ABSTRACT:
Chill-cast metal foil is produced by an apparatus having a flexible gas permeable valve which provides a means for retaining the molten metal prior to processing it into a chill-cast metal foil and simultaneously providing a gas purging of the reservoir and the orifice in the reservoir to prevent formation of detrimental oxides of the molten metal by the exposure of the molten metal to air or oxygen containing atmosphere.
A method for producing the chill-cast foil is also described.
