摘　　要：针对冷轧酸洗钢板黑斑缺陷问题,对Q195、STl3钢在不同试验温度下进行了氧化铁皮的生成、冷却、酸洗试验,对试验后的试样和生产现场钢板的表面进行了微观分析。结果表明:冷轧酸洗钢板黑斑实质上是未完全酸洗掉而残存的氧化铁皮,是由热轧工艺引起;冷轧酸洗钢板黑斑主要由Fe3O4和FeO组成;温度越高,表面氧化铁皮越厚,Fe3O4含量越高,冷轧酸洗钢板越易产生黑斑。Oxide scale formation during cooling and pickling of Q195 and ST13 steel sheets at different temperature were studied to study the black spots on cold rolled pickled steel sheets.The surface of tested Q195 and ST13 steel sheets and samples taken on site were analyzed.The results showed,the black spots are in fact the oxide scale formed during hot rolling and remained after pickling;the black spots are primarily composed from Fe3O4 and FeO;and the higher the temperature,the thicker the scale is,the higher the content of Fe3O4 is,the easier the black spot formation is.
