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.
