Abstract
A permanent magnet-type molten metal stirring device includes: a support body that can suppress heat transfer from molten metal; a magnetic field unit provided above the support body and including a permanent magnet allowing magnetic force lines to vertically extend in the molten metal; and a drive unit provided below the support body and driving the molten metal with an electromagnetic force generated by the magnetic force lines and current allowed to flow through the molten metal by the drive unit. The drive unit includes: a cylindrical drive main body mounted on a lower portion of the support body and including a passage formed therein and laterally extending in a longitudinal direction, and a pair of electrodes provided at positions opposed to each other along a width direction via the passage, the pair of electrodes allowing current intersecting the magnetic lines of force in the molten metal.
