METHOD OF PRODUCING CASTINGS WITH ORIENTED CRYSTALLIZATION AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

Abstract RU 2123909 C1

FIELD: metallurgy; may be used in casting of large blades of gas-turbine plants of various applications. SUBSTANCE: method includes melting and pouring of high-temperature alloy from melting crucible to hot ceramic mold. Melt in fine streams or drops gets through holes to mold hollow. After filling of mold volume by 2-9%, process of oriented crystallization is began. For this purpose, mold is lowered from zone of heating to zone of cooling. Dropwise or stream supply of melt eliminates mixing of melt before the front of crystallization and provides for obtaining qualitative structure. Excluded also is destruction of ceramic mold. EFFECT: higher efficiency. 5 cl, 6 dwg
