Definitions
- the invention relates to a vessel for metallurgical purposes for the transport of molten metals.
- Such vessels not only serve to transport molten metals such as pig iron from the blast furnace to the pig iron mixer or from the pig iron mixer to the converter, but can also be a metallurgical treatment vessel.
- vacuum treatment has become increasingly important.
- the thermal load on the treatment vessel is particularly high, since the process involves operating at a high superheating temperature.
- this increased combined load of weight and heat can lead to undesired deformations, in particular if the vessel has an oval cross section.
- the distortions can be so severe that constrictions occur in the area of the stiffening rings.
- the trunnions can be crooked, so that difficulties arise when the crane hook is attached to the loops.
- DE 29 01 011 B1 discloses a trunnion or trunnion mounting for ladles, in which the trunnion projects with its foot in a cutout of the shell of the ladle and is welded to the edge of the cutout and attached to the side of the trunnion the plan has a rectangular fastening plate, which, lying between two stiffening rings attached to the jacket of the ladle, is welded to the jacket and to these stiffening rings. It is provided that the mounting plate cast on the bearing journal in a known manner is provided at its lateral edges with a molded leg, which in each case lies approximately perpendicular to the mounting plate and extends between the stiffening rings on the casing and welded to it.
- the object of the invention is to develop a vessel for metallurgical purposes that is evenly stressed when combined with load and heat and can withstand an intrinsic temperature of up to 400 ° C.
- the loops for the crane hooks should remain vertical under all operating conditions.
- the stiffening rings are not welded onto the metal jacket, but rather are an integral part of the partial jacket itself.
- Another aspect of the invention is the design and arrangement of the plate for fastening the support pins. In the central area it is at a distance from the metal jacket and the upper and lower brim-like edge area is welded to the stiffening rings, the vessel support pin advantageously being connected only to the plate and having no direct contact with the partial jacket.
- the stiffening rings are designed differently depending on the location, the radial extension, i. H . the thickness of the stiffening ring is an essential factor.
- the plate is advantageously attached so that it is welded directly to the lower stiffening ring and on the underside of the upper
- Stiffening ring is welded so that the 'plate is flush with the outer surface of the stiffening ring.
- the advantage of the vessel according to the invention can be seen in the fact that on the one hand no inadmissible deformations occur even at high inherent temperatures and the stresses in the material of the vessel are evenly distributed.
- One consequence of this is that the geometry of the vessel does not change under high weight and temperature loads. This can be seen in particular from the fact that the trunnions remain horizontal.
- FIG. 1 shows a view with partial opening of a vessel according to the invention including the hooked-in crane loops
- FIG. 2 shows a view rotated by 90 °.
- FIG. 1 shows a view with partial opening of a vessel according to the invention, which is designed here, for example, as a steel ladle 1.
- the pan 1 consists of a metal jacket and a pan base 2.
- the metal jacket is divided into three pipe sections 3 to 5 of different widths. Depending on the pan height and design, the number of pipe sections can be smaller or larger.
- the stiffening rings 6, 7, which are known per se are not placed on the socket jacket as is customary, but are integrated between two pipe sections 3, 4 and 4, 5, respectively.
- a further stiffening ring 8 is arranged as the top end, so that this stiffening ring 8 forms the pan edge.
- the individual stiffening rings 6 to 8 have a different axial and radial extension.
- Another aspect of the invention is that the plate 10, 10 'holding the support pin 9, 9' is at a distance from the metal jacket in the central region and the upper and lower rim-like edge regions 11, 12 with the adjacent stiffening ring 6, 7 is welded.
- the support pin 9, 9 ' extends from the plate 10, 10' only to the outside, so that there is immediately no thermal bridge between the support pin 9, 9 'and the metal jacket.
- Relief recesses 13-13 '" are arranged symmetrically around the pin area in the plate 10, 10'.
- the refractory lining 14 which consists of several layers, is arranged on the inside of the metal jacket. So that the pan 1 can be placed without problems , feet 15, 15 'are provided on the underside.
- the loops 16, 16' are shown, which are suspended in the respective trunnion 9, 9.
- a cover attachment is fastened to the upper stiffening ring 8, which here as Ring cover 17.
- the ring cover 17 preferably has a frustoconical cross section.
- FIG. 2 shows a view rotated by 90 ° of the same pan 1 according to the invention as in FIG. 1.
- the relief recesses 13-13 '"made in the respective plate 10, 10' are clearly visible. They are symmetrical about the support pin 9,
- a tilting linkage 18 is attached to the outside on the right here in order to be able to tilt the pan 1 by means of a crane.
- the different axial and radial extension of the respective reinforcing rings 6-8 can also be clearly seen in this illustration, wherein the stipulations for this depend essentially on the height and the circumference of the pan 1.
