Abstract
A pulling-up-type continuous casting apparatus according to an aspect of the present invention includes a holding furnace that holds molten metal, and a shape defining member disposed above a molten-metal surface of the molten metal held in the holding furnace, the shape defining member being configured to define a cross-sectional shape of a cast-metal article to be cast as molten metal passes through an opening formed in the shape defining member. The opening is formed in such a manner that a size of the opening on a top surface of the shape defining member is larger than that on a bottom surface of the shape defining member. With this configuration, a cast-metal article having excellent surface quality can be produced even when molten metal is drawn up in an oblique direction.
