A vessel for metallurgical purposes, for transporting molten metals, having a metal casing which accommodates a refractory lining, is composed of individual tubular lengths. Two reinforcement rings which run in the circumferential direction and are integrated in the metal casing at an axial distance from one another, and on which two bearing lugs are arranged opposite one another on the outside and are supported by in each case one plate which is connected to the reinforcement rings. If appropriate a lid attachment is fastened to the vessel edge, which lid attachment is frustoconical in cross section. The first reinforcement ring, which lies closer to the base, has an upwardly directed extension, which is designed in the form of a projection, in the area of the plate, which is designed as a shield segment. The second reinforcement ring, which lies further away from the base, has a downwardly directed extension, which is designed in the form of a projection, in the area of the shield segment. The shield segment is welded in between the extensions. The transition from the respective extension into the respective reinforcement ring is rounded both in longitudinal section and in plan view, and the latter rounded sections merging smoothly into corresponding rounded sections of the shield segment.
L'invention concerne une cuve destinée à la métallurgie, pour le transport de métaux en fusion, pourvue d'une enveloppe dans laquelle se loge une garniture résistant à la chaleur, cette enveloppe étant constituée de tronçons tubulaires individuels assemblés et comportant deux anneaux de rigidification intégrés dans ladite enveloppe, séparés axialement l'un de l'autre et s'étendant dans le sens circonférentiel. Sur le côté extérieur de ladite enveloppe, sont disposés deux tourillons de support opposés qui sont supportés chacun au moyen d'une plaque reliée aux anneaux de rigidification, une pièce rapportée de couverture étant éventuellement fixée au bord de la cuve et présentant une section du type cône. Le premier anneau de rigidification (6), qui est le plus proche du fond (2), présente, dans la zone de la plaque se présentant sous la forme d'un segment de blindage (16, 16'), un prolongement (17) dirigé vers le haut, en forme de tenon, et le second anneau de rigidification (7), qui est le plus éloigné du fond (2), présente, dans la zone du segment de blindage (16, 16'), un prolongement (18) dirigé vers le bas, en forme de tenon, le segment de blindage étant soudé entre les deux prolongements (17, 18). La zone de transition entre un prolongement (17, 18) et son anneau de rigidification (6, 7) est arrondie aussi bien vue en coupe longitudinale qu'en plan, et la transition entre les parties arrondies (23, 24) et les parties arrondies (25, 26) correspondantes du segment de blindage (16, 16') se fait sans coude.
