Abstract
A twin roll casting machine that can reduce an amount of inert gas supplied. A duct is upwardly urged by cylinders to compress resilient sealing members respectively between a flange on a casting module and an upper flange on the duct and between a lower flange on the duct and a lower surface on a peripheral edge of an upper-end opening of an enclosure to maintain air-tightness of connections between the casting module and the duct and between the duct and the enclosure. A scrap box is moved upward by jacks to make a lower edge of a partition plate of an upper sealing member on the enclosure penetrate into the sealing material stored in a groove on the scrap box to maintain air-tightness of a connection between the scrap box and the enclosure.
