ABSTRACT:
The method of casting of the present invention is capable of making volume of a feeder head can be small and making cooling rate of the feeder head can be easily made lower than that of a cavity. The method is executed in a casting machine, which includes a casting die, in which the feeder head is provided between a metal inlet and the cavity and in which heat insulating of the feeder head is greater than that of the cavity so as to make cooling rate of the feeder head lower than that of the cavity. The method comprises the steps of: pouring a molten metal into the cavity; reacting the molten metal on a deoxidizing compound in the cavity so as to deoxidize an oxide film formed on a surface of the molten metal; and supplementing the molten metal in the feeder head to the cavity when the molten metal in the cavity is solidified and shrinked.
