Patent number: 11162177Abstract: To prevent over-pickling during pickling pause, shorten the time required to switch between pickling operation and pickling pause, and heat acid solution efficiently, a pickling device includes: a pickling tank for storing acid solution and for pickling a steel strip by allowing the steel strip to travel therethrough while the steel strip is immersed in the acid solution; a heat exchanger for heating the acid solution in the pickling tank; a circulation tank for storing the acid solution, provided separately from the pickling tank; an acid-solution circulation device configured to circulate the acid solution between the pickling tank and the circulation tank; a control device configured to withdraw the steel strip from the acid solution; and a guide plate disposed in the pickling tank and configured to guide the acid solution circulated in the pickling tank by the acid-solution circulation device to the heat exchanger.Type: GrantFiled: February 22, 2017Date of Patent: November 2, 2021Assignee: PRIMETALS TECHNOLOGIES JAPAN, LTD.Inventors: Ryusuke Nakatsuka, Kosei Tsuji, Hideaki Suemori, Koichi Nakamura

Patent number: 9896755Abstract: The present invention is provided with: a duct of which one end interconnects to a wiping nozzle (22, 23) and the other end is open; a first valve (17) that controls the actual gas pressure (P1?) of the wiping nozzle (22, 23); a second valve (18) that controls the gas flow rate (Q2) dissipating to outside the system from another branched duct; a wiping pressure setting unit (11) that sets the set gas pressure (P1) of the wiping nozzle (22, 23); a first valve aperture setter (13) that sets the valve aperture of the first valve (17); a second valve aperture setter (14) that sets the valve aperture of the second valve (18); and a computation processing unit (12) that presents to the first valve aperture setter (13) the valve aperture at which the gas pressure (P1?) matches a set gas pressure (P1), and presents to the second valve aperture setter (14) the valve aperture at which the total gas flow rate (QT) supplied from a gas supply device (15) becomes uniform.Type: GrantFiled: February 10, 2015Date of Patent: February 20, 2018Assignees: PRIMETALS TECHNOLOGIES JAPAN, LTD., NISSHIN STEEL CO., LTD.Inventors: Hideaki Suemori, Masayoshi Tanaka, Norikatsu Kakemizu, Takashi Yamamoto, Hisao Morishita, Ryuuichi Yamashita
