板带热连轧中氧化铁皮的控制技术（Control technology of iron oxide sheet in hot strip rolling） February 2009 Vol. twenty-sixth, issue first Feb. 2009, Vol.26, No.1, rolled steel, STEEL, ROLLING Research and development Control technology of iron oxide sheet in hot strip rolling Liu Zhenyu, 1, Yu Yang 2, Guo Xiaobo 2, Guan Ju 2, Wang Guodong 1 (1. 、 State Key Laboratory of rolling technology and continuous rolling, Northeastern University, Liaoning, Shenyang 110004, china; 2. Anshan Iron And Steel Group Corporation, Liaoning, Anshan 114021) Abstract: the structure, composition and evolution law of surface oxide scale in hot strip rolling process are introduced Hot rolling, cooling and coiling techniques for low red iron oxide coverage. It is pointed out that the eutectoid reaction of FeO can be controlled by changing the coiling temperature after rolling Therefore, the iron oxide structure required for the acid washing or no pickling steel is obtained; the laminar cooling line is added to the front super fast cooling device to solve the oxidation problem comprehensively Sheet iron control and a better way to ensure mechanical properties of products. Key words: hot strip rolling; iron oxide sheet; composition; structure; acid washing CLC number: TG335. 55, document identification code: A, article number: 1003-9996 (2009) 01-0005-05 Techniques, of, Oxide, Scales, Control, during, Hot, Strip, Rolling LIU, Zhen-yu1, YU, Yang2, GUO, Xiao-bo2, GUAN, Ju2, WANG, Guo-dong1 (1, The, State, Key, Lab., of, Rolling, and, Automation, Northeastern, University, Shenyang 110004, China; 2, Anshan, Iron Steel, Group, Co., Anshan, 114021, China) Abstract:The, structure, evolution, rules, of, oxide, scales, during, hot, strip, rolling,, were, discussed.The, key, points For, the, control, of, oxide, during, hot, rolling, cooling, and, coiling, structures, were, demonstrated.The, eutectic, reac- Tion, kinetics, from, FeO, can, controlled, by, changing, the, coiling, temperature, and, the, be, oxide, struct
