COLD CRUCIBLE MELTING CASTING DEVICE
Document Type and Number:
Japanese Patent JP2003065679
Kind Code:
A
Abstract:
To permit the increase of the melting amount of a metal, and the meltage of a metal heavy in a specific gravity and high in a melting point, by reducing the contact of a melting metal with a water-cooled metallic crucible through the side surface as well as the escape of heat into the water-cooled metallic crucible.
Coils are provided around the outer periphery of the water- cooled metallic crucible 1 in up-and-down two stages while the frequency of an electric current, conducted to flow through an upper coil 2a, is specified so as to be lower than that of a current, conducted to flow through a lower coil 2b.
