一、绪言在无取向硅钢的铁损中,磁滞损失占65—75%。因为晶粒直径越大磁滞损失越小,所以在生产高级产品时,努力使晶粒直径长大。无取向性硅钢板生产是将普通热轧板经冷轧后进行短时间退火。在退火时作为阻止正常晶粒长大主要是细小分散的析出物。本报道就是报道研究添加稀土类元素来防止发生细小弥散的析出物的效果。

I. INTRODUCTION In iron loss of non-oriented silicon steel, hysteresis loss accounts for 65-75%. As the larger the grain diameter, the smaller the hysteresis loss, so in the production of advanced products, efforts to make the grain diameter grow. Non-oriented silicon steel production is the ordinary hot-rolled plate after cold rolling for a short time annealing. In annealing as a precipitate to prevent the growth of the normal grain is mainly finely dispersed. This report is about the effect of adding rare earth elements to prevent the formation of finely dispersed precipitates.
