硅钢片磁参数快速测量的宽度效应处理

Handling of Width Effect of Silicon Steel Sheets during Rapid Measurement of Magnetic Parameters

着重讨论硅钢片磁参数快速测量中严重影响测量结果的试样宽度效应．提出用平均磁化场来处理宽度效应．分别测试了热轧硅钢片与冷轧硅钢片的磁化曲线，并与方圈法测试曲线进行了比较，两种方法测试数据误差小于8％．

Serious effect of sample width on rapid parameter measurement of silicon-steel sheets is discussed. In order to deal with the sample width effect. a concept of average magnetizing field is proposed. Magnetization curves of both cold-rolled and hot-rolled silicon steel sheets are measured respectively and compared with the curves measured with frame method. The relative error of test data obtalned by two methods is less that 8%.
