Device and method for manufacturing an active alloy

A method for manufacturing an active alloy, comprising:

• step A:
• placing a first active metal on a first bracket, and placing a second active metal on a second bracket, so as to make the first and second active metals located in a vacuum confined space of a melting chamber, wherein a melting point of the first active metal is greater than that of the second active metal;
• step B:
• vacuumizing the vacuum confined space of the melting chamber to below a pressure of 10−5 Torr, and lifting up the first active metal placed on the first bracket to a working area of an induction coil;
• step C:
• introducing inert gases of argon and helium, to prevent the first active metal from producing an oxidization reaction in a subsequent high-temperature process;
• step D:
• starting the induction coil, to make the first active metal in a levitation state and electromagnetically stirred and heated;
• step E:
• dropping the first bracket, to make the first active metal stably levitate and electromagnetically stirred and heated;
• step F:
• measuring whether the temperature of the working area of the induction coil reaches a predetermined temperature range, wherein the predetermined temperature range referring to a temperature range which has 80-480° C. less than melting point of the first active metal, to confirm whether the first active metal is in a half molten state;
• step G:
• when the first active metal is in the half molten state, dropping the second active metal placed on the second bracket to be added to the first active metal, and obtaining a homogenizing active alloy by means of electromagnetic stirring and heating;
• and
• step H:
• recycling the homogenizing active alloy automatically or manually, to accomplish a high vacuum crucibleless levitation melting process.
