Abstract

A vessel for metallurgical purposes and in particular a vessel for transporting molten metals, having a metal casing formed of individual tubular shells with a heat-resisting lining affixed thereto. Two stiffening rings extend circumferentially around the casing. Two vessel carrying trunnions are arranged opposite one another at the outer side of the metal casing and are supported by a plate connected to each stiffening ring. The stiffening rings are provided as an integrated component part of the metal casing. The middle area of the plate is positioned a distance from the metal casing. Upper and lower rim-line edge areas of the plate are connected, preferably welded, to the stiffening rings located adjacent thereto. The vessel carrying trunnions extend only outwardly from the plate. Depending upon the axial dimensioning of the vessel, more than two stiffening rings may be provided. The vessel of the present invention is uniformly stressed when subjected to combined load and heat and can withstand a characteristic temperature of up to 400.degree. C.
