摘要: 针对某厂Q195冷轧镀锌带钢起皮缺陷, 应用金相显微镜、大样电解、扫描电镜及能谱分析对冶炼过程中各工序钢水内的大型夹杂物及显微夹杂物进行分析。结果表明, 冷轧缺陷主要是由于钢包卷渣和钢包耐火材料剥落所致。通过优化生产工艺及调整钢包浇注料材质等措施, 基本消除了冷轧带钢表面起皮和镀锌挂渣缺陷, 提高了镀锌板表面光洁度。

Abstract: In order to identify the reason forwrinkling defects at Q195 cold rolled galvanized steel strip,the large size and micro-size inclusions of samples taken from the various process steps of steelmaking had been characterized by utilizing large sample electrolysis,metallographic microscope,scanning electron microscope （SEM）. The results showed that the cold rolling defects are mainly due to the volume of ladle slag and ladle refractories caused by spalling was confirmed. By improving the process parameters and modify the ladle liner,wrinkling defects of cold rolled products were eliminated.
