摘要:
A levitation melting method and device through which a material having various configurations can be melted through efficient induction heating. First, a starting material(WB), whose outer diameter has been adapted to the inner diameter of a crucible(13), is inserted in crucible(13). The crucible(13) is shielded with argon gas, thereby starting the melting of the material(WB) to molten metal(WM). Subsequently, a suction tube(33) of a mold(31) is inserted into the molten metal(WM) for drawing a part of molten metal(WM) up into the mold(31) for casting. After part of the molten metal(WM) is drawn up, a sliding cover(15) is slid such that a material holder(19) is positioned right above the crucible(13). By opening a sliding plate(35) of the material holder(19), material pieces(WS) are inserted from the material holder(19) into the molten metal(WM) left in the crucible(13). Since gaps in the material pieces(WS) are filled with the molten metal(WM), a dense bulk is formed which is to be melted through induction heating.
