Definitions

  • the invention relates to a tiltable metallurgical vessel with a metallurgical vessel at a distance at least partially surrounding the support ring, wherein the metallurgical vessel mounted support bracket rest on the support ring and the metallurgical vessel is releasably fixed to the support ring with a plurality of actuatable pressure medium cylinder clamping devices, each clamping device with an am metallurgical vessel fastened locking console cooperates and the tensioning device is designed to be movable from a release position releasing the locking console into a clamping position spanning the locking console and with the support ring and vice versa.
  • the invention relates to a tensioning device for supporting and securing a tiltable converter on a support ring at least partially surrounding it at a distance.
  • Metallurgical vessels of this type as they are used primarily in steel mills for the production and processing of molten steel, are exchangeable vessels that need to be replaced at intervals to renew their refractory lining or make any other repairs to them.
  • Tiltable metallurgical vessels such as converters
  • this vessel is therefore usually arranged in a support ring which is designed either as a closed annular or open horseshoe-shaped welded construction.
  • the support ring is pivotable about a horizontal axis and has trunnions which are mounted in a support frame.
  • the metallurgical vessel can be arranged in this support ring either hanging or resting on it or supported on it.
  • the present invention aims at avoiding these disadvantages and difficulties and has as its object to propose a tiltable metallurgical vessel in a further embodiment, in which the production of a secure connection and the opening of this secure connection between a metallurgical vessel and a support ring with a minimum number of components in a largely protected from heat and slag ejection environment can be performed.
  • the clamping device comprises at least one housing, a clamping armature, a pivot lever and an acting on the pivot lever pressure cylinder, that the clamping armature is pivotally guided in a slotted guide in the housing and hinged pivotably on the pivot lever and that the pivot lever in the housing pivot is supported.
  • the clamping anchor has a clamping anchor shaft and a clamping head with a support surface
  • the locking console has an insertion slot for receiving the clamping anchor shaft and a mating support surface for supporting the clamping head, that in the clamping position, the support surface of the clamping head is pressed against the mating support surface of the locking console and in the release position, the clamping head is positioned outside of the insertion slot and allows a lift-off movement of the metallurgical vessel from the support ring.
  • the clamping device forms or includes a toggle mechanism, which triggers a self-locking in the clamping position in a breakdown point and its Displacement is limited by a stop, which is preferably formed by the groove end of the slotted guide, the advantage achieved in itself already known clamping devices is realized equally in the simple design according to the invention in the same way. However, it is also possible to provide a stop limiting the displacement at a different location in the housing of the clamping device or in another way to achieve the same effect.
  • the tensioning device is designed for a high clamping force ensuring the secure maintenance of the tension, taking into account forces and moments which occur in particular during tilting of the metallurgical vessel during charging and discharging.
  • the breakdown point of the toggle mechanism can be traversed, it is necessary that the tensioning device is associated with an expansion element, with the otherwise occurring during the passage of the breakdown point tensile stresses are limited in height.
  • the expansion element is integrated in the clamping anchor.
  • the expansion element comprises a spring assembly formed by a plurality of disc springs.
  • the tensioning device is based on a special kinematics. This is determined by arranging a special slotted guide in the housing of the clamping device so that the clamping head of the clamping armature during the transition from the clamping position to the release position in a first phase of movement of the mating support surface on the locking console contrasting, thus predominantly in a direction normal to the counter support surface on the Locking console is moved and that the clamping head of the clamping armature is moved in a further movement phase with a predominantly pivotal movement of the region of the insertion slot of the locking console. Due to the special first movement phase, which includes the lifting of the clamping head of the counter-support surface on the locking console, an action of horizontal forces on the clamping device due to a frictional horizontal movement of the clamping head is avoided.
  • the slide guide in the housing of the clamping device is formed by an arcuate in its longitudinal extension groove into which a guide pin of the clamping armature engages and is guided in its sliding.
  • the clamping device Due to the arrangement of all components of the clamping device in a common housing, which is not an integrated part of the support ring, the clamping device forms a preassembled module that can be easily mounted on corresponding wall elements of the support ring. This in turn results in advantages for the maintenance personnel and the plant availability, since each clamping device can be replaced in case of necessary maintenance work within a very short time.
  • pneumatic cylinders are used to actuate the tensioning device.
  • Damage to the clamping device and in particular of the pressure cylinder by slag and Stahlausgianfe, especially during the Blasphase in a steel-producing converter, or by Wandlerermund crashing slag and Metallbrate can be avoided by the locking console is surrounded by an open toward the support ring housing and this enclosure is attached to the metallurgical vessel.
  • the pressure cylinder and the moving parts of the clamping device are housed protected in the housing of the clamping device and optionally shielded by components of the support ring.

  • the converter 1 consisting of a steel casing and an inner, not shown refractory lining, is supported in a support ring 2 with a short distance to the converter.
  • the support ring 2 which is usually designed as a horseshoe-shaped frame construction, is rotatably supported by two support pins 3a, 3b in a support frame 4 and equipped with a tilt drive, not shown here, whereby the adjustment of a vertical or an inclined operating position of the converter for charging feedstocks, blasting of the crude steel or parting of the liquid steel is made possible.
  • brackets 5a, 5b are welded, with which the converter rests on the support ring 2 in not shown pads.
  • tensioning devices 6a, 6b which are formed in the prior art of screw or a fluid-actuated linkage, the brackets 5a, 5b and thus the converter 1 are fixed in its predetermined position to the support ring 2 and this position even in the tilted operating position held by the converter.
  • the tensioning device 6 is in FIG. 2 represented in a possible embodiment as a preassembled module in the installed position to a welded to the converter, not shown locking console 7.
  • the clamping device 6 comprises a housing 8, which consists of several steel plates and which forms a frame for receiving the individual components of the clamping device 6 as a welded construction.
  • One or more support plates 8a, 8b of the housing with a machined mounting surface allow rapid assembly of the entire clamping device at the designated positions of the support ring 2 (FIG. Fig. 3a, 3b ).
  • support plates 8c At two of the support plate 8a normally towering and parallel to each other positioned support plates 8c slide guides 10 are provided which are opposite to each other and in which a clamping anchor 9 is slidably guided.
  • Pivot levers 12 are pivotally mounted at one end in a support bearing 13 in the support plates 8c.
  • a trained as a pneumatic cylinder pressure cylinder 14 is tiltably supported in bearing housings 15, which are also attached to the support plates 8c.
