METHOD OF CASTING AND CASTING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2006/098382

Kind Code:

A1

Abstract:

Segregation is prevented in casting, e.g., a magnesium alloy containing additive elements or the like having a large specific-gravity difference to thereby obtain a cast of satisfactory quality. A casting mold (1) containing a metal melt placed therein is rotated in a certain direction on the vertical axis thereof as an axis of rotation with a rotator (7) for a given time while the metal melt is being solidified. After the given time has passed, the casting mold (1) is rotated for a given time in the direction opposite to that rotation direction. The normal/reverse rotation is repeated to solidify the metal melt. Thus, the metal melt is oscillated and stirred without ruffling the surface of the metal melt, whereby the melt in the casting mold can be made to have an even temperature distribution. Generation of precipitates by segregation is minimized and a fine homogeneous texture is obtained. Thus, a metallic material excellent in ductility and strength can be obtained.
