摘要

使用非接触式电磁传感器对电站钢的电磁性能进行分析是有意义的，因为这些性能表明了材料的微观结构。在本文中，我们提出了圆柱形电站钢样品(即P91和P9等级)在不同条件下的测量。首先测量了这些钢样品的B-H曲线。然后采用印刷电路板线圈集成传感器测量增量磁导率。采用解析和数值方法(有限元法)计算了这些样品的传感器响应。得到了一系列样品的实验结果，并通过有限元模型与测量结果拟合推断了样品的电磁特性。

Non-contact EM measurement of the properties of power station steels taken from service

Analysis of the electromagnetic properties of power station steels, measured using a non-contact EM sensor, is of significance as such properties are indicative of the microstructure of the material. In this paper, we present the measurement of cylindrical power station steel samples (namely P91 and P9 grades) in different conditions. Initially the B-H curves of these steel samples were measured. Then printed circuit board (PCB) coil integrated sensors were used to measure the incremental permeability. Analytical and numerical methods (Finite Elements Methods) were employed to calculate the sensor response of these samples. Experimental results were obtained for a range of samples and their electromagnetic properties inferred by fitting finite element models to the measured results.
