Molten metal supply cylinder, molten metal supply apparatus incorporating such a supply cylinder and molten metal supply method

摘要

A molten metal supply cylinder for melting a low melting point metallic material in a solid phase and supplying the molten metal material, including a melting section to be directly or indirectly brought into contact with a low melting point metallic material to produce molten metal, and a substantially tubular flow path that has a first opening formed at an end thereof in the melting section and a second opening at the other end thereof and allows the molten metal produced in the melting section to flow. An oxide of the surface layer of the low melting point metallic material is removed by an oxide removing section before the low melting point metallic material is molten in the melting section.
