Method for preparing semi-solid metal slurry, molding method, and molded product

Abstract

A manufacturing method of semi-solid metal slurry which pours a molten metal into a container to manufacture the semi-solid slurry, characterized in that a difference in height (H in ) between the molten metal and a bottom portion of the container is determined to be 3.5-fold or above of a diameter (D) of the container, and the molten metal is poured in such a manner that self-mixing occurs without requiring mixing from the outside.
