针对某厂DMS森吉米尔轧机生产无取向硅钢表面麻面缺陷的问题，根据生产实际，对其形成原因从乳化液及工作辊两方面因素进行了分析。结果表明：乳化液对麻面缺陷的产生有一定影响，但不是主要因素，主要原因是由于二十辊森吉米尔轧机工作辊辊径较小，轧制相同长度带钢轧辊运转周期较大，容易产生疲劳失效而导致。为此，提出通过调整冷轧工序成品轧制道次的压下率以减小轧制力，从而减小工作辊的磨损疲劳；通过对轧制乳化液浓度、温度的合理控制，以改善润滑效果、提高轧制速度，而进一步缓解轧辊疲劳的改进措施，使该钢厂无取向硅钢麻面缺陷发生率由原来的18%降至0.8%,带钢表面质量明显改善。 For the problem of surface pockmarks of non-oriented silicon steel strip produced by a DMS Sendzimir mill, based on the production practice, the formation causes were analyzed from two aspects of emulsion and working roll.
