    摘要： A method of refining a ferroalloy includes the step of blowing molecular oxygen or a gas mixture including molecular oxygen into a melt of the ferroalloy. A metallurgically acceptable particulate material is introduced from above into the melt. The particulate material is carried into the melt in a first supersonic gas jet which travels to the melt shrouded by a second gas jet.

    摘要： A metal making lance tip assembly including a tip face member having a plurality of outlets, a plurality of nozzles corresponding in number and in communication with the tip face member outlets, and a coolant flow baffle member for directing coolant flow around the nozzles. The lance tip assembly further includes both a generally centrally disposed coolant fluid diverting protrusion and a plurality of radial vanes at the inner surface of the lance tip face member, which vanes preferably extend essentially the entire axial distance between the inner surface of the lance tip face member and a lower surface of the coolant flow baffle member and essentially the entire radial distance from the central protrusion to an annular coolant fluid return passageway.

    摘要： A heat pipe assembly (10/110), under vacuum and having a working substance charged therein, comprising generally an evaporator (12/112) adapted to evaporate the working fluid and a condenser (16/116). The heat exchanging condenser is in fluid flow communication with the evaporator. The condenser is adapted to condense evaporated working substance received from the evaporator and has a reservoir (30/130), located at a higher elevation than the evaporator, for collecting liquid working fluid therein. A discrete, impermeable liquid return passage (36/136, 20/120) permitting the flow, by gravity, of the liquid working substance from the reservoir to the evaporator. The liquid return passage extends through the evaporator and terminates near the closed leading end thereof, and is fitted with a vent line (38/138) that diverts ascending vapor to the top of the condenser. A flow modifier (24/124) is positioned within the evaporator, causing swirling working fluid flow in the evaporator, whereby the flow modifier ensures that un-vaporized liquid entrained with evaporated working substance is propelled against inner surfaces (23/123) of the evaporator by centrifugal force to ensure liquid coverage of the inner surfaces, thereby delaying onset of film boiling.

    摘要： Metallurgical vessel for iron and steel making including a bottom portion, a sidewall and a lance arrangement of at least two lances for supplying oxygen containing gas to the interior of the vessel in operation. Each lance includes an end portion for emitting oxygen containing gas. The lance arrangement is configured so as to achieve in operation a substantially downwardly directed flow of post-combusted gases at the side wall of the vessel and a substantially upwardly directed flow of post-combusted gases in the center of the vessel.

    摘要： An injection lance to stir, trim and rinse a molten metal, such as liquid steel. A gas, or a gas and one or more powdered/granular metallurgical agents, may be introduced into the molten metal through the injection lance. The injection lance includes a plurality of interconnecting components. The components include at least one body section and one end section. Each section includes a center pipe and a refractory shell surrounding the center pipe. The body section(s) and end section provide a conduit for the gas or gas plus powdered/granular metallurgical agents. In a preferred embodiment, at least a portion of one of the refractory shells is made of a refractory composition that is isopressed around the center pipe.
