摘　　要：介绍了板带热连轧过程中表面氧化铁皮的结构、组成和演变规律,提出了有效抑制氧化铁皮生长、降低红色氧化铁皮覆盖率的热轧、冷却和卷取技术路线。指出通过改变轧后卷取温度,可以控制FeO的共析反应,从而获得"减酸洗"或"免酸洗"钢需要的氧化铁皮结构;层流冷却线增加前置超快冷装置是综合解决氧化铁皮控制和产品力学性能保证的较佳途径。The structure,evolution rules of oxide scales during hot strip rolling were discussed. The key points for the control of oxide structures during hot rolling,cooling and coiling were demonstrated. The eutectic reaction kinetics from FeO can be controlled by changing the coiling temperature,and the oxide structures of free pickling can be obtained. Finally the author pointed out the super-ACC equipment setting in front of laminar cooling line was the optimal measure to control oxide scales and mechanical properties of product.
