Abstract
Arnold (13) includes a recessed portion (21) for receiving a melt (2). The recessed portion (21) is constituted by an inner wall surface (29) for converting the melt (2) into a solidified portion when the inner wall surface (29) contacts the melt (2), and opens in a withdrawal direction (D1) of the solidified portion. A curved line formed by a first contour (23p) and a second contour (25p) has a cusp at a position of start points (43 and 45). The distance between the first contour (23p) and the second contour (25p) in a width direction (D2) increases continuously from an upstream side to a downstream side of the withdrawal direction (D1). The shape of the inner wall surface (29) of the recessed portion (21) is determined so that a cast rod (3) can be rotationally displaced clockwise or counterclockwise about an axis passing through a first end point (33) or a second end point (35) and perpendicular to a section of the mold 13.
