To provide a casting method which removes metal oxide in a molten metal by titanium dioxide, and can more inexpensively improve the quality of a cast product with high efficiency, and to provide a casting device and a casting tool.
Regarding a melting furnace or a crucible 10 melting metals to be melted such as copper, aluminum and iron or their alloys, in the composition of a wall face with which at least the molten metal is contacted, titanium dioxide is incorporated. Titanium dioxide is incorporated at least into the composition of the surface of the material with which a molten metal is contacted, the molten metal is stirred and is uniformly contacted with the material into which titanium dioxide is incorporated, and casting is performed. The material comprising the metal to be melted such as aluminum, copper and iron is charged to the melting furnace 14, the material is heated to the melting temperature of the metal in a state where the material can be contacted with titanium dioxide and also under hardly oxidizable reaction where oxygen is intercepted, so as to produce a molten metal, and the molten metal is poured into a prescribed mold.
