【Abstract】 With the acceleration of digital transformation in the global manufacturing industry, precision casting of superalloys for aircraft engines has ushered in an era of digital and intelligent development. In order to achieve precision casting of superalloys with fewer defects, lower costs, and shorter production cycles, this paper proposes a new design concept for the integration of industrial Internet of Things and digital twins in key processes of superalloy precision casting based on the development and production practice of investment casting for superalloy structural components. This article elucidates the influencing factors of common quality problems such as solidification defects, dimensional deviations, and substandard microstructure and properties in the precision casting process of superalloys. Through digital solutions, the quality of superalloy castings can be improved, providing a reference for the digital transformation of the superalloy precision casting industry for aircraft engines.更多还原
