| 摘 要： | 电工钢生产线上都具有在线铁损曲线数据，为现场产品质量的及时诊断提供了有价值的信息，但不少企业对该数据尚未充分利用，既未将其用于产品整卷质量定量评价，也未用于考察工艺参数对磁性影响的统计性分析和各种质量问题的自动诊断。本文结合对现场数据的一些了解，以及检测现场工艺参数调整时磁性能变化遇到的困难，提出利用这些数据定量整体评价整卷质量的思路，并初步编制了相关计算机软件，随着该系统在实践运用中的进一步完善，必将可以更好利用这些数据精确评价、控制整卷产品的质量。

| Abstract: | On-line determined core loss data are massively produced during production of electrical steels and these data provide timely much more and much valuable information for the evaluation and adjustment of product properties. However, the application of such data for property evaluation and control is still far from satisfactory in steel plants, namely neither are they used for the evaluation of whole coil of a steel strip and determination of the effects of parameter changes on the magnetic properties, nor for the further self diagnosis of different kinds of problems reflected in the on line core loss curves. This work collects some on line core loss curves and analyzes their features and possible existing problems or phenomena based on the difficulties encountered during searching the relationship between processing parameters and magnetic properties. Suggestions for evaluating the properties of whole coils of electrical steel strips quantitatively are given and a preliminary version of software is compiled hoping that this may get the attention from industry to best making use of on line core loss data for evaluating properties of whole coils of strips. |
