| Research Abstract |
n order to develop a new semi-solid continuous casting process of the aluminum alloys, which utilize the semi-solid slurries with homogeneous fine structures at the solidified states for controlling casting cracks generated often during the conventional continuous casting process, the semi-solid slurries with a fine structure of high strength 7075 and hypereutectic Al-Si type alloys were tried to manufacture by the rotational rotor treatment process previously developed. Semi-solid slurry with a considerably fine granular structure of 0.049mm in mean dia. was obtained in the high strength alloy. Semi-solid slurry of hypereutectic alloy had a fine structure with both homogeneously distributed primary Si particles of 0.014mm in mean size and partially existed granules of 0.037mm in mean dia., although the obtained volumes were small. By scaling up the rotor thickness, the required volume for continuous casting could be manufactured in the hypereutectic alloy.
