鋳塊１０が得られる。In the apparatus shown in FIG. 1, after the pressure inside the vacuum container 1 is reduced by the vacuum pump 2, the molten metal flow rate adjusting rod 6 is moved to open the passage to the spray nozzle 4.
Due to the pressure difference between the inside and outside of the molten metal 8, the molten metal 8 reaches the atomizing nozzle 4, where it is atomized to form a fine metal powder 9. This fine metal powder 9 is sprayed into the mold 3 in a semi-molten state and solidified inside the mold to obtain a rapidly solidified ingot 10.
