Verfahren zur Herstellung von Halbzeug aus Kupfer durch Angiessen

摘要

Dip-formed copper rod produced by drawing a core rod upwards through a crucible of molten copper so that copper adheres to the core is partially cooled and then hot worked to a reduced diameter before cooling to below the temperature of atmospheric oxidation. The whole process is conducted in a protective atmosphere of hydrogen and nitrogen mixed. Advantageously hydrogen does not exceed 15% by volume and the mechanical working is carried out in a temperature range of 650-950 degrees C.
