Title:
【発明の名称】チキソトロピ金属スラリを磁気的に攪拌する方法及び装置
Document Type and Number:
Japanese Patent JP2003534920
Kind Code:
A
Abstract:
A method and apparatus (10) for stirring a molten thixotropic aluminum alloy (11) comprising a first solid particulate phase suspended in a second liquid phase so as to maintain its thixotropic character by degenerating forming dendritic particles into spheroidal particles while simultaneously equilibrating the melt temperature by quickly transferring heat between the melt and its surroundings. The melt is stirred by a magnetomotive force field (30, 32, 34) generated by a stacked stator assembly (12). The stacked stator assembly (12) includes a stator ring (24) adapted to generate a linear/longitudinal magnetic field (34) positioned between two stator rings (20, 22) adapted to generate a rotational magnetic field (30, 32). The stacked stator rings (20, 22, 24) generate a substantially spiral magnetomotive mixing force and define a substantially cylindrical mixing region therein.
