A
Design Study in Nickel-Based Superalloy Castings-- Combustor Floatwall Panel
The Casting Design Issues
The
casting design engineers at the Hitchiner Manufacturing, Gas Turbine Division, had three
imperatives for an integrated casting design.
Design for Performance
Design for Manufacturability/Castability
Design for Cost
Critical Casting Design Issues --The
requirements for performance, manufacturability/ castability, and cost are closely
interconnected. Four casting design issues played a major role in meeting the three design
imperatives
Select the molding process to produce the precision features and meet
tolerances
Choose the casting process to insure alloy quality and control costs.
Develop the mold configuration to optimize metal flow and maximize loading
