摘要：In an apparatus for casting a metal comprise a crucible (), a casting mold () andan electrode rod () for an arc discharge are provided in an interior portion of a castingchamber () capable of controlling a pressure, a supporting shaft () exists in a side of an

outflow end portion of the crucible () close to a charging port () of the casting mold (),the crucible () can be tilted around the supporting shaft (), a crucible tilting means ()exists in a side of a non-outflow end portion of the crucible (), a clearance between ametal and the electrode rod is kept substantially constant after the arc melting of themetal () on the crucible () is started and the melting of the metal () makes progress anduntil the metal () in the melting state drops down due to the tilting of the crucible (), andthe arc discharge is kept during a period that the metal () flows and drops down. At thistime, it is preferable to connect a pressure reduction pump () and a pressurized gassupply source () to the casting chamber (), make a gas supply pressure Phaving acontrolled pressure larger than a gas pressure Prequired for casting, and shut off thesupply of the pressurized gas at a time of getting to the gas pressure P.
