Definitions

  • the invention relates to a metallurgical vessel for the transport of molten Metals according to the preamble of claim 1, and a method its manufacture according to the preamble of claim 7.
  • a vessel for metallurgical purposes is known from DE 195 38 530 C1. It points a heat-resistant liner, made of individual tubular Shots composite metal jacket, the circumferential with Stiffening rings is provided and on the two vessel support pins on the outside arranged opposite each other and by means of one each connected to the stiffening ring Plate are supported. Depending on the size of the axial extent of the vessel, there are more ais two stiffening rings provided as an integral part of the metal shell and the The central area of the plate is at a short distance from the metal jacket and the upper one and the lower brim-like edge region of the plate is adjacent to it horizontal stiffening ring connected.
  • the vessel support pin extends from the plate only to the outside.
  • a disadvantage of both constructions is that the plate segment is attached to the A long connecting seam is required and the shield segment to the metal jacket Stiffening rings must be aligned in a complex manner.
  • the object of the invention is to provide a metallurgical vessel for the transport of molten Specify metals, which has a simple construction, so that Manufacturing costs are lower compared to the known designs.
  • the shield segment is formed in one piece and at least the upper region has arms extending in both circumferential directions, which in the End area in cross section adapted to the respective subsequent stiffening ring and are provided with a welding edge.
  • the upper and lower areas of the shield segment extending arms in both circumferential directions.
  • the manufacturing costs can be reduced even further if you manufacture the
  • the supporting structure proceeds as follows.
  • the usually forged 360 ° stiffening ring is divided into three segments each with 120 ° extension. From two 120 ° segments of at least the upper stiffening ring and two 60 ° extensions each having shield segments, the supporting structure is formed.
  • the third 120 ° segment the respective stiffening ring can be used for the next vessel so that when producing two vessels, a total of at least two 120 ° segments for a third container.
  • the one when disconnecting the 360 ° stiffening ring Any cutting loss that occurs must be taken into account for the two 60 ° shield segments become.
  • the straight extension must also be taken into account if an im Cross section of oval vessel to be produced.
  • the one-piece shield segment to manufacture a thick sheet.
  • a thick sheet is created rolled, which, after being cut to size, can be bent warm or cold using a press becomes.
  • the choice of hot or cold forming depends on the thickness of the sheet and the selected material.
  • the desired contour and the hole for the trunnion are burned out and finally the final one is made by mechanical processing Final contour made.
  • the degree of deformation from block casting to thick sheet is at least the degree of forging corresponds to a conventionally manufactured shield segment.
  • stiffening rings proposed a new method of the invention. Instead of the stiffening rings too Forging, you can roll them as straight profiles and after cutting into lengths bend them into a 120 ° segment. The end areas are in relation to the welding edges machined.
  • FIGS. 1-3 show an external view, a top view and a section of the invention formed metallurgical vessel, here in the form of a steel ladle 1, shown.
  • This consists of a pipe section 2-4, which is heat-resistant Lining receiving metal jacket and a bottom 5 and foot elements 6.
  • Two circumferential stiffening rings 7, 8 are integrated in the metal jacket and a shield segment 9, 9 'arranged between them.
  • a support pin 11, 11 ' is welded in each case.
  • a tilting linkage 12 is attached to the left-hand outside, around the steel ladle 1 to be able to tilt using a crane, not shown here.
  • this embodiment is the top edge of the vessel 13 with a lid attachment designed as a ring lid 14 connected.
  • This ring cover 14 preferably has a frustoconical shape Cross section on. As can be seen in Figure 2, this steel ladle shown here has 1 has an oval cross section.
  • FIG. 3 shows two different embodiments in a partial section and in a view of the shield segment 9 shown. In this illustration, they are in the trunnion 11, 11 'hook hook loops 15, 15' can be seen.
  • the one-piece shield segment 9.1 has a recess 16 on the inside. In terms of area, this is larger than the inner surface 17 of the trunnion 11. In the recess an insulating layer can be placed to control the temperature in the trunnion lower.
  • the shield segment 9.2 shown in the right view is against this continuously smooth on the inside.
  • the shield segment 9 designed according to the invention is shown as a detail in FIG. 4. It has an almost rectangular central part 18, with the bore 10 for receiving the respective Trunnion 11, 11 '. In the upper and lower area close to the middle part 18 to the right and left each an extending arm 19, 19 ', 20, 20'. In shape and In cross-section, the end regions of these arms correspond to the respective stiffening ring 7, 8. They are designed as welding edges to the respective shield segment 9, 9 'with the Stiffening rings 7, 8 to be able to connect cohesively.
  • the middle part 18 is straight ( Figure 5), the circumferential extent corresponding to the degree of ovality.
  • the adjoining areas are bent to ensure a clean connection to the To ensure metal jacket or stiffening rings 7, 8.
  • FIGS. 7-9 show the proposed manufacturing process in the form of principle drawings shown for the stiffening rings 7, 8.
  • the manufacturing method for the lower stiffening ring 7 schematically explained.
  • the forged 360 ° full ring is divided into three 120 ° segments I, II, III in a first step.
  • the third 120 ° segment III is shown in dashed lines to clarify that this segment for the first vessel is not needed.
  • Figure 8 now shows how from the two 120 ° segments I, II and two 60 ° shield segments 9, 9 'the supporting structure is formed, the upper Stiffening ring 8 would belong.
  • the top stiffening ring 8 would be manufactured and cut in the same way.
  • the intermediate parts are the 60 ° sign segments are Trunnions 11, 11 'have been drawn in. When dimensioning the extension of the 60 ° shield segments 9, 9 ', the loss of cut occurring during separation must be taken into account.
  • the variant is the production of a steel ladle 1 with an oval cross section shown. Comparable to FIG. 5, the middle part 18 is straight and the two adjacent sections bent to a 30 ° segment, so that in total one 60 ° segment results. The consideration of cutting losses also applies here.
