摘要:
The invention relates to a method for producing a mold tube made of copper or a copper alloy for a strand casting mold. A tube blank is formed on a mandrel by applying a force from the outside, said mandrel determining the inner shape of the mold, and the mandrel is removed from the mold tube (1, 1a) after the shaping process. The force is applied by moving the tube blank relative to a die that surrounds the tube blank. The die has a shaping structure for a cooling profiled section (6, 6a; 7, 7a) on the outer face (5) of the mold tube (1, 1a) so that the cooling profiled section (6, 6a; 7, 7a) is produced by means of the die while the tube blank is being shaped on the mandrel.

The present invention relates to a casting wheel (1) for producing strands of metals or metal alloys, said casting wheel (1) having a circumferential casting channel (2) which is bounded over a part length by a circumferential strip (11), wherein a foot (3) arranged beneath the casting channel (2) is provided to be cooled with a cooling liquid. The inner side (7), facing away from the casting channel (2), of the foot (3) has profiling (6) which has a profile height of 0.5 to 6 mm.
