Apparatus and method for continuously electrolyzing aluminum products

An electrolytic treatment method for continuously electrolyzing an elongated product of aluminum or an aluminum alloy, comprising the steps of:

• passing said elongated aluminum product successively through a front-side power supply section, ann electrolytic section, ad a rear-side power supply electrode and said electrolytic section containing a plurality of electrodes, each of the electrolytic section and said power supply sections containing separate sections of an electrolyte in which said elongated product and said electrodes are immersed;
• applying a first electric current from a first power source between an electrode in said and electrolytic section at a front-side portion thereof and an electrode in said front-side power supply section;
• and applying a second electric current from a second power source between an electrode of said electrolytic section at a rear-side portion thereof and an electrode of said rear-side power supply section, said first and second electric currents flowing in opposite directions through said elongated product.

An electrolytic treatment apparatus for continuously electrolyzing an elongated product of aluminum or an aluminum alloy, comprising:

• at least one electrolytic section,
• front-side and rear-side power supply sections disposed respectively at front and rear sides of said electrolytic set in the longitudinal direction of the elongated product in said electrolytic section, each of said power supply sections comprising at least one electrode and said electrolytic section comprising a plurality of electrodes,
• a plurality of power sources, wherein a first electrode in said electrolytic section at a front-side portion thereof is connected to an electrode of said front-side power supply section through one of said power sources and generates a first electrical current through the elongated product, and a second electrode in said electrolytic section at a rear-side portion thereof is connected to an electrode of said rear-side power supply section through another of said power sources an generates a second electrical current through the elongated product, said first and second electrical currents flowing in opposite directions through said elongated product.
