ABSTRACT A metallurgical vessel of this kind, more particularly an interchangeable steel plant converter, comprises a supporting ring with equiaxial trunnions secured thereto and mounted rotatably in tilt-bearings, the said bearings resting upon foundation columns; and also comprises tension elements hinged to the upper side of the supporting ring and displaceable in slots, the tension elements passing through the supporting ring and being connected detachable, in the vicinity of the underside of the supporting ring, by tensioning heads and tensioning nuts to lugs integral with the vessel, and with load-absorbing means, for the horizontal position of the vessel, projecting between the said supporting ring and lugs. In a vessel attachment of this kind, which provides a mounting as free as possible from thermal stress upon the supporting ring which surrounds it with an inter- vening gap, and which also has the advantage of providing a play free mounting between the vessel and the supporting ring, the vessel being connected to the supporting ring, in all positions of tilt, with prestressing of the tension elements, it is pro- posed, in order to make it possible to use the said attachment with prestressable tension elements and, at the same time, to provide only short-stroke lifting cylinders on the vessel-changing car, that the tension elements, after the tensioning nuts have been released, be disengageable from the lugs through recesses, open on one side, in the said lugs, at right angles to the longi- tudinal axes of the tension elements. Displacement of the said tension elements is effected, on the one hand, by tension elements adapted to pivot about the upper joint on the upper side of the supporting ring or, on the other hand, by tension elements divided into at least two longitudinal sections connected together by means of a universal joint which absorbs tension forces.
