The invention relates to a metallurgical vessel, in particular to a converter, which in zones of heavy thermal wear, particularly between the carrying ring and the converter mouth, is provided with tube spirals flown through by a coolant. The tube spirals comprise open profiles or tube halves of semicircular cross section welded to the jacket of the metallurgical vessel. At one end the tube spirals are connected to a coolant collector and at the other end to a coolant distributor. The tube spirals have the form of a "U", wherein the tubes forming the legs of the U are arranged along the generatrix of the converter jacket and the leg ends of one tube spiral are connected with the leg ends of the following tube spiral by means of connecting conduits.
