某酸轧机组在生产高硅双相钢时,轧制后表面有严重的条纹,导致冷硬卷降级。为确认条纹的来源和构成,利用表检仪、扫描电子显微镜和能谱仪进行了分析,结果表明,酸洗后带钢表面的条纹和热轧卷表面的红锈具有相似的成分构造和形貌,条纹处严重的氧化层在酸洗过程中无法彻底消除。 An acid mill in the production of high-silicon dual-phase steel, the rolling surface after the severe stripes, leading to the chill roll degradation. In order to confirm the source and composition of streaks, the results of surface inspection, scanning electron microscopy and energy dispersive spectroscopy were analyzed. The results show that the strip surface after pickling has the same composition and shape as the red rust on HRC surface Appearance, stripes at the serious oxidation of the pickling process can not be completely eliminated.
