  • Apparatus for producing semi-solidified metal, method for producing semi-solidified metal, and semi-solidified metal
    Patent number: 9586261
    Abstract: An apparatus for producing a semi-solidified metal has a heating device which heats a metal material, a vessel, a cooling device which cools the vessel, and a pouring device which pours the metal material into the vessel. The vessel has a hollow member which configures a wall of the vessel and is opened at both of the upper and lower ends and into which the metal material is poured from the upper opening, and a bottom member which closes the lower opening of the hollow member and configures the bottom of the vessel. The cooling speed of the metal material by the bottom member is faster than the cooling speed of the metal material by the hollow member.

  • Molding apparatus, production apparatus of semi-solidified metal, production method of semi-solidified metal, and molding method
    Patent number: 9579716
    Abstract: An production apparatus of a semi-solidified metal has a vessel and a cooling device. The vessel into which a liquid-state metal material M is poured has a hollow member which is opened in up and down directions, and a bottom member which can close the lower opening of the hollow member and can be separated from the hollow member. The cooling device can cool the bottom member more than the hollow member.
