ABSTRACT:
In the method of deoxidation casting, a disused metal left in a feeder head can be easily removed from a cast product, or the molten metal left in the feeder head can be removed from the cast product so as to easily finish the cast product. The method comprises the steps of: pouring a molten metal into a cavity of a casting die; and reacting a deoxidizing compound with the molten metal so as to deoxidize an oxide film formed on a surface of the molten metal. And the method is characterized in that rate of cooling the molten metal in a feeder head of the casting die is lower than that in the cavity, and that the molten metal in the feeder head, which is not solidified, is treated 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.
