Definitions

  • the invention relates to the storage and fastening of a tiltable vessel or converter on an open to one side, approximately horseshoe-shaped, surrounding the converter jacket at a distance from the support ring at three points by means of detachable support and connecting elements arranged at a distance of about 120 ° and attached to the circumference of the converter jacket Consoles, one of which lies in the tilting plane of the converter.
  • a releasable mounting for crucibles or converters is known, in which the crucible is supported on the supporting body surrounding it by means of upper and lower support devices.
  • the upper support devices consist of support bodies pivotably mounted on the ring-shaped support body and stop rigidly attached to the jacket of the crucible. bodies with counter support surfaces.
  • the lower support devices are rigidly attached to the crucible wall and can be adjusted to the underside of the supporting body by means of detachable wedge pairs.
  • the distance between the upper and lower supports is large.
  • the vessel becomes warmer than the supporting body and, due to the greater thermal expansion, an air gap is formed between the contact surfaces. Since the lining is thinner with each batch and the vessel wall becomes hotter, the expansion increases in the axial direction of the vessel.
  • the crucible or converter falls from the supports on the support bodies onto the wedge pairs after overcoming the friction in accordance with the air gap.
  • the stop bodies are acted upon when the column is erected.
  • the changing impact loads of the support devices mean a major disadvantage of the known storage.
  • the invention has set itself the task of avoiding this disadvantage, reducing the dimensions of the storage and designing such that the individual bearing elements do not have to be dismantled when removing the converter, while at the same time the connections between the support ring and the converter vessel are easily detachable and after exchange is easily connectable again.
  • the solution to the problem is to design the storage and attachment of a tiltable vessel or converter of the type mentioned above in such a way that the support ring has box walls which lead upwards or downwards, in each of which a support axis is parallel to the one at a distance vertically below or above the Converter jacket attached console is arranged, and the bearing housing of the pivot bearing associated with the support axles abut the top or bottom of the brackets, and that hinged screws are articulated to the bearing housings and are guided in slots through the brackets.
  • the converter vessel When carrying out the storage, the converter vessel can be fixed upright on the support ring.
  • the brackets are arranged on the converter jacket above the support ring and the box walls leading upwards accommodate the support axles with bearings, the bearing housings abutting the underside of the brackets.
  • the converter vessel can be attached to the support ring in a hanging manner.
  • the brackets are arranged on the converter jacket below the support ring.
  • the box walls of the support ring are led out downwards.
  • the support axles are located above the brackets and the bearing housings are on the top of the brackets.
  • the vessel is generally removed after the connecting elements have been loosened and the vessel has to be lifted slightly in a standing version or the vessel has been lowered slightly in a hanging version towards the open side of the support ring in the horizontal direction.
  • the converter is provided with a side spout, and there is no bearing on the support ring on the spout side in order to keep the heat of the liquid vessel contents away from the storage and to avoid damage from splashes of the liquid metal, and the vessel is replaced for space reasons in the direction opposite the spout, is pivoted upwards in a hanging arrangement after loosening the connecting elements and slightly lowering the support ring around the converter pivot pin and the vessel is moved to a repair stand with a converter change carriage.
  • a replacement of the converter vessel in the spout opposite direction is thus easily possible with the support ring open on this side.
  • the console lying on the spout side and the associated storage are not endangered due to the greater distance from the spout opening.
  • the folding screws in the blowing position of the converter are not additionally loaded by the weight of the container.
  • the converter 1 shown in FIG. 1 is suspended from a horseshoe-shaped support ring 3a.
  • the folding screws 8 establish the non-positive connection between the bearing housings 5 and the brackets 2 arranged below on the converter casing 1a with a preload corresponding to the converter counterweight.
  • the converter 1 is supported with its brackets 2 on a horseshoe-shaped, angled support ring 3b.
  • the console 2 lying in the tilting plane is arranged on the spout side between the spout opening and the angled support ring 3b.
  • the support axles 7 and the bearings 5, 6 are located in box walls 9 of the support ring 3b which are led out upwards and below the brackets.
  • the non-positive connection between converter 1 and support ring 3b is made by means of folding screws 8.
  • 1a denotes the converter jacket to which the brackets 2 are attached.
  • the 'support shafts 7 are fixedly supported by means of axle holders.
  • the support axles 7 supported at both ends have smaller dimensions than the known support pins arranged on the converter jacket and are largely unaffected by the heating of the converter jacket.
  • the support axles 7 take up conventional spherical bearings 6 enclosed in housings 5. The distance between the housing 5 and the box walls 9 as well as the oscillating mounting ensure a forced movement in all directions with thermal expansion of the converter.
  • the use of commercially available spherical bearings means an inexpensive solution.
  • Fig. 4 shows a section through the storage in the section plane IV-IV of Fig. 3.
  • hinged bolts 8 are pivotally connected in pockets, which engage in slots of the brackets 2.
  • the folding screws 8 are designed so that they can absorb the entire weight of the converter and ensure a secure connection between the bearing housing 5 and the brackets 2.
  • the number of folding screws 8 per bearing depends on the size and weight of the converter.
