Abstract
An open topped, refractory lined metallurgical converter vessel has a metallic shell. A cooling jacket is affixed to the frusto-conical nose portion of the shell and comprises a plurality of right angle members affixed to the shell in a side-by-side relation and extending generally in the axial direction. The members have their edges affixed to the shell surface to form a flow passage therewith. A manifold pipe extends partially around the vessel and is connected to all of the flow passages except for those above and adjacent to the tap nozzle which are connected to a drain manifold. Plate sections are affixed to the upper end of the angle members and to the shell to define a nose cooling ring which is connected to the upper end of each angle section to define a return flow path for cooling water. Baffles are disposed in the nose cooling ring adjacent the margins of the angle members which are connected to the drain manifold to insure filling of the system.
