摘要： Method and apparatus for manufacturing an oxygen-free copper having an oxygen content of no greater than 3 ppm by weight are disclosed. In the method, a deoxidizing step is carried out by bringing a reducing gas containing hydrogen gas into contact with a molten copper to react to the oxygen to remove the same. Then a dehydrogenation step may be carried out by bringing a gas of lean hydrogen concentration into contact with the molten copper. Accordingly, the apparatus has a deoxidizing device for blowing the reducing gas into the molten copper and preferably a dehydrogenation device.
