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.

本发明公开了一种取向硅钢高温退火底板，涉及钢卷生产技术领域，解决了钢卷的尺寸变形导致钢卷切边量过大的技术问题。包括应变诱导板，应变诱导板的板面开设有若干凹槽，相邻凹槽之间于应变诱导板的板面形成凸楞，钢卷放置于应变诱导板的板面上，其中部分的钢卷端面支撑于凸楞上，其余的钢卷端面悬置于凹槽上。本发明通过在应变诱导板上设置凹槽与凸楞，钢卷在高温退火过程中同样受重力产生蠕变变形，但蠕变变形按照凸楞所设定的方向进行，从而将产生的不均匀的“大浪”分割成碎化均匀的“细浪”，使得钢卷边部的变形细小、均匀、可控，从而降低了大象脚变形的缺陷影响程度，减小了钢卷的切边量，提高了成材率，同时能够获得良好的边部板形。
