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... 

运用电子背散射衍射(EBSD)技术,研究了50W600无取向硅钢在热轧→冷轧→退火工序间织构的演变。结果表明:由于热轧板沿板厚方向的应力场和温度场存在差异,导致热轧板不同层织构类型和强度存在差异;热轧板表层主要存在铜型、黄铜和高斯织构,1/4层织构主要为α纤维织构和较弱的高斯织构,中心层织构较单一,主要为α纤维织构;和热轧板相比,冷轧板各层织构差异较小,为典型的轧制织构(α纤维织构和γ纤维织构);退火板各层都表现为γ纤维织构增强、α纤维织构减弱,旋转立方织构基本消失。 The texture evolution of 50W600non-oriented silicon steel in hot rolling,cold rolling and annealing process was investigated by electron back-scatter diffraction(EBSD)technology.Results show that the hot rolled plate texture types and intensities along thickness direction were different because of the different stress fields and temperature fields.The major texture types in the surface of hot rolled plate were copper,brass and Gauss texture.The texture was composed ofαfibre texture and weaker Ga...

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。
