The invention relates to a shell of a ring-in-ring casting of K4169 high-temperature alloy. The shell comprises a shell surface layer and a multi-layer type shell back layer. The shell surface layer is formed by shell surface layer slurry and surface layer stuccoing materials in a solidification combination manner. The grain size of zircon powder for preparing the slurry as in the shell surface layer slurry ranges from 300 meshes to 1, 250 meshes. The aggregate of a surface layer stuccoing layer is the zircon powder, and the grain size of the aggregate ranges from 100 meshes to 150 meshes. Theshell back layer is formed by shell back layer slurry and back layer stuccoing materials in a solidification combination manner. The grain size of melted quartz powder and the grain size of melted quartz sand for preparing the slurry as in the shell back layer slurry range from 100 meshes to 1, 250 meshes. The aggregate of the back layer stuccoing layer is the quartz sand with the grain size ranging from 10 meshes to 50 meshes. Because the zircon powder is used as the surface layer slurry of the shell, and the melted quartz with an extremely small expansion coefficient is used as the back layer slurry, the coefficient of thermal expansion of an obtained shell is small, the grain size of used powder is strictly controlled, and the difference between the coefficient of thermal expansion ofthe shell surface layer and the coefficient of thermal expansion of the shell back layer is narrowed down.
