Title:
【発明の名称】鋳造品の液相線部分への補助冷却を具備した鋳造装置及び方法
Document Type and Number:
Japanese Patent JP2003521377
Kind Code:
A
Abstract:
A casting system with auxiliary cooling onto a liquidus portion of the casting can produce a metal casting that 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 with auxiliary cooling onto a liquidus portion of the casting can comprises an electroslag refining system as a source of liquid metal; a nucleated casting system; and at least one cooling system that supplies coolant onto a liquidus portion of the casting. The liquidus portion of the casting is cooled in a manner sufficient to provide a casting 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.
