  • Patent number: 7661458
    Abstract: A magnesium metal thin plate manufacturing method includes at least a casting process of supplying a molten metal obtained by melting a magnesium metal to a molten metal bath, drawing out the molten metal, supplying the molten metal into the gap between a pair of casting rolls composed of at least a pair of casting upper roll and casting lower roll, applying pressure to the molten metal, and casting a plate solidified at a predetermined temperature and having a predetermined thickness, and a rolling process of rolling the cast plate by means of at least a pair of rolling rolls by applying pressure thereto to manufacture a magnesium metal thin plate. With the above arrangement, there can be provided a magnesium metal thin plate manufacturing method and manufacturing apparatus that can effectively manufacture a magnesium metal thin plate by plastic working without requiring a heat energy generation step again in rolling.
