ABSTRACT:
An oxygen lance tip or nozzle for Basic Oxygen Furnace Operations includes a body having an oxygen discharge means. The tip or nozzle is connected to a central oxygen pipe and two outer concentric pipes provide water inlet and outlet passageways communicating with an outer annular water chamber in the tip or nozzle. The tip or nozzle which may be a forging, includes water cooling channels individually isolated with respect to the central walls of the lance tip or nozzle, each of the channels being arranged in essentially a U-shaped configuration to provide a directional change of water flow from the water inlet passageway to the internal cooling area. Walls of the channels formed with essentially flat surfaces which consists of inserts or baffles supported on an outer ring which regulates by-passing water and separates the water inlet and outlet passages.
