研究了无取向硅钢钙处理前后夹杂物的行为,重点考察了钙处理前后夹杂物的成分、类型、形貌和尺寸研究的变化情况,为实际生产中无取向硅钢的钙处理提供理论指导。试验发现:钙处理前夹杂物主要以Al2O3、Al2O3-MgO为主,且在夹杂物表面有AlN析出,钙处理后夹杂物以Al2O3-MgO-CaS-CaO系复合夹杂物为主,还含有少量的SiO2或AlN;钙处理前后,夹杂物形貌由多边形或不规则形逐渐向球形或近似球形转变,并且夹杂物尺寸不断增大;钙处理前后,含钙夹杂物的比例发生突变,由10%增大到74.5%,且随着钙处理时间的延长,含钙夹杂物比例下降,表明钙处理使夹杂物变性后易聚集长大并上浮去除。 Behavior of inclusions before and after calcium treatment in non-oriented silicon steel was researched by investigating changes of compositions,types,shapes and sizes of inclusions before and after calcium treatment,for the purpose of providing theoretical guidance for calcium treatment of non-oriented silicon steel in actual situation.

本发明涉及涂层液技术领域，且公开了取向硅钢绝缘涂层液，其配比为：二氧化硅10‑15%、硼酸5‑8%、磷酸二氢盐2‑5%、金属溶胶20‑25%、氢氧化铝占5‑6%、有机酸处理的复合盐溶液20‑30%、分散剂0.5‑1%，其余为水，采用硅溶胶作为辅助成膜物，粘结力较强，对附着性影响很大。硅溶胶能够很均匀地包裹在被胶结物质的表面，通过自干成膜，保持了很高的常温结合强度；而磷酸盐涂层的固化是通过受热分解，脱水聚合完成的，低温强度差，中温强度高，充分利用了硅溶胶低温的结合强度和磷酸盐中、高温时的结合性能，消除了常规涂层烘烤时容易出现的收缩、起泡现象，阻止了微气孔的形成，提高了涂层的表面光滑度，粘结强度和稳定性同时保持绝缘涂层的光泽、光滑和稳定性。

对低温法生产的以AlN为主抑制剂的Hi-B取向硅钢高温退火过程进行了中断实验,借助EBSD及TEM技术对高温退火连续升温过程中织构与析出物的演变进行了研究。实验结果表明,800℃时ODF图出现高斯织构组分,但强度很弱,高斯晶粒偏离角在10°以上;950~1 000℃时高斯晶粒异常长大,偏离角3~6°;高温退火过程析出物主要有球形、规则立方形及不规则多面体形3种形貌,由于渗N的影响,Zener因子先增大再减小,并且析出物在高斯晶界前沿优先粗化。 The annealing process at high temperature of Hi-B silicon steel using low slab reheat temperature and with AlN as the inhibitor has been studied by interrupting test,and the evolution of texture and precipitates during continuous heating-up in the annealing process at high temperature was analyzed by EBSD and TEM.

利用电子背散射衍射(EBSD)技术和场发射电子扫描显微镜(FESEM)研究了电工钢中柱状晶不同初始取向50%热压缩变形后的演变规律及其对粒子析出行为的影响。结果表明:〈100〉晶粒形变后仍为〈100〉取向,只发生绕ND∥〈100〉方向的转动,具有遗传性,粒子析出数量少。柱状晶长轴与压缩轴的偏转度增加,取向的稳定性变差,超过40°,可形成〈111〉取向,期间发生复杂的滑移系交互作用,产生较高的缺陷密度,促进粒子析出。MnS粒子主要在晶内析出,变形温度高、形变量低,粒子均无法充分析出。回复时,形变晶粒内高的储能和缺陷密度是促进粒子进一步析出的必要条件。 The evolution of initial orientations and their influence on precipitation of columnar-grained electrical steel after 50% hot compression deformation were investigated by electron backscatter diffraction technique and field emission scanning electron microscopy.The results indicate that the〈100〉orientated columnar grains remain still〈100〉after hot compression deformation,with only rotation around ND parallel to〈100〉direction,with heredity,and less precipitation.As the deviation angle between the...
