本文介绍了一种新型多频传感器系统在工业棒磨机上的应用。该系统通过分析杆对包含一定频率范围的激励信号的响应来操作。传感器系统能够成功地监测材料的转化。传感器配置，可以部署在线已被认为是一个原型系统已建成并在斯坎索普棒轧机安装在增强冷却区的斯泰尔莫部分进行测试。初步结果显示，表明相位谱基本上是不受升离和铺设模式的运行表上的棒的变化。该系统还能够检测不同等级钢的不同相谱，并检测已知会影响微观结构的工艺特征。
This paper describes the application of a new multifrequency sensor system to an industrial rod mill. The system operates by analysing the response of the rod to an excitation signal which contains a range of frequencies. The sensor system is able to successfully monitor the transformation of the material. Sensor configurations that could be deployed online have been considered and a prototype system has been built and tested in the Stelmor section of the Scunthorpe Rod Mill fitted in the enhanced cooling zone. Initial results are shown, demonstrating that the phase spectra is essentially unaffected by variations in lift-off and the lay pattern of the rod on the run-out table. The system was also able to detect different phase spectra from different grades of steel and also to detect features of the process which are known to affect microstructure.
