Abstract: A method for producing a mold tube from copper or a copper alloy for a continuous casting mold, a tube blank being formed on a mandrel, which determines the inner shape of the mold, by the external application of force, and, following the shaping process, the mandrel being removed from the mold tube (1, 1a); the action of force resulting in response to the movement of the tube blank relative to the die surrounding the same; the die having a shaping structure for a cold formed profile (6, 6a; 7, 7a) on the outer surface (5) of the mold tube (1, 1a), so that the cold formed profile (6, 6a; 7, 7a) is produced by the die upon shaping of the tube blank on the mandrel.

Abstract: A permanent chill mold for the continuous casting of metal, having a mold cavity (2) which has a pouring slot (3), an exit opening (4) and a casting cone (6). At least one concave bulging (7) is provided that extends in the casting direction (G), which begins at a distance (A) below a predetermined casting bath level position (5) and extends up to the exit opening (4).

Abstract: A permanent chill mold for the continuous casting of metals. At least one partial region of the outer surface of the permanent chill mold (1) is provided with cooling channels (2, 2a, 2b, 2c). The depth and/or the width of the cooling channels (2, 2a, 2b, 2c) are greatest in the middle of a sidewall of the permanent chill mold (1), and they decrease in the direction of the corner region (4) of the sidewall. Because of this, a uniform heat dissipation can be implemented, and thereby higher casting speeds are possible.
