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, wherein the metallurgical vessel of a support ring - at least partially - is surrounded and the support ring in the radial direction has a distance from the metallurgical vessel.
- the invention relates to a method for fixing a tiltable metallurgical vessel to a support ring, and to a method for releasing a tiltable metallurgical vessel from the support ring.
- metallurgical vessels For the production of metals - especially in steelmaking - tiltable metallurgical vessels are used. These metallurgical vessels are held by a supporting ring surrounding these vessels. The support ring has a distance from the vessel, because - by high operating temperatures of the liquid metal - the metallurgical vessel expands.
- the metallurgical vessel is provided with a lining for receiving liquid steel. This lining must be renewed at certain intervals.
- AO argon oxygen decarburization
- locking brackets are welded to the metallurgical vessel, which is penetrated by a stud - which is attached to the support ring - interspersed.
- the stud has a wedge-shaped passage opening in the horizontal direction, as well as the locking console has an opening. Through this passage opening a wedge is inserted through the locking console and the stud. The wedge is moved by a hydraulic cylinder - which is fixed to the support ring - moves.
- the disadvantage of this device is that larger heat-induced deformations of the metallurgical vessel lead to deformation of the locking console and / or stud bolt and connecting and disconnecting the locking console and studs is only with difficulty, or until cooling must be awaited - until the metallurgical vessel again almost the original dimensions has taken.
- the object of this invention is to provide a tiltable exchangeable metallurgical vessel, which is fixed to a support ring, so that, despite large temperature differences, a reliable fixing of the metallurgical container with the support ring and also a reliable release is enabled.
- 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, wherein the receiving openings allow a displacement of the pin 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 may be circular or open on one side and be a U-shaped or horseshoe-like design. When heated, the metallurgical vessel expands in diameter, which leads mainly to a radial displacement of the brackets and thus the pin.
- a floating bearing arranged inside the support ring locking device ensures that the pin is secured against falling out of the receiving opening and the console. In addition, the floating bearing locking device can clamp the pin such that over the pin, the console is pressed onto the support ring.
- the receiving openings should be designed so that they are larger than the dimensions of the pin. In the radial direction of the support ring, the receiving opening is made significantly larger than the dimensions of the pin in this direction. Radial direction is understood in relation to this invention, the direction of the inner radius of the support ring in the direction of the outer radius of the support ring.
- the temperature range at the outer surface is at room temperature and in operation when liquid metal is in the metallurgical vessel at temperatures of up to 400 ° C.
- heat radiation of the metallurgical vessel especially the support ring heats up at the side facing the metallurgical vessel. This also leads to expansions of the support ring.
- the relative movements are thus triggered both by movements of the metallurgical vessel, as well as by the support ring.
- the floating inside the support ring mounted locking device is used to follow the relative movements during operation. In this context, floating is understood to mean everything that is suitable for permitting relative movements.
- This floating bearing locking device when the metallurgical vessel is detached from the support ring, temporarily held by holding devices.
- 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 mounted stationary - as in the EP 1533389 A1 - this can lead to problems. Due to relative movements between the support ring and the metallurgical vessel, it can lead to deformations of a component and thus the release of the locking device would no longer be possible, or it could lead to damage of other components.
- a more secure securing of the pin can be ensured by the floating-mounted locking device.
- a fuse element a pin, wedge or the like can be provided. The pin must be carried out accordingly, so that the connection of the fuse element is made possible with the pin.
- the pin should have a wedge pressing surface and the floating bearing locking device a wedge.
- the wedge is brought to secure the pin, against falling out of the receiving opening and the console, associated with the wedge pressing surface.
- Possible embodiments of the wedge pressing surface are a lateral passage opening or at least one lateral groove.
- the lateral passage opening or the lateral groove are preferably designed wedge-shaped.
- the floating bearing of the locking device allows compensation to allow the wedge to align while in contact with the wedge pressing surface. This has the advantage that no constraining forces must be exerted if the orientation of the wedge and the wedge pressing surface do not coincide exactly. During insertion of the wedge, the floating locking console automatically aligns itself.
- the locking device is pressed against an end position limit.
- This Endlagenbegrenzung makes it possible to exert a corresponding force, so that the wedge can be pressed onto the wedge pressing surface of the pin.
- the floating bearing locking device can also already abut against the end position limit.
- Under connecting is understood - for example, in a lateral passage opening - that the wedge is pressed into the lateral passage opening.
- the wedge and the wedge press surface become like that stated that a bias in the longitudinal direction of the pin is achieved, so the console is pressed onto the support ring.
- a side passage opening everything that is suitable for a wedge can 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 limitation is necessary for the release of the tenon - wedge connection.
- the end position limit for the release is advantageously opposite the end position limit for fixing.
- the locking device consists of a base body with a base 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 of the base body and, upon actuation of the cylinder, the wedge is pressed onto the wedge pressing surface.
- the base opening serves as an end position limit, which serves to press the wedge - through the cylinder - according to the wedge pressing surface.
- An edge or an edge surface of the main body opening - which is opposite to a mounting of the cylinder - is pressed against the pin during pressing. This ensures that the cylinder can apply the appropriate force to press the wedge.
- This embodiment is a very simple and space-saving design. 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 slots extend in the radial direction. This is a particularly preferred embodiment of the relative movement of pins and To ensure support ring and thus avoid forcing forces.
