摘要： PROBLEM TO BE SOLVED: To improve the quality of a thin product 1 by sufficiently suppressing the occurrence of defects such as shrinkage cavities in the surface of the thin product 1.
SOLUTION: A precise casting method comprises: a heating step where a ceramic mold 3 and a ceramic core 5 are heated; a pouring/solidifying step where, after the completion of the heating step, a molten metal M is poured into the ceramic mold 3 and solidified; and an exposure step where, after the completion of the pouring/solidifying step, the ceramic mold 3 and the ceramic core 5 are lost to thereby expose the outer surface and the inner surface of the thin product 1. In a meanwhile where the molten metal M is solidified in the pouring/solidifying step, in a state in which a cooling pipe 13 is inserted into a local space S on which radiant heat from the outer surface of the ceramic mold 3 concentrates, a cooling fluid is made to flow through the cooling pipe 13, thus the ceramic mold 3 is subjected to radiation cooling.

摘要： PROBLEM TO BE SOLVED: To provide a unidirectional solidification casting apparatus in which a boundary between a heating region and a cooling region is clear, and a temperature difference in the radius direction is eliminated upon heating and upon cooling.
SOLUTION: The central part of an external heating means 9 with a cylindrical shape is concentrically provided with an inner cylinder 8, and a cylindrical space 10 is formed between the inner cylinder and the external heating means. The required number of molds 23 can be stored in the space, and the molds are arranged in the circumferential direction at a ring-like mold support stand 22. The inner cylinder blocks passing of radiant heat from the external heating means through the central part. The mold support stand is elevated/lowered by an elevating/lowering apparatus, and the molds can be attached/detached to/from the space. Molten metal can be poured into the molds at an elevation position. The elevating/lowering apparatus lowers the molds into which molten metal has been poured, and the molten metal can be unidirectionally solidified.
