Patent number: 6726830Abstract: This invention relates to an improved apparatus and method for electrolytic descaling of steel strips. The apparatus comprises electrodes integrated with nozzles having jet openings for dispensing electrolyte onto the surface of the steel strips. By jetting the electrolyte to the steel strip in the air and applying a voltage to the electrode, the scale on the surface of the steel strip is removed. This jetting of electrolyte reduces the size requirement of the electrolyte tank storing the electrolyte because the required quantity of electrolyte decreases. The present invention does not require immersion of the electrodes in the electrolyte and thus avoids the problem of short-circuiting that occurs with submerged electrodes. This results in a significant improvement in electric power efficiency.Type: GrantFiled: October 18, 2001Date of Patent: April 27, 2004Assignee: Hitachi, Ltd.Inventors: Katsumi Mabuchi, Tomoko Kikuchi, Yasunobu Kani, Tsuneo Nakamura, Shinichi Yokosuka

Patent number: 5463801Abstract: A coating system and method of using same for coating a hot rolling strip coil, such as zinc coating of steel strip, is disclosed. The coating system includes sequentially arranged coil uncoilers, a strip welder, a pickling tank, a heating and deoxidizing furnace, a coating pot, and a coiler. A rolling mill with at least one cold rolling mill stand is interposed between the pickling tank and the heating and deoxidizing furnace. In certain operations with hot rolling strip coil having a larger than desired thickness, the cold rolling mill is operated to reduce the strip material thickness. In operations where the strip material is of proper desired thickness, the strip material is passed through the cold rolling mill without carrying out cold rolling. The system and method accommodate a single coating line usable with a wide variety of hot rolled strip material and finish coated material thicknesses.Type: GrantFiled: February 23, 1994Date of Patent: November 7, 1995Assignee: Hitachi, Ltd.Inventors: Toshiyuki Kajiwara, Teruo Yamagushi, Hitoshi Okoshi, Tsuneo Nakamura
