Abstract
An apparatus for continuous electrolytic treatment of an article of aluminum web or an aluminum alloy including an electrolytic part, a pre-stage power supply part provided upstream of the electrolytic part, a post-stage power supply provided, downstream of the electrolytic part and a power source, at least one electrode in the pre-stage power supply part and at least one electrode in the post-stage power supply part part being connected with one pole of the power source, and at least one electrode of the electrolytic part being connected with the other pole of the power source. This apparatus can decrease a running cost such as the electric cost and the cooling cost as well as the facilities cost, can conduct a high speed treatment and increase the thickness of a film without fusing an aluminum article, even if the aluminum article has a small sectional area, such as a wire, a foil or a thin web. The electrolytic treatment can stably continue without preparing some means for preventing corrosion, leakage and the like at the time that the line is speeded up and the thickness of the film is increased.
