摘要 |
A casting furnace for forming a large size turbine blade at a high casting rate using a casting alloy which has a single crystal structure or a columnar crystal structure, includes a main tank 2 in which a mold M is placed. A heater 6 heats the periphery of a mold M to a predetermined temperature.
