Abstract
A reduction casting method, in which a molten metal is poured into a cavity of a molding die and casting is performed while the oxide film formed on the surface of the molten metal is reduced by allowing the molten metal and the reducing compound to be contacted with each other in the cavity of the molding die, is characterized in that, at the time the molten metal is poured into the cavity, it is done while it is allowed to be in a turbulent flow.
