摘要： Disclosed is a metallurgical vessel, in particular a converter for treating liquid molten metals, in particular steel, formed of a refractory lining and a supporting metal shell that surrounds the refractory lining. The vessel is composed of welded together shell rings and dished parts of creep-resistant steel with plate thicknesses of up to 100 mm. The creep-resistant steel used is a highly resistant, water-quenched and then tempered close-grained structural steel with the following composition in wt.-% C 0.14-0.22 Cr 0.4-1.0 Mo 0.3-0.8 Ni 1.5-3.0 V 0.05-0.12 Mn 0.7-1.3 Pmax 0.015 Smax 0.003 Al 0.015-0.065 Si 0.20-0.60 Cumax 0.15 Nmax 0.012 Camax 0.004 the remainder being iron and impurities due to the production process.
