Abstract:
    The method of the invention relates to the manufacturing of tubes of a continuously cast or the like billet by means of cold working, wherein the temperature of the material rises to the recrystallization range due to the influence of the deformation resistance. The method is particularly related to the further working of billets made of non-ferrous metals such as copper, aluminum, nickel, zirconium and titanium, as well as of their alloys.
