摘要： A lance (10), for conducting a pyrometallurgical operation by top submerged lancing (TSL) injection, wherein the lance (10) has at least an inner pipe (12) and outer pipe (14) which are substantially concentric. The lower outlet of the inner pipe (12) is set at a level relative to the lower, outlet end of the outer pipe (14) required for pyrometallurgical operation. The lance (10) further includes a shroud (22) through which the outer pipe (14) extends and which is mounted on and extends along an upper portion of the outer pipe (14) to define with the outer pipe (14) a passageway (28) along which gas is able to be supplied for flow towards the outlet end of the outer pipe (14) for discharge exteriorly of the lance (10). The shroud (22) is longitudinally adjustable relative to the outer pipe (14) to enable substantial maintenance of, or variation in, a longitudinal spacing between the outlet ends of the shroud (22) and the outer pipe (14).

摘要： A TSL lance has an outer shell of three substantially concentric lance pipes, at least one further lance pipe concentrically within the shell, and an annular end wall at an outlet end of the lance which joins ends of outermost and innermost lance pipes of the shell at an outlet end of the lance and is spaced from an outlet end of the intermediate lance pipe of the shell. Coolant fluid is able to be circulated through the shell, by flow to and away from the outlet end. The spacing between the end wall and the outlet end of the intermediate pipe provides a constriction to the flow of coolant fluid to increase coolant fluid flow velocity therebetween. The further lance pipe defines a central bore and is spaced from the innermost lance pipe of the shell to define an annular passage, whereby materials passing along the bore and the passage mix adjacent to the outlet end of the lance. The end wall and an adjacent minor part of the length of the shell comprise a replaceable lance tip assembly.

摘要： A lance for conducting a pyrometallurgical operation by top submerged lancing (TSL) injection, has inner and outer substantially concentric pipes. The lower end of the inner or at least a next innermost pipe is set at a level relative to the lower end of the outer pipe required for the pyrometallurgical operation. The relative positions of the inner and outer pipes are longitudinally adjustable to enable the length of the mixing chamber to be maintained at a desired setting during a period of use to compensate for the lower end of the outer pipe wearing and burning back.
