Title:
吸引鋳造方法および装置
Document Type and Number:
Japanese Patent JP4445179
Kind Code:
B2
Abstract:
Countergravity casting of metals and metal alloys provides for melting of the metallic material under subambient pressure, evacuation of a gas permeable or impermeable mold under subambient pressure, and controlled, rapid filling of the mold while it is maintained under the subambient pressure by applying gas pressure locally on the molten metallic material in a sealed space defined by engagement of a mold base and a melting vessel with a seal therebetween. The gas pressure applied locally in the sealed space establishes a differential pressure on the molten metallic material to force it upwardly through the fill tube into the mold.
