一种使铋收得率不低于70%的含铋取向硅钢冶炼方法,其步骤:常规转炉冶炼并出钢至钢包中;RH精炼处理,其间:控制渣层厚度不低于45mm,且渣成分在:Al2O3:25~35wt%,CaO:40~50wt%,MgO:10~15wt%,且结束时钢水温度控制在1530~1590℃;真空精炼结束后进行镇静;后将铋颗粒与石灰石颗粒混装容器加入钢水中;保护浇注和后工序生产。本发明将铋颗粒与石灰石颗粒混合加入,石灰石在钢液中分解产生的气体不仅可以减缓铋颗粒下沉速度,使铋能够快速扩散均匀,更主要的是还可以强化铋颗粒在钢液中的扩散,最终可获得铋收得率高于70%即在71~75%的理想效果。

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. The results show that the emulsion has a certain effect on the formation of surface pockmarks defects, but it is not the main factor. The main reason is that the working roll diameter of the 20-high Sendzimir mill is small, and the running period of the roll rolling the same l...
