A high-temperature-resistant casting system comprises following casting elements in a connection relationship: a sprue cup (1) and a down sprue (2) connected with a lower end of the sprue cup, wherein the other end of the down sprue is connected with one end of a filtering element (6), the other end of the filtering element is connected with a three-way pipe (3), openings in two sides of the three-way pipe are connected with one end of an inlet section of a runner (4), and one end of an outlet section of the runner is connected with a tapered elbow (5). The casting elements comprise the following components in percentage by weight: 41-51% of a refractory fiber, 40-51% of a silicate fiber and 5-19% of a binder. A preparation method of the high-temperature-resistant casting system is further provided.

An amount of a halloysite clay, used as an additive in a foundry mix composition having a polyurethane-based binder system, reduces the amount of smoke emitted when molds and cores formed from the composition are exposed to molten metal, as compared to when the halloysite clay is not used.

A method of manufacturing a core for casting a component can include manufacturing a core for at least partially forming an internal passage architecture of a component with a material including radiopaque particles. A method can include removing a material including radio opaque particles from an internal passage architecture of a component; and inspecting the component via radiographic imaging at gamma/X-ray wavelengths to detect residual material. A core for use in casting an internal passage architecture of a component can include a material with radiopaque particles dispersed therein.
