Title:
液体金属の離心供給源を備える鋳造装置及び方法
Document Type and Number:
Japanese Patent JP4959897
Kind Code:
B2
Abstract:
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.
