Method and apparatus for manufacturing semi-solid metallic slurry

Abstract

The present invention provides a method and apparatus for manufacturing a high-quality semi-solid metallic slurry containing fine, uniform spherical particles that can be readily and conveniently applied to a subsequent process, with improvements in energy efficiency and mechanical properties, cost reduction, convenience of casting, and shorter manufacturing time. The semi-solid metallic slurry manufacturing method includes applying an electromagnetic field to a space containing a slurry vessel, loading a molten metal into the slurry vessel in a state where the electromagnetic field is applied to the space, and drawing the slurry vessel out from the space. The semi-solid metallic slurry manufacturing apparatus includes at least one slurry vessel, at least one stirring unit having a space for the at least one slurry vessel and applying an electromagnetic field to the space, a driving unit moving the slurry vessel at least up and down to place the slurry vessel in the space, and a loading unit loading a molten metal in liquid state into the slurry vessel.
