 against falling out of the console and the receiving opening 14 of the support ring.
  • the floating locking device 20 has a cylinder 22 and a wedge 21.
  • the pin 10 is fixed by the wedge 21.
  • FIG. 2 Another embodiment for the connection of a metallurgical vessel 1 with a support ring 2 is shown.
  • This embodiment differs in that the support ring 2 is closed.
  • a spacer sleeve 13 is attached between the pin 10 and bracket 12.
  • This spacer sleeve 13 is used so that in the event of failure of the floating locking device 20, the pin 10 and the spacer sleeve 13 can be severed, for example with a welding torch.
  • the receiving openings 14 - designed as elongated holes - extend in the radial direction in order to enable a relative movement of the bracket and the pin with respect to the support ring.
  • a position monitoring device 28 ensures that the wedge 21-pin 10 connection is always upright, so that the pin is prevented from falling out of the bracket 12 and the receiving opening 14. All other reference numbers have already been used in the description of Figure 1 explained.
  • Fig. 3 the connection of pin 10 and the floating locking device 20 is shown enlarged.
  • the cylinder 22 is mounted on a base body 23.
  • the cylinder 22 is directly connected to a wedge 21.
  • This base body 23 has a base body opening 24 which has an end position limitation 25, and an end position limitation for releasing 29 is also shown.
  • the pin has a wedge pressing surface 11 which is used for this purpose to press in the pin 10 - over the wedge 21 - and thereby fix the connection between the support ring 2 and the metallurgical vessel.
  • the pin 10 and the base body opening 24 each have insertion bevels. These insertion bevels 27, 15 serve to center the floating locking devices 20 when the pins 10 are inserted.
  • insertion bevels 27, 15 represent only one possibility; it is also conceivable that other insertion aids are used.
  • the holding device 26 - as shown - is an encompassing guide 26 and at the same time acts as a limit position when the base body 23 does not have a base body opening 24.
  • Fig. 4 is a plan view of the floating locking device 20.
  • the essential components such as cylinder 22, wedge 21, base body 23 with the base body opening 24 and end position limit 25 are shown.
  • the reference symbols in Fig. 4 were already in Fig. 3 explained.
  • FIGs 5a and 5b possible embodiments of the pin 10 and the wedge pressing surface 11 are shown.
  • the wedge pressing surfaces 11 are two lateral grooves 17. These are only intended to represent two examples of how these wedge pressing surfaces 11 are designed. It is also conceivable that the pin 10 has only one lateral groove 17.
  • the Figure 5c is a possible design for a wedge 21 - for the passage opening 16 of Figure 5a - shown.
  • Fig. 5d is a possible embodiment for a wedge 21 - for the two lateral grooves 17 from Figure 5b - shown.
  • Fig 6 an embodiment of a metallurgical vessel 1 with a support ring 2 and four brackets 12 is shown.
  • This embodiment variant has the advantage that if a bracket 12, a pin 10 or the floating locking device (not shown) fails, the metallurgical vessel 1 fixed on the support ring 2 is still safe to operate.
  • Fig. 7 and Fig. 8 the expansion of the metallurgical vessel 1 is shown schematically.
  • the warm metallurgical vessel 3 has a larger diameter - shown by the dash-dotted lines.

  • the change in the support ring is shown as a warm support ring 4.
  • the position of the pin 10 relative to the receiving opening 14 also changes Fig. 8 if this relative movement is shown enlarged, the movement of the floating locking device 20 is also shown - schematically in the lower area.
  • Fig. 8 it can also be seen that the relative movement of the pin 10 and the receiving opening 14 can be less in the area of the open side than, for example, in the lower area where the locking device 20 is shown.
  • the radial displacement of the pin 10 in the receiving opening 14 is shown. The movement of the floating locking device 20 to follow this radial displacement is shown in FIG Fig. 8 also evident.
