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.

Abstract: Provided are a method and apparatus for continuously manufacturing quality billets for thixocasting that have a fine, uniform, spherical particle structure, in a short time, with improvements in energy efficiency and mechanical properties, cost reduction, convenience of casting, and shorter manufacturing time. The method involves applying an electric field to a domain of a sleeve defined by first and second plungers inserted through each end of the sleeve and loading a molten metal into the domain of the sleeve to form a semi-solid metallic slurry, moving the first plunger toward the second plunger to compress the semi-solid metallic slurry and form a billet via cooling, and shifting the billet toward the second plunger to discharge the billet from the sleeve.
