Method and apparatus for directionally solidified casting
摘要：
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).
摘要（中）：

本发明提供一种定向凝固铸造装置，其能够在浇铸在模具中的熔融材料定向凝固时提高冷却效果。 设置在预定区域周围的模具（20）从用于制造铸件（31）的金属的熔化温度以上的加热室（10）被拉出，并且熔融金属（32）保持在 模具（20）定向凝固。 定向凝固铸造装置（100）包括：驱动杆（42），通过该驱动杆将模具（20）从加热室（10）中抽出;气体喷嘴（52b），冷却气体从预定 模具（20）设置为快速冷却模具（20）的区域，以及气体喷嘴（52a），冷却气体从设置有模具（20）的预定区域的外侧喷出，从而 快速冷却模具（20）。 附加地设置即使当驱动杆（42）上下移动时也不移动的挡板（15）。 挡板（15）阻挡从加热室（10）发射的辐射热。
