Abstract:
A method of deoxidation casting, comprising the steps of:pouring a molten metal into a cavity of a casting die, which includes a feeder head provided between a molten metal inlet and the cavity; and reacting a deoxidizing compound with the molten metal so as to deoxidize an oxide film formed on a surface of the molten metal, characterized in, that rate of cooling the molten metal in the feeder head is lower than that in the cavity, that the molten metal in the feeder head, which is not solidified, is moved when the molten metal in the cavity is solidified so as to make an outline of a cast product correspond to that of a desired product; and that the molten metal in the feeder head, which is not solidified, is removed from the cast product solidified in the cavity.
