摘要： A casting system comprises an off-center incoming source (300) of refined liquid metal that is provided to a casting (145) being formed by the casting system. The casting comprising a liquidus portion (148) that receives the refined liquid metal and a solidified portion, the casting further comprising a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free and segregation defect free. The casting system comprises a source of refined liquid metal, the refined liquid metal having oxides and sulfides refined out of the metal; and a nucleated casting system for forming the casting. The off-center incoming source of refined liquid metal is provided to the nucleated casting system off-set from a centerline (350) of the casting to disperse heat contained in the refined liquid metal throughout the liquidus portion thereby reducing a depth of the liquidus portion of the casting.

摘要： A casting system and method for producing a metal casting is provided. The metal casting can comprise a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state. The casting system can comprise an electroslag refining system (1); a nucleated casting system (2); and a cooling system (300) that cools the metal casting so as to cool a liquidus portion of the metal casting. The metal casting is cooled in a manner sufficient to provide a microstructure that comprises a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification from a liquidus state to a solid state.

摘要： Titanium is induction melted to produce a molten mass thereof and a water-cooled crucible (10) have a nonoxidizing atmosphere and a bottom opening (22). The current to the coil (30) used for induction melting is adjusted to produce a levitation effect on the molten mass (34) in the crucible (10) to prevent the molten mass (34) from flowing out of the bottom opening (22). The molten mass (34) is also maintained out-of-contact with the crucible (10) by providing a solidified layer (36) of titanium between the molten mass (34) and the crucible (10). After production of the molten mass (34) of titanium, the current to the induction coil (30) is reduced to reduce the levitation effect and allow the molten mass (34) to flow out of the bottom opening (22) of the crucible (10) as a free-falling stream (38) of molten titanium. The free-falling stream (38) from the crucible is directed to a tundish (48) from which the molten mass flows through a nozzle (54) for atomization. The spherical particles (42) produced by atomization are cooled to solidify them and are then collected.
摘要翻译：钛被感应熔化以产生熔融物质，以及具有非氧化气氛和底部开口的水冷坩埚（10）。调节用于感应熔融的线圈（30）的电流以对坩埚中的熔融物质产生悬浮效应，以防止熔融物质流出底部开口（22）。通过在熔融物料和坩埚之间提供凝固的钛层，熔融物质也保持与坩埚的不接触。在生产熔融物质的钛之后，减小到感应线圈的电流以降低悬浮效应，并允许熔融物质作为自由落下的熔融钛流从坩埚的底部开口流出。用惰性气体射流冲击该流以雾化熔融的钛以形成球形颗粒。将球形颗粒冷却以固化它们，然后收集。来自坩埚的自由流动的物流可以被引导到中间包，熔融物质从该中间包流过用于雾化的喷嘴。钛可以被熔化，以便在坩埚外形成熔融物质，然后将熔融物质引入坩埚中。

摘要： Casting systems and methods form a hollows metal casting, in which the hollows metal casting comprises a fine-grain, homogeneous microstructure. The microstructure is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state. The casting system (3) with for forming hollows castings comprises an electroslag refining system; a nucleated casting system (2) in which a casting is solidified; and a cooled mandrel (205) disposed at least in a liquidus portion (148) of the casting (145) in the nucleated casting system. The liquidus portion of the metal casting is solidified around the cooled mandrel in a manner sufficient to form a hollows casting with microstructure that comprises a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification from a liquidus state to a solid state.
