摘要： The invention relates to a method for cooling blowing lances that, in order to treat liquid metal melts contained in metallurgical vessels, particularly a steel contained in RH vessels and optionally being subjected to a vacuum, and/or in order to heat metal melts (optionally under a vacuum), can be introduced into and withdrawn from the inside of the vessel by means of a lifting device. A blowing lance comprises at least one inner guiding tube, which serves to guide gases, particularly oxygen, and which has a head-end lance mouth for blowing the gas onto the metal melt, and comprises a cooling jacket, which extends over the length of the lance and which serves to lead a cooling medium therethrough. The cooling jacket is provided in the form of a double-walled jacket tube, which has an inner and an outer cooling channel and which is provided with a redirecting tube in the area of the head end. The metallurgical vessel is connected to a vacuum pump in order to lower the pressure. According to the invention, the instantaneously available suction capacity of the pump limits the maximum flow rate of the gas serving as the cooling medium.

摘要： A mounting enclosure (14) and an improved mounting arrangement for apparatus used in metal melting, refining and processing, particularly those apparatus adapted for steel making in an electric arc furnace (15), such as burners (10), lances and the like with supersonic oxygen lancing capability and injectors or the like for the introduction of particulate matter. The mounting enclosure (14) is fluid cooled to survive the hostile environment of the electric arc furnace (15) and is designed to occupy the step (24) between the side wall (12) and hearth (21) of the furnace (15) without any substantial change to the structure of the furnace (15). The mounting enclosure(14) comprises a plurality of fluid cooling conduits surrounding an apparatus aperture and an injector aperture which are formed through the enclosure (14) and adapted to mount an apparatus and an injector. The mounting arrangement includes utilizing the mounting enclosure (14) to mount an apparatus (10) with supersonic oxidizing gas lancing capability and an injector for particulate carbon in an electric arc furnace (15). Because the mounting enclosure (14) is approximately the width of the step (24), the discharge openings of the apparatus (10) and the injector are moved closer to the surface of the melt (18) and toward the center of the furnace (15) thereby providing increased efficiency. The discharge openings will now be extended to near the edge of the step (24) so that the oxidizing gas flow pattern of the apparatus (10) does not degrade the hearth material or other carbon flow pattern of the injector furnace equipment mounted nearby and the sufficiently agitates the slag (16) to produce foaming.

摘要： The invention relates to an exchange device for a blow lance (1) having a blowpipe (20) and a cooling jacket (30) surrounding the blowpipe (20) and through which coolant can flow, the inlet and outlet (34, 35) of which are arranged at the end of the blow lance (1) allocated to a coupling head (2). The coupling head (2) has an attachment (7) into which this end of the blow lance (1) can be introduced and comprises the connections (4, 12, 13) for the coolant inlet, coolant outlet and blower fluid supply. The blow lance (1) can be releasably coupled to the coupling head, where at least the inlet (34) or the outlet (35) of the coolant jacket (30) open on a circumferential surface of the blow lance (1) and where the connection (12, 13) allocated to the inlet (34) or the outlet (35) is arranged on a side surface of the attachment (7) allocated to the circumferential surface concerned. When the blow lance (1) is inserted into the attachment (7) of the coupling head, the blowpipe (20) is engaged with and tightly secured to a pipe union (6) of the attachment (7) which is connected to the blowing fluid supply. In addition, with the blow lance (1) inserted into the attachment (7) of the coupling head (2), a chamber (40, 41), especially an annular chamber, is formed in the region of the union (12) for the coolant supply and/or the union (12) for the coolant outlet.
