柳叶状氧化铁皮的形貌演变及控制方法

Morphology evolution and control method of willow leaf scale

本文从缺陷的形状、颜色、触感等多个角度入手,按照热轧、酸连扎、退火的顺序详细介绍了热轧后、酸轧后、退火后柳叶状氧化铁皮的缺陷特征;为了确保缺陷形貌演变准确,利用表面检测设备对柳叶状铁皮进行各个工序的追踪,利用电镜设备对各个位置的铁皮进行光谱成分分析,精准推断出了柳叶状氧化铁皮缺陷的形貌演变。使用显微镜观察铁皮缺陷的微观形貌,从形成机理上确定铁皮缺陷的产生原因,并依据以往的生产经验从热轧和酸连轧工序入手确定柳叶状铁皮的控制方法。

In this paper,the defect characteristics of willow leaf-like oxide sheet after hot rolling,acid rolling and annealing are introduced in detail from the perspectives of shape,color and touch.The surface inspection equipment was used to track the various processes of the willow leaf-like iron sheet,and the electronic microscope equipment was used to analyze the spectral composition of the iron sheet at each position to ensure the accuracy of defect evolution.The microscopic morphology of iron sheet defects was observed by microscope to determine the cause of iron sheet defects.According to the previous production experience,the control method of willow leaf iron sheet is determined.
