    摘要: A method and apparatus for vacuum or air casting a molten superalloy, or other metal or alloy, containing an oxygen-reactive alloying element to form a cast part involves introducing the molten metallic material (melt) into a preheated mold having a melt reservoir, such as for example a mold pour cup, and gating for feeding the melt to one or more mold cavities. An induction coil disposed locally adjacent to the mold pour cup is energized in a manner to locally heat excess melt left in the melt reservoir to maintain it molten as the melt solidifies under vacuum or in air in the mold cavity to avoid shrinkage defects in the cast part.

    摘要: A fugitive pattern assembly is made by preforming one or more fugitive patterns of an article to be cast, placing the preformed patterns in an injection die, and injecting fluid gating material into the die to form gating connected to the patterns. The fugitive patterns are disposed in end-to-end and/or side-by-side relation and are interconnected by the gating.

    摘要: A multi-wall ceramic core for casting an airfoil with one or more internal cooling passages is made by preforming at least one fugitive core insert, then forming at least one core insert in-situ adjacent and fused to the at least one preformed core insert by introducing fluid fugitive pattern material into a composite core insert mold whereby the fugitive core inserts are integrally connected as a single composite core insert that includes features to form internal passage surfaces in the core when the composite core insert is removed. The composite core insert is placed in a core molding die cavity, and a fluid ceramic material is introduced into the die cavity to form the ceramic core body incorporating the fugitive composite core insert therein.

    摘要: Apparatus and method for use in firing a ceramic casting core includes a saggar and a core setter insert disposed in the saggar. The core setter insert can be disposed on a refractory particulate grog bed and/or refractory supports inside the saggar on a bottom wall of the saggar. The core setter insert has a core-receiving surface, which can have an airfoil shape to receive an airfoil-shaped ceramic casting core used in casting hollow airfoil castings.
