利用EBSD技术研究了电工钢中长轴平行于轧向的柱状晶样品在热轧和退火过程中组织和取向的演变规律,并与长轴平行于板法向的样品的已有研究结果进行对比。结果表明,无论柱状晶按何种方向排列,只要表面存在剪切力,热轧后都可形成剪切织构,同时中心形成轧制织构,主要包括旋转立方织构和{112}<1-10>。柱状晶造成的影响主要体现在板中心层,长轴平行于轧向排列的样品热轧时形成的粗大旋转立方晶粒要到脱碳退火后才能完全消除,但破坏了正常的不同取向晶粒间的取向差分布及尺寸均匀性,导致二次再结晶不完全及磁性能降低。 The evolution of microstructure and grain orientation in an electrical steel containing columnar grains with its long axis being parallel to the rolling direction of sheet was studied during hot rolling and annealing by EBSD technique.The results are compared with those of samples containing columnar grains being parallel to normal direction of sheet reported in the reference [3].It was shown that,whether the long axis of columnar grains was arranged in RD or ND,shear textures can be formed in t... 

本实用新型公开了用于变压器铁芯硅钢片的叠片翻转支架，包括槽板，所述槽板内部卡装有转板，转板两侧对称安装有卡杆，槽板底部安装有风扇；所述转板另外两侧对称安装有放置槽，放置槽底部卡装有电磁铁，转板两侧皆设置有两组开关；在开关不受到压力时，此时开关所在电路处于通电状态，开关与电磁铁为电性连接，每个开关独立控制一组电磁铁，电磁铁处于工作状态，电磁铁正常运行产生的磁吸力，使得铁芯硅钢片固定在放置槽内，在使用机械臂取用铁芯硅钢片时，机械臂底部连接的触发条持续压迫开关，此时开关所在电路处于断路状态，开关所控制的相应电磁铁不产生磁力，机械臂可以较为容易的取用铁芯硅钢片。