- the dimension of the receiving opening in the radial direction is at least twice as large as the dimension of the pin in the radial direction. It should at least be ensured that in the radial direction, a relative movement of at least the dimension of the pin in the radial direction, is possible.
- 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 between the console and the support ring is located.
- This embodiment has the particular advantage that in case of unforeseen events - for example in case of defect of the cylinder - the pin can be cut above the support ring in order to lift the metallurgical vessel can.
- the spacer sleeve should be at least 50mm high. Through this spacer, the accessibility is quite possible and the support ring and the remaining metallurgical vessel are not damaged by the cutting.
- the cutting can be done in this embodiment, for example, with a flame cutter.
- the locking device has a position monitoring device. By this position monitoring device is always ensured that the pin is secured against falling out of the receiving opening and the console.
- a special design provides that the metallurgical vessel four consoles with spigot and the support ring four Has receiving openings.
- a fourth bracket with spigot is attached to ensure the secure connection of support ring and metallurgical vessel in case of failure of a pin.
- the fourth pin is designed to be redundant and increases the security of the connection of the support ring and metallurgical vessel, thus a safe operation is still guaranteed in case of failure of a pin - wedge connection or cracks in a console.
- a further preferred embodiment provides that 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 serves 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. Exceeding a specified maximum pressure could result in a problem in removing the wedge from the wedge pressing surface. If the wedge is pressed in excessively, the force to pull out the wedge may not be sufficient.
- the position monitoring device can be made for example by direct measurement of 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. By measuring the flow rate, the position of the wedge can be determined.
- a particularly preferred embodiment for the metallurgical vessel is an argon-oxygen converter which has a capacity of up to 180 tons.
- Argon Oxygen Converters (AOD) require frequent replacement because the brick lining is subject to high wear.
- the metallurgical vessels are usually smaller than metallurgical vessels for other steelmaking processes.
- the smaller metallurgical vessels for AOD converter thus also have a smaller support ring. The space requirement within the support ring is lower, bringing the described floating bearing locking device is particularly well suited for AOD converter.
- a metallurgical vessel having at least three pins is connected to a support ring.
- the support ring has receiving openings for pins. The pins penetrate when placing the vessel in the receiving openings.
- the support ring and the metallurgical vessel are fixed together in this way.
- relative movements between the pin and the support ring are followed by the floating bearing locking device, so that by this relative displacement, the floating bearing locking device follows the relative movement of the pin, opposite the support ring.
- relative movements in the radial direction of the support ring, between bracket with pin and support ring are made possible, which arise for example by thermal expansion. Allowing these relative movements, serves to avoid unwanted deformations of components of the connection of metallurgical vessel and support ring.
- An advantageous embodiment of the method provides that the floating-mounted locking device by means of a position monitoring device constantly is monitored. As a result, possible problems of securing the pin against falling out of the console and the receiving opening, during operation can be detected quickly.
- a particularly advantageous embodiment provides that the floating-mounted locking device has a wedge and the wedge with a maximum of 75% of an available maximum force - is pressed - for removing the wedge.
- the force By limiting the force to a maximum of 75% of the maximum available force - to remove the wedge, it is ensured that for the removal of the wedge - from the lateral passage opening or a lateral groove of the pin - are still power reserves available.
- due to the piston rod due to the piston rod, only one reduced force is possible for one direction.
- the piston rod reduces the effective area of the piston.
- the object of the invention is achieved by the aforementioned method for releasing a fixation of the metallurgical vessel from the support ring.
- the fixation of pins by floating mounted locking devices is released.
- the wedges are removed from the wedge-pressing surface of the studs by the floating-type locking devices.
- the metallurgical vessel is lifted from the support ring. Due to the design with floating locking devices, the release is much easier, as permanent deformations are largely avoided by the floating locking devices.
- 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 floating-type locking device 20 has a cylinder 22 and a wedge 21. The pin 10 is fixed by the wedge 21.
- FIG. 2 a further 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 pin 10 and console 12, a spacer sleeve 13 is attached.
- This spacer sleeve 13 serves to ensure that in the event of failure of the floating locking device 20, the pin 10 and the spacer sleeve 13 can be cut, for example, with a welding torch.
- the receiving openings 14 - designed as elongated holes - extend in the radial direction to allow a relative movement of the bracket and pin relative to the support ring.
- a position monitoring device 28 ensures that the wedge 21 - pin 10 connection is always upright, so that falling out of the pin from the bracket 12 and the receiving opening 14 is prevented. All other reference numerals have already been in the description of FIG. 1 explained.

- the pin 10 and the base opening 24 each have insertion bevels. This insertion bevels 27, 15, serve to ensure that the floating bearing locking devices 20 are centered during insertion of the pins 10.
- chamfers 27, 15 represent only one possibility, it is also conceivable that other insertion aids are used. If the wedge 21 does not press on the wedge pressing surfaces 11, the floating-type locking device 20 is held in position by holding devices 26. It is also conceivable, for example, that the holding device 26 -as shown-is a encompassing guide 26 and at the same time acts as an end-position limit when the base body 23 has no base body opening 24.
- Fig. 4 is a plan view of the floating bearing locking device 20.
