Abstract
The present invention provides a metal melting method for a manufacturing process of metal components having a desired shape, using metallic materials unaffected by oxygen and the constituent materials of the crucible. [Solution] In the manufacturing of a metal member, the first step is to prepare a crucible having an opening formed on its bottom surface to control the cross-sectional shape of the metal member to be manufactured; the second step is to bring the bottom surface of the crucible having the opening below the freezing point of the metal material constituting the metal member, thereby creating a melt-containing state in which the molten metal material is contained within the crucible; and the third step is to draw out the molten metal material from the opening in the melt-containing state so that a solid-liquid interface is formed inside the opening, thereby manufacturing a metal member whose cross-sectional shape is the shape of the opening. In this manufacturing method, the melt-containing state is achieved by using high-frequency induction heating to create the molten metal material, and the crucible is a double crucible or a crucible whose entire body is lined or coated with metal.
