ABSTRACT:
Provided is an apparatus for continuously manufacturing a plurality of high-quality billets containing fine, uniform spherical particles, with improvements in energy efficiency and mechanical properties, cost reduction, convenience of casting, and shorter manufacturing time. The apparatus includes a first sleeve; a second sleeve for receiving molten metals, one end of the second sleeve being hingedly connected to one end of the first sleeve at a predetermined angle; a stirring unit for applying an electromagnetic field to an inner portion of the second sleeve; a second plunger that is inserted into the other end of the second sleeve to define the bottom of the second sleeve for receiving the molten metals and to pressurize a prepared slurry; and a first plunger that is inserted into the other end of the first sleeve, the first plunger being operated in such a manner that when the second plunger pushes the slurry toward the first plunger, the first plunger is fixed in the first sleeve, and when a billet with a predetermined size is formed, the first plunger withdraws from the billet.
