Abstract: The present disclosure relates to the field of directional solidification, and in particular, to an apparatus, method, and process for directional solidification by liquid metal spraying enhanced cooling (LMSC). The process has the following beneficial effects: the apparatus of the present disclosure can regulate a solidification structure of a casting, refine a dendrite spacing, and reduce or avoid metallurgical defects, and can be used to prepare high-quality large-sized columnar/single crystal blades or other castings.
