Abstract
The mold includes a mold tube having pairs of parallel opposed outer surface portions which extend axially of the mold tube. The mold tube defines an axial casting passage having an inlet end for molten metal and an outlet end for a continuously cast strand of the metal. The mold tube is provided with internal concavities which are uniformly distributed peripherally of the casting passage. The internal concavities, which extend in a direction from the inlet end towards the outlet end, become smaller in this direction and are designed so that the strand is shaped as it travels along the casting passage. To form the mold tube, external concavities are impressed or cut in a tubular blank and a mandrel with external protuberances is then pressed into the blank. If necessary, the tubular blank can thereafter be drawn or otherwise processed to produce the desired outer contour of the mold tube.
