Abstract: PURPOSE: To resolidify the casting material in columnar structure and prevent casting defect, by remelting the casting material in high pressure vessel, and then using heating zone with temperature gradient and high pressure, low temperature gas.  
     CONSTITUTION: A casting material 13a after precision casting is charged in a high pressure chamber 4 of high pressure vessel without separating from a ceramic mold 13b. Then, high pressure gas is charged through pipings 18, 14 and gas passage port 9. Operating all heating devices 8a to 8g capable of heating locally, the casting material 13a of processing 6 is induction-heated and remelted in the mold 13b. By stopping power supply sucessively in the upward direction from the heating device 8g in the lowest stage, the heating zone is changed sequentially in one direction. At the same time, the high pressure gas is discharged from the gas passage port 9 in the upper plug 2 through a pump 12 and a cooler 11, and is cooled in water through pipings 14, 15 and cooler 11 and is circulated into the high pressure vessel through the gas passage port 10 in the lower plug 3, so that the casting material 13a is cooled and solidified again from the lower part.
