| 摘 要： | 钢材含碳量在线无损检测技术在钢铁工业精确过程控制中起着至关重要的作用。电磁方法广泛应用于离线钢材含碳量的无损检测,但多数传统方法只是利用了电磁特性对含碳量敏感的特点,而忽视了电磁特性对温度敏感的特点。最近,利用电磁计算技术的多物理场软测量方法克服了这一缺点,取得了良好的效果。本文介绍采用涡流法、Barkhausen噪声法、宏观磁性能法和感应加热法4种钢铁材料中含碳量电磁无损检测方法的基本原理,阐述它们的研究现状及发展方向。通过比较分析各种测量方法的原理,分析了应用这些方法进行在线检测的可能性。

| Abstract: | Online nondestructive evaluation of carbon content of steel plays a key role for precise process control in iron and steel industry.Electromagnetic method has been widely utilized for offline nondestructive evaluation of carbon content in steel.However,most of these methods are based on the theory that electromagnetic property is sensitive to carbon content,and it is neglected that electromagnetic property is also sensitive to temperature.Recently,multiphysical field soft measuring method based on electroma... |
