从热轧工艺角度对超低碳IF钢热轧卷表面卷渣、面翘皮缺陷进行分析，研究了不同热轧工艺参数对该类缺陷的影响规律。研究结果表明：卷渣、面翘皮缺陷发生率随入炉温度升高而降低，随在炉时间加长，缺陷发生率降低。卷渣及面翘皮缺陷随出炉温度的增加基本呈现发生率下降的趋势，但从Minitab数据分析显示出炉温度影响不大。入炉温度和在炉时间对卷渣、面翘皮缺陷影响更大。
The slag entrapment and surface sliver defects were analyzed from the perspective of the hot rolling process for ultra-low carbon IF steel,the influences of different hot-rolling parameters were studied. The results show that the slag entrapment and surface sliver defects reduce with the increase of the hot charging temperature. A reduced incidence of slag entrapment and surface sliver defects happens with increasing holding time and lowering tapping temperature,but Minit-ab data analysis shows that this parameter has little influence. The hot charging temperature and the holding time in the re-heating furnace have greater impact.
