<P>PROBLEM TO BE SOLVED: To prevent a molten metal in a molten metal-feeding pipe from being oxidized. <P>SOLUTION: A method of feeding the molten metal includes a feeding step of flowing the molten metal 1 stored in a furnace 11 from an upper-end side opening portion of the molten metal-feeding pipe 12 by increasing the internal pressure of the furnace 11 inside which the molten metal is stored. In the feeding step, the variation ΔH of the liquid level of the molten metal 1 in the inside of the molten metal-feeding pipe 12 is 1-25% of the longitudinal dimension of the molten metal-feeding pipe 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
