摘要： A system for wirelessly obtaining a measurement of a characteristic of a molten metal is disclosed. The system includes a contact block configured to be operatively coupled to a first end of a substantially hollow lance holder. The contact block is detachably and electrically coupled to and receives analog signals from a measurement sensor. The contact block converts the received analog signals into ultrasonic signals and transmits the ultrasonic signals through the hollow of the lance holder. A receiver block is configured to be operatively coupled to a second end of the lance holder. The second end is opposite the first end of the lance holder. The receiver block receives the ultrasonic signals from the contact block and converts the received ultrasonic signals into a digital voltage signal.

摘要： A multiple secured coupling device for oxygen lances 1 is achieved in that both the male connector 8 of the safety pipe 3, the connection part 18 of the lance holder 2 and also the cap nut 9 have an extending safety piece 10, 11. In this way, the male connector 8 can be inserted very far into the female part 19 or the connection part 18 and then located in position using the cap nut 9. A total of five sealing zones are created that in particular effectively prevent the escape of highly flammable gases, in particular oxygen.

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 electric arc furnace (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： 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 (66) acting between flanges (63,65) on tubular part (60) and tubular bracket (62), such that the forward end of part (60) is flush with the inner surface of the refractory lining (16b) of vessel barrel (16). On release of the clamping bolts and removal of a spacer ring (67) between flanges (63,65), lance (27a) can be driven inwardly for some distance by sliding within tubular bracket (62) to break slag accretions to permit withdrawal of the lance.
