概要	Hollow AZ31B magnesium alloy pipe of 30mm in outer diameter and 10mm in inner diameter was made by vertical continuous casting using semisolid slurry prepared on an inclined cooling plate. The pipe could not be formed using a mold and a core rod without taper for forming the hollow because of the strong resistance between the mold and the semisolid slurry during casting. However, it was possible to make the pipe using both a taper mold and a core rod. Even so, the pipe surface appeared corrugated because the residual resistance between the mold and semisolid slurry influenced the pipe drawing. However, healing phenomenon occurred near the mold and core rod with heaters so that the remelted slurry was covered with the surface cracks. The distribution of the solid fraction in semisolid slurry inside the mold was evaluated by calculation.
