本发明涉及取向硅钢技术领域，且公开了一种气耗优化成本较低的取向硅钢高温退火工艺，包括如下步骤：S1、将铸坯装炉装炉前先对炉台利用高压空气进行清扫，将通气管内的粉尘或其它杂质吹扫干净，然后根据钢卷的卷径大小选用与之匹配的料盘和料筐，将铸坯放入炉内；S2、炉台密封将装有铸坯的炉台完全密封。该种气耗优化成本较低的取向硅钢高温退火工艺，在高保温阶段使用氨分解气，而氨分解气相对氢气而言比较稳定，在生产成本上也较氢气低，大大的降低了成本节约了能耗，在低保温阶段是为了消除应力，形成一次再结晶晶粒，进行脱碳，高保温阶段二次再结晶，净化钢质和形成烧结硅酸镁底层，最后退火完成后，完成烧结绝缘涂层、热拉伸平整。

结合工业化生产过程中出现的同卷带钢头、尾磁性能差异现象,对50SW1300牌号无取向硅钢同卷带钢头、尾试样的夹杂物、晶体织构和显微组织进行了分析研究。结果表明,夹杂物、晶体织构是影响成品钢卷磁性能的重要因素。夹杂物是造成同卷带钢头、尾铁损差异的主要原因。夹杂物数量越多,尤其是小尺寸的夹杂物数量越多,对成品带钢的磁性能影响越大,对于本试验而言,AlN和MnS是影响成品带钢磁性能的主要夹杂物。晶体织构是造成同卷带钢头、尾磁感应强度差异的主要原因。有益的{100}和Goss织构含量越大,有害的{111}<110>和{111}<112>织构含量越小,即有益织构与有害织构含量比越大,成品带钢的磁感应强度越大。 Based on the industrial manufacture of non-oriented silicon steel sheets 50SW1300, the magnetic property variation of head and tail of the same finished steel sheets was discussed by analyzing non-metallic inclusion, crystal texture, and microstructure.

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.
