Abstract: A container for forming semi solid metal slurry, an apparatus for forming the semi solid metal slurry, a method of forming the semi solid metal slurry and the semi solid metal slurry provided to minimize mixing of the impurity generated with oxide or the air collection and to increase cooling speed and degree of super-cooling of the molten metal. A mold for manufacturing the semi-solid metal slurry comprises a container is a cup shape in which the top is open and have an inner side has + gradient about a bottom; a plate part(21) cover the opened top of the container and formed inlet ports(1) separately each other along the edge of the container; a cover(20) formed integrally a fence part(22) connected to the circumference of the plate part. The cover and the container are combined while and the top end portion edge of the container and the part in which the inlet port of the plate part is formed merging into each other. The top end portion edge of the container is partially exposed by the inlet port, and the area of the top end portion of the container, exposed by the inlet port, is 5~50% of the inlet port area.

Abstract: An apparatus for measuring a rotating speed of a melt is provided to control fine texture of materials by electromagnetic stirring and to design the materials optimally by clearly checking the rheological property of the material. In an apparatus(1000) for measuring a rotating speed of a melt, an EMS(Electromagnetic Stirring Device)(100) stirs the melt contained in a crucible(50) by applying an electromagnetic field to the crucible. A hall voltage measuring instrument(200) contacts with the melt and measures a hall voltage signal generated from the melt. A frequency detection system(300) measures driving frequency of the EMS. A lock-in unit(400) restores only a signal of a frequency range measured in the frequency detection system, from voltage signals detected by the hall voltage measuring instrument.
