The invention relates to a vessel (1) for the metallurgical treatment of pig iron, steel melts and similar, in particular a converter vessel, mounted on a support ring (3), arranged at a separation by means of pivot pins, whereby the vessel (1) rests on the top flange (3a) of the support ring (3) by means of claws (6) on the vessel wall (1b) and a support (4) is detachably embodied with additional fixing elements on the top flange (3a) of the support ring (3). According to the invention, the disadvantage of having to work in hot, restricted regions which are difficult for the personnel to access can be avoided, whereby the support on the top flange (3a) of the support ring (3) comprises opposing vessel brackets (7) and support ring brackets (8) which can be tensioned together in a closing direction (10) by means of a hinged closure (9) until a secure closed position is achieved and which may be easily opened in the opposing operating direction (12).

Récipient (1) pour le traitement métallurgique de fonte brute, d'acier liquide et analogue, en particulier récipient de convertisseur, qui repose sur un anneau porteur (3) placé à une certaine distance (2) du récipient et pourvu de chevilles de basculement. Le récipient (1) repose sur la ceinture supérieure (3a) de l'anneau porteur (3) à l'aide de griffes (6) de la paroi (1 b) du récipient, l'appui (4) sur la ceinture supérieure (3a) de l'anneau porteur (3) étant formé démontable à l'aide d'éléments de fixation supplémentaires. Selon la présente invention, pour éliminer les inconvénients liés au travail du personnel dans une zone très chaude, exiguë et difficilement accessible, l'appui (4) sur la ceinture supérieure (3a) de l'anneau porteur (3) est constitué de consoles (7) de récipient et de consoles (8) d'anneau porteur opposées qui peuvent être contraintes les unes vers les autres dans une direction de fermeture (10) jusqu'à une position de fermeture sure, à l'aide d'une fermeture basculante (9), et qui sont facilement détachables dans une direction d'actionnement (12) opposée.
