Non-contacting side edge dam means for roll casting

摘要

An improvement in roll casting apparatus is disclosed which comprises side edge dam means for delivering a flow of gas toward the side edges of metal as it passes, from a source of molten metal, through a pair of opposing roll casting means to thereby contain the side flow of such metal during the roll casting operation. In a preferred embodiment, the gas is directed toward the cast metal through porous side edge dam means attached to a plenum which is inserted into the nip of the roll casting means.
