本发明涉及硅钢片叠片领域，具体涉及一种硅钢片自动叠片设备，包括滑移架、安装座和若干个单层碟片机，每个单层碟片机均包括码放架、横向拉移机构、下压机构、两个同步拉进机构、双层同步下压机构、传动连接器、第二弹性安装座、三个第一弹性安装座和五个电磁铁，通过双层同步下压机构，通过传动板能够与传动连接器之间自动分离，避免使用驱动源进行分离，降低了设备成本，通过传动连接器带动传动管进行移动，减少使用驱动源，降低设备的成本，传动连接器进行下降时也将带动传动管进行下降，使得中部硅钢片、两个纵向硅钢片和横向硅钢片之间进行同时下降，增加了工人的观察时间，减少出现硅钢片偏移的风险。

目前高磁感冷轧硅钢生产过程中，采用经验方法确定的乳化液流量设定值往往会造成硅钢产品的磁感性能达不到预期目标，针对此情况，基于轧机轧制机理研究了的乳化液流量数学模型，确定了乳化液流量设定值。实践表明，使用该数学模型输出的乳化液流量设定值，可提高轧制过程中乳化液流量控制精度，从而提高高磁感冷轧硅钢的轧制性能。 In view of the current production process of high magnetically inductive cold-rolled silicon steel, the mathematical model of emulsified fluid flow based on mill rolling mechanism is studied in view of the situation in which the magnetic sensing performance of silicon steel products is often not up to the expected target by using empirical method to determine the emulsified liquid flow setting. Practice shows that the emulsified fluid flow setting value output from this mathematical model improv...

本发明公开了一种用于测量电工钢片的二维磁性能的系统及方法，所述系统通过将承载待测样品的托盘与旋转机构连接，在测量各个角度的二维磁性能时只需控制旋转机构驱动待测样品转动，旋转机构的负载很小，旋转机构的制作较为简单。而且，励磁测量线圈是绕制在托盘的外围，而不是在磁轭上，这样使得待测样品相当于处于一个均匀的螺线管中，磁场更加均匀，保证了磁场测量的准确性，并且励磁源不需要像RSST一样要保证两路励磁机构的相位差的准确度，从而使得励磁源的制作更加简单，降低了制作的成本和门槛。同时，不需要对待测样品打孔来绕制线圈，待测样品无破坏，可以保证待测样品的完整性以及数据的重复性和可对比性，测量结果更可靠。
