Abstract (en)
The present invention relates to a casting method which employs rapid solidification of metal, rare-earth metal or the like, as well as to a casting apparatus and a cast alloy. A centrifugal casting method includes the steps of pouring a molten material onto a rotary body; sprinkling the molten material by the effect of rotation of the rotary body; and causing the sprinkled molten material to be deposited and to solidify on the inner surface of a rotating cylindrical mold. The axis of rotation of the rotary body and the axis of rotation of the cylindrical mold are caused not to run parallel to each other. The centrifugal casting method can attain a decrease in average deposition rate. As a result, generation of the dendritic ±Fe phase or generation of a segregation phase of Mn or the like is suppressed, thereby realizing a high-performance R-T-B-type rare-earth magnet alloy.
