Numerical Simulation for Optimizing Temperature Gradients during Single Crystal Casting Process

Abstract

This article describes application of computational simulation for manufacturing of castings using investment casting technique. A mathematical model was created describing the process of melted metal pouring into the ceramic shell with its further solidification. Using this model the process of manufacturing single-crystal patterns from heat-resistant nickel superalloy was simulated. The obtained computational model was verified by the temperature measuring of the real-life production experiment. Using mathematical simulation the speed of the patterns moving out was optimized to increase temperature gradient on the casting.
