Definitions
- the invention relates to a metallurgical vessel for the transport of molten metals according to the preamble of claim 1.
- a vessel for metallurgical purposes is known from DE 195 38 530 C1. It has a heat-resistant liner, made of individual tubular
- Shots composite metal jacket which is provided with stiffening rings extending in the circumferential direction and on which two vessel support pins are arranged on the outside opposite each other and supported by means of a plate connected to the stiffening ring.
- stiffening rings extending in the circumferential direction and on which two vessel support pins are arranged on the outside opposite each other and supported by means of a plate connected to the stiffening ring.
- more than two stiffening rings are provided as an integral part of the metal shell and the central region of the plate is at a short distance from the metal shell and the upper and lower brim-like edge region of the plate is connected to the adjacent stiffening ring.
- the vessel support spigot only extends outwards from the plate.
- the first stiffening ring which is closer to the floor, has an upward, nose-like extension in the area of the plate designed as a shield segment
- the second stiffening ring which is further away from the floor, has a downward nose-shaped extension in the area of the shield segment.
- the shield segment is welded in between the continuations, the transition from the respective continuation to the respective stiffening ring being rounded off both in the longitudinal section and in the top view, and the last-mentioned roundings transition into corresponding roundings of the shield segment without kinks.
- a disadvantage of both constructions is that a long connecting seam is required for fastening the shield segment to the metal jacket and the shield segment has to be aligned in a complex manner with respect to the stiffening rings.
- the object of the invention is to provide a metallurgical vessel for the transport of molten metals, which has a simple construction, so that the manufacturing costs are lower compared to the known constructions.
- the shield segment is formed in one piece and at least the upper region has arms which extend in both circumferential directions and which are adapted in cross-section in the end region to the respective subsequent stiffening ring and are provided with a welding edge.
- the upper and lower regions of the shield segment preferably have arms extending in both circumferential directions.
- the manufacturing costs can be reduced even further if you proceed as follows in the manufacture of the supporting structure.
- the usually forged respective 360 ° stiffening ring is divided into three segments each with 120 ° extension.
- the supporting structure is formed from two 120 ° segments of at least the upper stiffening ring and two shield segments each with 60 ° extension.
- the third 120 ° segment of the respective stiffening ring can be used for the next vessel, so that when two vessels are manufactured, a total of at least two 120 ° segments remain for a third vessel.
- the cutting loss that occurs when the 360 ° stiffening ring is separated must be taken into account for the two 60 ° shield segments.
- the straight extension must also be taken into account if an im
- the shield segment As a forged part.
- a thick sheet is rolled which, after being cut to size, is hot or cold bent using a press.
- the choice of hot or cold forming depends on the thickness of the sheet and the material selected.
- the desired contour and the hole for the trunnion are burned out and finally the final contour is created by mechanical processing.
- the degree of deformation from block casting to thick sheet corresponds at least to the degree of forging of a conventionally manufactured shield segment.
- a new method is also proposed with regard to the production of the stiffening rings. Instead of forging the stiffening rings, you can roll them as straight profiles and, after dividing them into lengths, bend them into a 120 ° segment. The end areas are machined with respect to the welding edges.
- FIG. 1 shows an external view of a steel ladle produced according to the invention
- Figure 2 is a plan view of Figure 1, Figure 3 left half, a section in the direction A-A in Figure 1; right half, the corresponding view,
- FIG. 4 shows the shield segment designed according to the invention in a view
- FIG. 5 shows a section in the direction B-B in FIG. 4,
- Figure 6 shows a section in the direction C-C in Figure 4
- FIGS. 1-3 An external view, a top view and a section of a metallurgical vessel designed according to the invention, here in the form of a steel ladle 1, is shown in FIGS. 1-3.
- This consists of a metal jacket formed from pipe sections 2-4, which receives the heat-resistant lining, and a base 5, as well as foot elements 6.
- Two circumferential stiffening rings 7, 8 and a shield segment 9, 9 'arranged between them are integrated into the metal jacket.
- a support pin 11, 11 ' is welded into a bore 10 (FIG. 4) of the shield segment 9.
- a tilting linkage 12 is attached to the outside on the left here in order to be able to tilt the steel ladle 1 by means of a crane, not shown here.
- the uppermost vessel edge 13 is provided with a lid designed as a ring lid 14. connected essay.
- This ring cover 14 preferably has a frustoconical cross section. As can be seen in FIG. 2, this steel ladle 1 shown here has an oval cross section.
- FIG. 3 two different types of shield segment 9 are shown in a partial section and in a view.
- the hook loops 15, 15 'suspended in the support pins 11, 11' 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 support pin 11.
- An insulating layer can be arranged in the recess in order to lower the temperature in the support pin.
- the shield segment 9.2 shown in the right view, however, is 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 middle part 18, with the bore 10 for receiving the respective trunnion 11, 11 '. In the upper and lower area, the central part 18 is adjoined to the right and left by an extending arm 19, 19 ', 20, 20'. In shape and cross section, the end regions of these arms correspond to the respective stiffening rings 7, 8. They are designed as welded edges in order to be able to connect the respective shield segment 9, 9 'to the stiffening rings 7, 8 in a materially integral manner.
- the middle part 18 is straight (FIG. 5), the circumferential extent corresponding to the degree of ovality.
- the adjoining areas are bent to ensure a clean connection to the metal jacket or stiffening rings 7, 8.
- FIGS. 7-9 show the proposed manufacturing method for the stiffening rings 7, 8 in the form of principle drawings.
- the manufacturing method for the lower stiffening ring 7 is explained schematically.
- 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 make it clear that this segment is not required for the first vessel.
- FIG. 8 now shows how the support structure is formed from the two 120 ° segments I, II and the two 60 ° shield segments 9, 9 ', the upper stiffening ring 8 being one of them. It goes without saying that the upper stiffening ring 8 would be manufactured and cut in the same way.
- FIG. 9 shows the variant in the production of a steel ladle 1 with an oval cross section. Comparable to FIG. 5, the middle part 18 is straight and the two adjacent sections are each bent into a 30 ° segment, so that a 60 ° segment results in total. The consideration of cutting losses also applies here.
