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. Results show that, both of the non-metallic inclusion and the crystal texture will affect the magnetic properties significantly. The non-metallic inclusion is the key factor of the core loss variation of head and tail of the same finished steel sheets. The more the non-metallic inclusion, especially the small non-metallic inclu-sion, the greater the inclusion impacts on the finished steel sheets. For present work, AlN and MnS are the main inclusions which will main affect the magnetic properties. Moreover, the crystal texture is the key factor of the magnetic induction variation of head and tail of the same finished steel sheets. The more the helpful {100} and Goss texture, and the less the harmful {111}<110>and {111}<112> texture, the better is the magnetic induction of the finished steel sheets.
