Electrolytic treatment apparatus and method for continuously electrolyzing aluminium products.

摘要

An electrolytic treatment apparatus for continuously electrolyzing an elongated product of aluminum or an aluminum alloy at a low electrolyzing voltage and reduced amount of electric power. The apparatus includes at least one electrolytic section and front- and rear-side power supply section disposed respectively at front and rear sides of the electrolytic section in the longitudinal direction of the elongated product in the electrolytic section. Each of the power supply sections contains at least one electrode, and the electrolytic section contains a plurality of electrodes. The electrolytic section and the power supply sections are filled with an electrolyte in which the elongated product and the electrodes is immersed. A plurality of power sources are provided, with an electrode of the electrolytic section at a front-side portion thereof being connected to an electrode of the front-side power supply section through one of the power sources, and another electrode of the electrolytic section at a rear-side portion thereof being connected to an electrode of the rear-side power supply section through another of the power sources. The invention also provides an electrolytic treatment method by which the above apparatus is operated.
