Abstract
A mold suitable for continuous metal casting comprising a cavity opened at both ends, in which a vertical cross sectional shape at the inner wall surface of the cavity from a meniscus position to a required region is formed as a restriction portion corresponding to the amount of shrinkage of a charged material from a liquid phase to a solid phase. This can prevent internal cracks at the corners of a cast product formed in the chilled layer. Then, a mold for use in continuous metal casting capable of coping with increasing casting rate is provided.
