Abstract
The method of deoxidation casting is capable of deoxidizing the oxide film formed on the surface of the molten metal, improving wettability to inner faces of a cavity of a casting die, and casting high quality products with high casting efficiency. The method of deoxidation casting includes the steps of reacting a deoxidizing compound, which is made by reacting a metallic gas on a reactive gas, on a molten metal; and deoxidizing an oxide film on a surface of the molten metal.
