ABSTRACT:
A metallurgical vessel for transporting molten metals with a metal jacket with a heat-resistant lining is disclosed. The jacket has two reinforcing rings extending in the peripheral direction and being secured to and integrated in the jacket. The vessel also has two one-part shield segments, each affixed to at least to one of two stiffening rings. The shield segments include arms that extend in both peripheral directions and are provided with a welding edge for welding to the stiffening rings. Two lifting lugs are disposed on the exterior of the vessel on opposing sides thereof and supported by the stiffening rings. A stiffening ring can be implemented as two 120° segments connected at their ends to the two shield segments which each extend over 60° along the periphery.
