Abstract
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.
Claims12
A metallurgical vessel, e.g. a converter having a converter mouth, said metallurgical vessel being surrounded by a steel jacket, carried in a carrying ring, rotatable about a trunnion axis, provided with an expansion bearing and a tilt drive, the expansion bearing lying opposite the tilt drive, said metallurgical vessel being provided in zones of heavy thermal wear with a plurality of tubes through which a coolant flows, the tubes having a generally semicircular cross section and being welded to the jacket of the metallurgical vessel, one end of the series of tubes being connected to a coolant distributor and on the other end being connected to a coolant collector, a coolant-supply-conduit and a coolant-discharge-conduit being connected to said distributor and collector, respectively, wherein the improvement comprises a U-shape for the tubes, each U-shaped tube having its own separate base and leg sections, the tubes forming the legs of the U-shape being arranged side by side in the vertical direction with the base of the U-shape at one end when the vessel is in its operating position, said tubes being located along a generatrix of the jacket of the metallurgical vessel and the leg ends of one U-shaped tube being connected with the leg ends of the adjacent tube by connecting conduits.
Apparatus for cooling a metallurgical vessel with a metal jacket, e.g. a converter, comprising:
- a plurality of U-shaped tubes welded to the vessel jacket in zones of heavy thermal wear, each U-shaped tube having its own separate base and leg sections, said tubes having an open profile whose cross-section appears in the form of half a closed tube, the legs of the U-shaped tubes being arranged side by side in a generally vertical direction with the base at one end when the vessel is in its operating position, said tubes being located along a generatrix of the vessel jacket;
- connecting conduits for connecting the leg ends of each U-shaped tube with the leg ends of the adjacent tube;
- a coolant distributor means connected to one end of the plurality of tubes;
- a coolant collector means connected to the other end of the plurality of tubes;
- a coolant-supply conduit connected to said coolant distributor means for supplying coolant to said coolant distributor means so that coolant can be flowed through said tubes;
- and
- a coolant-return conduit connected to said coolant collector means for completing the flow path for the coolant in said tubes.
