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 (21) of a sleeve (2) defined by first (31) and second (32) 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 (51), moving the first plunger toward the second plunger to compress the semi-solid metallic slurry and form a billet (52) via cooling, and shifting the billet toward the second plunger to discharge the billet from the sleeve.
