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.
