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.
