Apparatus and method for use in firing cores

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 or supports 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.
