Provided is a directional solidification casting apparatus capable of heightening a cooling effect when molten material poured in a mold is directionally solidified. A mold (20) disposed around a predetermined area is drawn out from a heating chamber (10) heated above a melting temperature of metals for producing a casting (31), and molten metals (32) held in a cavity (21) of the mold (20) are directionally solidified. The directional solidification casting apparatus (100) comprises a driving rod (42) by which the mold (20) is drawn out from the heating chamber (10), a gas nozzle (52b) through which a cooling gas is jetted from inside a predetermined area where the mold (20) is disposed so as to rapidly cool the mold (20), and a gas nozzle (52a) through which a cooling gas is jetted from outside the predetermined area where the mold (20) is disposed so as to rapidly cool the mold (20). A baffle (15) that does not move even when the driving rod (42) moves up and down is additionally provided. The baffle (15) blocks radiant heat emitted from the heating chamber (10).
A directional solidification casting apparatus for directionally solidifying molten metal supplied to a plurality of molds by drawing out the plurality of molds disposed around a predetermined area from a heating chamber heated at or above a melting temperature of the metal to be cast, comprising:
