Abstract:
A vessel for metallurgical purposes, for transporting molten metals, comprising:a metal casing composed of individual tubular lengths and having a base and an upper edge;two reinforcement rings which run in a circumferential direction and are integrated in the metal casing at an axial distance from one another, a first one of the rings being closer to the base of the casing and a second one of the rings being further away from the base;two shield segments externally arranged on the reinforcement rings on opposite sides of the casing, each shield segment being at a short distance from the metal casing, the first reinforcement ring which lies closer to the base having a thickness greater by up to a factor of 4, and the second reinforcement ring which lies further away from the base having a thickness greater by a factor of 6 than a thickness of the metal casing, the first reinforcement ring having an axial extent at least equal to an axial extent of the second reinforcement ring;two bearing lugs, a respective lug being mounted to each of the shield segments; anda lid attachment fastened to the upper edge of the casing, the lid attachment having a frustoconical cross section, the first reinforcement ring which lies closer to the base having an upward directed extension formed as a projection in a region of the shield segment, and the second reinforcement ring, which lies further away from the base, having a downwardly directed extension formed as a projection in the region of the shield segment, the shield segment being welded in between the extensions, a transition from a respective one of the extensions into a respective one of the reinforcement rings being rounded both in longitudinal section and in plan view, the rounded transition merging smoothly into corresponding rounded sections of the shield segment.
