Abstract
Deoxidation casting machine, in which a deoxidizing compound reacts with a molten metal so as to deoxidize an oxide film formed on a surface of the molten metal. The machine includes a casting die having a molten metal inlet, a cavity into which a molten metal is poured from the molten metal inlet and a feeder head provided between the molten metal inlet and the cavity. A rate of cooling the molten metal in the feeder head is lower than that in the cavity.
