ABSTRACT:
A melt is stored in a vessel placed in a decompression vessel. On the bottom of the vessel is arranged a bubble generator made of porous bricks, and bubbles of argon gas are introduced into the melt through this bubble generator. Also a lower half section of a degassing member is immersed in the melt. This degassing member has a cylindrical form with the lower end closed and the section immersed in the melt is made of a porous material permeable to gases and impermeable to melts.
With these features, a surface of molten metal can be put under reduced pressure and high content components of the melt can be removed by means of bubbling, and also solute components in the melt can be removed into bubbles of argon gas. Also, gases in the melt and gases produced by reactions between the melt and the porous material can be sucked through a wall of the degassing member into inside thereof and removed.
