Abstract
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).
