Abstract
A method of casting a semi-liquid or semi-solid iron-based alloy, the method including: applying, to a part or to the whole of an uppermost surface of an inner surface of a die, a lubricating die-release agent in which particles including at least one selected from molybdenum disulfide, graphite, tungsten disulfide, boron nitride, chrome oxide and boric oxide are dispersed in a solvent; and thereafter casting by using the die.

A method of casting a semi-liquid or semi-solid iron-based alloy, the method comprising:
- applying, to a part or to the whole of an uppermost surface of an inner surface of a die, a lubricating die-release agent in which particles including at least one selected from molybdenum disulfide, graphite, tungsten disulfide, boron nitride, chrome oxide and boric oxide are dispersed in a solvent;
- and
- thereafter casting by using the die.
A die for casting which is used for semi-liquid casting or semi-solid casting of an iron-based alloy,
- wherein a lubricating die-release agent in which particles including at least one selected from molybdenum disulfide, graphite, tungsten disulfide, boron nitride, chrome oxide and boric oxide are dispersed in a solvent is applied to a part or to the whole of an uppermost surface of an inner surface of the die.
