    摘要: A lance holder characterized by a high degree of safety is equipped with a mounting or a pipe fixing, which safely prevents a rotation even of a bent lance pipe in the lance holder. The clamping head has a fixing part and a clamping part which ensure a punctiform fixation by way of displaceable pressure elements, particularly in the form of spheres. At least three such spheres are disposed across the circumference in a distributed manner, and ensure the safe fixation across a large tolerance range with regard to the dimensions of lance pipes. Said large tolerance region is further secured in that sealing sleeves having a larger inside diameter may be used, since the same are no longer deformed in the longitudinal direction in order to provide the seal, but instead are deformed in the radial direction. In summary the high degree of operational safety is also completed by the association of a chip and/or attachment of a nanocoating.

    摘要: An apparatus for injecting gas into a vessel includes a gas flow duct which receives hot gas through a gas inlet structure at a rear end of the duct. The forward end of the duct has an annular duct with an internal cooling water passage. Cooling water supply and return passages are formed within the wall of the duct such that water flows to and from a tip through the supply and return passages. The tip includes a hollow shell and a partitioning structure that has a ring and a plurality of circumferential flanges that project outwardly from the ring to the shell 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 passages to the water return passage. The circumferential flanges also serve as buttress supports for the shell.

    摘要: 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.

    摘要: An enclosure for mounting burners and particle injection equipment in an EAF is described. The enclosures are mounted on the sidewalls of an EAF and include passages in which burners or injectors are mounted so that the discharge ends of the burners and injectors are located closer the melt than sidewall mounted burners and injectors. Burners and injectors mounted in the enclosures heat material in the furnace and deliver particulates to the melt more efficiently than conventionally mounted burners and injectors. The enclosures are liquid-cooled, typically by water, and constructed of high conductivity materials such as copper and/or cast iron and can be constructed in one or more pieces. Therefore, the enclosures protect the burners and injectors from the excessive heat and mechanical impact to which they would normally be subjected when mounted so close to the melt.

    摘要: A device for coupling a blow lance with a header is disclosed, in which the force required for producing a sealing joint between the header (2) and the lance (4) is exerted by a cooling fluid and/or a blowing fluid. In a preferred embodiment, said cooling fluid and/or blowing fluid acts via a pressure surface (32) on the joint between the header (2) and the lance (4), the pressure surface being integral with a piston (22) which transmits the pressure to said joint. The lance has preferably a first coupling surface (12), while the header (2) has a second coupling surface (14), and one of said coupling surfaces (12 or 14) is integral with said piston (22).
