    Abstract: Una lanza metalurgica (27a) para inyectar material particulado solido en un recipiente comprende un conducto central (31), a través del cual pasa el material particulado solido, y una camisa de refrigeracion anular internamente enfriada con agua (32) que rodea el conducto central. El conducto central (31) se mantiene separado dentro de la camisa de refrigeracion (32) por medio de una serie de abrazaderas separadoras (83) que se proyectan hacia fuera desde el conducto central para entrar en contacto con la periferia interna de la camisa de refrigeracion a fin de formar un pasaje de circulacion de gas anular entre el conducto central y la camisa de refrigeracion. Una entrada de gas de purga (85) en el extremo posterior de la lanza permite la admision de un gas de purga, como ser nitrogeno, en el pasaje de circulacion de gas (84) para que circule hacia delante por la lanza y salga de la lanza en el extremo delantero de la camisa de refrigeracion. El conducto central (86) está provisto de una proyeccion bulbosa (86) dentro del extremo delantero de la camisa de refrigeracion (32) para definir una boquilla de salida de gas estrechada (87).

    Abstract: Apparatus for injecting gas into a vessel including a gas flow duct 31 which receives hot gas through a gas inlet structure 32 at a rear end of the duct. An elongate central structure 33 extends throughout the length of duct 31 and carries a series of vanes 34 for imparting swirl to the gas flow exiting the forward end of the duct. The forward end of duct 31 has an internally water cooled tip 36 and water flows to and from tip 36 through annular passages 43, 44 in the wall of duct 31. tip 36 comprise a hollow shell internally divided by a partitioning structure to form a series of water flow galleries each extending circumferentially around the tip and interconnected for flow of cooling water sequentially through the galleries from the water supply passage 43 to the water return passage 44. The partitioning structure also provides a structural interconnection between inner and outer tubes 37, 39 of the duct wall to transfer gravitational load force from the inner tube to the outer tube when the apparatus is supported vertically through the outer tube.

    Abstract: Smelting apparatus comprises a vessel (11) and a solids injection lance (27a) extending through an opening in the wall of vessel barrel (16) into the interior space of the vessel. Lance (27a) includes a central core tube (31) through which to pass solid particulate material into the vessel and an annular cooling jacket (32) surrounding the central core tube (31) throughout a substantial part of its length. Lance (27a) has a mounting structure (61) comprising a tubular part (60) extended about cooling jacket (32) and about twice the diameter of the cooling jacket. Tubular part (60) fits within a tubular lance mounting bracket (62) welded to the shell (16a) of vessel barrel (16) to extend outwardly from the vessel. The lance is held within mounting bracket (62) by clamping bolts acting between flanges (63,65) on tubular part (60) and tubular bracket (62). Tubular part (60) is double walled and the interior space between its walls is divided into water flow passages through which cooling water flows from a water inlet (68) to an outlet (69).

    Abstract: An apparatus for injecting gas into a vessel is disclosed. The apparatus comprises a gas flow duct from which to discharge gas from the duct, an elongate central structure extending within the gas flow duct, and a plurality of flow directing vanes disposed about the central structure adjacent the forward end of the duct to impart swirl to a gas flow through the forward end of the duct. The apparatus also comprises cooling water flow passages in the vanes that have inlets at the forward ends of the vanes and outlets at the rear ends of the vanes.
