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。

研究了硅钢铸坯再加热过程中夹杂物的析出行为。采用非水溶液电解提取+扫描电镜观察方法,观察了试样的显微组织,统计了夹杂物的尺寸、种类、数量、分布。结果表明,均热温度为1 523 K时,水淬试样的夹杂物尺寸绝大部分小于0.5μm,0.5~5.0μm的夹杂物数量很少,没有发现5.0μm以上的夹杂物。此外,均热时间为10、30、60、90、120、240 min时,对应试样中0.05~0.2μm的夹杂物数量分别为4.04×104、4.73×104、3.70×104、3.33×104、3.10×104、1.56×104个/mm3。绝大部分夹杂物以MnS、AlN、CuxS类为主,并以三类夹杂物中的两类复合或三类复合居多。三类复合夹杂物总量占每组试样夹杂物总量的90%或以上。随均热时间延长,典型的夹杂物组成会发生如下变化:MnS+AlN+CuxS MnS+AlN AlN。与此同时,MnS、AlN、CuxS三者复合比例从45.2%(均热10 min)降为9.7%(均热240 min)。 The methods of electrolysis extraction from nonaqueous solution and scanning electron microscope were adopted to study the precipitation behavior of non-metallic inclusions in Si steel slabs during reheating processes.The morphologies,chemical compositions,quantity and size distribution of non-metallic inclusions in these steel samples were analyzed.Results show that,when the soaking temperature is 1 523 K,almost all of the non-metallic inclusions are smaller than 0.5 μm,few are in the range of ...
