本发明涉及一种硅钢热处理方法，尤其涉及一种取向硅钢极薄带绝缘层涂覆方法，包括以下步骤：(1)接入普碳钢引带的准备工作；(2)各炉段张力的设定工作；(3)炉内气氛及温度的调节工作；(4)绝缘层厚度及厚度的检测工作；(5)极薄带涂层涂覆及烘干工作；(6)极薄带表面绝缘涂层及磁性能检测工作。本发明采用与极薄带厚度相当的普碳钢作为引带，通过引带测试产线张力和绝缘层涂覆的厚度，一方面可通过普碳钢薄带的运行加速炉内温度和气氛的稳定性，节约炉内稳定时间；另一方面可通过成本较低的普碳钢检测炉内张力和温度的设定，及绝缘涂层的涂覆效果，避免开始采用硅钢带出现断带，及涂覆不合格后造成产品报废带来的成本升高。

为提高无取向硅钢导磁性能,研究了不同剪切方式对无取向硅钢剪切处磁畴结构的影响。利用纳米磁流体观测无取向硅钢剪切后边部磁畴结构。结果表明,硅钢无论在机械剪切还是线切割后的边部磁畴都会发生不同程度的改变:线切割对边部磁畴结构改变较小,边部磁畴分布均匀且连续,在距边缘0～20μm范围内出现磁畴宽度变小现象;机械剪切对磁畴的改变较为严重,剪切处磁畴零乱且不连续,在距边缘20μm处仍难以观察到完整的磁畴结构。 The effects of different shearing modes on magnetic domain structure of cold rolled non-oriented silicon steel are studied in this paper.The magnetic domain of cold rolled non-oriented silicon steel is observed by nanometer magnetic fluid pattern method.The results show that the edge magnetic domain structure will be changed by mechanical shear and wire-electrode cutting,the variation of edge magnetic domain structure wire-electrode cutting edge is very small,the magnetic domain structure is wel...

采用取向分布函数分析了无取向电工钢不同再结晶退火温度下的织构变化及织构对磁感应强度和铁损的影响,并计算了无取向电工钢的磁晶各向异性能。结果表明,随着实验钢的再结晶退火温度升高,Goss织构和立方织构组分显著增强,而{111}面织构强度却减弱。较高的退火温度有利于减小织构因子,提高磁感应强度。磁晶各向异性能计算结果显示,随着再结晶退火温度升高,无取向电工钢板的磁晶各向异性能降低。 The recrystallization texture and the relationship of texture to magnetic induction intensity and core loss of a non-oriented electrical steel were investigated by orientation distribution function analysis.

对3层高硅电工钢复合板铸坯进行热轧及温轧变形加工后，采用正火、退火两种热处理方式处理，并观察轧制过程中产生的裂纹，研究不同状态下复合板的磁性能。对不同状态下的试样进行扩散退火处理，研究复合板中裂纹变化及其对磁性能的影响。结果表明：不同热处理工艺下合金内部的裂纹尺寸差异明显，裂纹尺寸对复合板的磁性能影响显著，相对于深裂纹，其他因素的影响较小；温轧变形加工后，复合板内层出现有序组织，但该有序组织在合金存在深裂纹的前提下并不能从本质上提高合金的磁性能；扩散退火工艺可以消除复合板内部的浅裂纹及微裂纹，但不能消除尺寸较大的裂纹，故而不能显著提高存在深裂纹的复合板的磁性能。 After hot rolling and warm rolling deformation processing of casting billet for three-layer high silicon electrical steel composite plate, it was normalized and annealed for heat treatment.
