Abstract:
The present invention inhibits a cast object from having casting defects and makes the cast object have a fine crystal structure.
For producing a cast object (8) using a casting mold (10), a metallic material that forms free crystals (6) during solidification is melted first. Next, a melt (1) constituted of the molten metallic material is poured into the casting mold (10). In the casting mold (10), the melt (1) is solidified while free crystals (6) in the melt (1) are being accumulated on a surface (11) of the casting mold (10). Through the above steps, the melt (1) is solidified in the casting mold (10) to produce a cast object (8).
