Abstract

An electromagnetic induction heat device to heat a first metal mineral stone and a second mineral stone to form a melting mixture liquid without stifling. The device keeps a temperature of the melting mixture liquid between solidus and liquidus of binary alloy phase diagram of the first and second metal mineral stone, then an alloy with solid state precipitates from said melting mixture liquid.

Claims (8)

1. An apparatus for manufacturing high-purity alloy, comprising:

a vacuum chamber including a feeding tube;

a first crucible disposed in the vacuum chamber;

an electromagnetic induction heat device surrounded the first crucible; and

a second crucible disposed in the vacuum chamber, and on one side of the first crucible.

2. The apparatus of claim 1 , wherein the top of said first crucible has a curved fringe for hanging.

3. The apparatus of claim 1 , wherein the top of said second crucible has a curved fringe for hanging.

4. The apparatus of claim 1 , further comprising a chilled plate deposes the bottom of said first crucible, and said chilled plate is designed to move up and down by a hoist mechanism.
