Title:
【発明の名称】鋳造品の冷却を伴う清浄金属核生成鋳造装置及び方法
Document Type and Number:
Japanese Patent JP2003523829
Kind Code:
A
Abstract:
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; a nucleated casting system; and a cooling system 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.
