3D temperature map reconstruction of a ceramic shell mold in investment casting process

This study analyzes the thermal behaviour of a ceramic shell mold during the a stage of the investment casting process. The investment casting process is a multi-step procedure which allows producing very reliable metal components such as turbine blades. Many parameters influence the final product of an investment casting process such as the initial mold temperature. This initial thermal status strongly affects the radiative heat transfer during the casting and, consequently, the product quality. This work describes and discusses the 3D temperature distribution over the ceramic shell mold of a turbine blade
