Abstract
Molten metal is supplied to a pouring basin formed between cooling members, such as movable cooling drums. A closed space is formed at a meniscus area whereat any one of the cooling members starts to come into contact with the molten metal, and a soluble gas or a mixture of soluble and insoluble gases is supplied to and filled in the closed space, thereby covering the meniscus area with the gas or the mixture. This arrangement enables a continuous casting of a thin metal sheet without surface cracks and having excellent surface characteristics.
