PURPOSE: To obtain the molten metal casting the thin casting of high quality by providing the processing chamber equipped with the gas foam generating function for purifying a molten metal and molten metal agitating function between the holding chamber of the molten metal fed from a melting chamber and a pump-out chamber and arranging the molten metal flow-in port and flow-out port by their crossing.
CONSTITUTION: The preheating chamber 3 of a material, the melting chamber 5 melting the preheated material by a melting burner 4, the holding furnace 7 holding a molten metal (m) under heat reserving by a heat reserving burner 6, the processing chamber 8 executing the purifying treatment of degassing, etc., and the deoxidation of the molten metal (m) and the pump-out chamber 9 receiving the molten metal (m) of after processing are provided on the furnace body 2 of a holding furnace 11. A molten metal inlet port 15 and outlet port 16 are arranged in a crossing state to make the molten metal retentive. A purifier 17 is equipped with in the processing chamber 8, a hollow rotary shaft is driven by a driving motor 21 and the molten metal is agitated by an impeller 23. An inert gas is fed to the hollow rotary shaft 20 from a gas feeding source 26 and the inclusion in the molten metal is floated on the molten metal level. The optimum molten metal of high purifying degree for casting a thin casting of high quality can be obtd. with good yield.
