Abstract: A smelting apparatus includes a vessel and a solids injection lance extending through an opening in the wall of a vessel barrel into the interior space of the vessel. The lance includes a central core tube through which to pass solid particulate material into the vessel and an annular cooling jacket surrounding the central core tube throughout a substantial part of its length. The lance has a mounting structure including a tubular part extended about the cooling jacket and about twice the diameter of the cooling jacket. The tubular part fits within a tubular lance mounting bracket welded to the shell of the vessel barrel to extend outwardly from the vessel. The lance is held within the mounting bracket by clamping bolts acting between flanges on the tubular part and the tubular bracket.

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: Apparatus for injecting as 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 the 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. Vanes 34 are mounted on central structure 33 so as to extend to forward ends disposed within the duct tip 36 and are dimensioned such that during operation of the apparatus their forward ends are engaged and supported by the internally water cooled duct tip 36.

Abstract: A metallurgical vessel (11) has circumferentially spaced tubular mountings (25) through which to extend solids injection lances (31) into the vessel. Lance extraction apparatus (33) comprises an elongate track support structure (41) supporting a twin rail track (40) inclined upwardly and outwardly from the vessel above the direction of inclination of a respective lance (31). Interconnected upper and lower carriages (42, 44) are moveable along track (40) by operation of a hoist (47). Extraction apparatus (33) is operable sequentially to remove solids delivery line sections (36) and (37) and the lance (31) by connection to the carriages (42, 44) and upward movement of those carriages along track (40). Upper carriage (42) carries a pivot arm (51) for connection to upper parts of components to be removed such that those components can be pivoted downwardly to positions in which they can be hung from an overhead crane for removal to a remote location.

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).
