PURPOSE: To obtain a casting having high quantity and little porous holes by disposing plural radiating directional shields at a constant interval in a heating zone and reducing scattered heat radiation into a cooling zone.
CONSTITUTION: A die 6 in the inner part of a housing 2 is heated with heating elements 3a, 3b. The die 6 is placed on a cooling disk 5 and the cooling disk 5 is descended with an elevator device 16. Plural annular radiating directional shields 10 are vertically disposed to the longitudinal axis 13 of the die 6. These shields 10 obstruct the heat radiations S1, S2 and the heat ray is not reached to the portion B of the die 6 positioned in the cooling zone 11 and the temp. difference between a solid phase zone and a liquid phase zone, is increased. In this way, controlled solidified structure or crystallized structure can be prepared.
