Abstract: A method for the casting of cast parts from an iron melt forming vermicular or spheroidal graphite, includes casting iron melt into a casting mold, which includes at least one casting mold part, which is formed from a mold material, which is mixed from a sand-type basic material and an organic binder, and then gassed with a gas containing sulphur in order to harden the binder, such that a mold part of stable form is obtained. The method provides embodiments in which molds produced in accordance with the SO2 process enable the risk of occurrence of local microstructure degeneration in the cast part to be reduced to a minimum. This is achieved in that, after the hardening of the mold part and before the casting, at least one of the surfaces, which comes into contact with the iron melt, is provided with a coating containing a non-volatile sulphide former.

Abstract: An aluminum casting process using a casting mold in which after the cavity (25) is filled with an inert gas, magnesium is introduced into the cavity to have a magnesium layer (58a) deposited on the cavity wall. Then, nitrogen gas is introduced into the cavity to form magnesium nitride (58b) on the surface of the magnesium layer after the cavity wall is heated to a specific temperature. Then, molten aluminum is supplied to have an aluminum casting molded, while the surface of the molten aluminum (39) is reduced with magnesium nitride. This makes it possible to form magnesium nitride within a short time and decrease the amount of nitrogen gas as required.

Abstract: A casting apparatus for performing a casting while an oxide film formed on a surface of a molten metal is reduced by allowing the molten metal and a reducing compound to be contacted with each other, includes: a molding die having a cavity for receiving the molten metal, a sprue from which the molten metal is poured and a feeder head portion arranged between the sprue and the cavity. A difference of heat insulation is partially provided between the feeder head portion and the cavity such that the molten metal filled in the cavity and the feeder head portion is sequentially solidified in a direction of from a terminal portion of the cavity to the feeder head portion.

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.
