Metallurgical vessel and method for producing the same

A metallurgical vessel for transporting molten metals implemented as a welded construction, comprising

• a metal jacket being made of individual lengths of tube and having a heat resistant lining and two axially spaced sections of stiffening rings which each extend about 120° along the periphery of the metal jacket and are secured to an outside surface of the metal jacket;
• two shield segments connected with the sections of the stiffening rings and forming a support structure, each shield segment has a rounded transition from the sections of the stiffening rings to the shield segment;
• and
• two lifting lugs arranged in opposing disposition on the outside surface of the metal jacket and being welded into an opening of the shield segment,
• wherein each shield segment extends over 60° along the periphery of the metal jacket and is formed as a single piece, with at least an upper region of the shield segment comprising arms extending in both circumferential directions of the metal jacket, and
• wherein end regions of the arms have a weld edge and a cross-section that is matched to a cross-section of the section of the stiffening ring proximate to the arms.

A method for producing a metallurgical vessel for transporting molten metals implemented as a welded construction, comprising the steps of:

• fabricating a metal jacket of individual lengths of tube;
• connecting to the metal jacket a support structure formed of stiffening rings and shield segments;
• and
• welding in each of the shield segments a corresponding lifting lug,
• wherein a 360° stiffening ring is separated into three segments, with each of the segments having a peripheral extent of 120°, and
• wherein the support structure is formed of two 120° segments and two shield segments having each a peripheral extent of 60°.
