Abstract

The bottom anode in the direct current electric arc furnace (dc EAF) is critical for completing the electrical circuit necessary for sustaining the arc within the furnace. For pin-type bottom anodes, monitoring of the temperature of select pins instrumented with thermocouples (TCs) is performed to track bottom wear in EAF and inform the operator when the furnace should be removed from service. This work presents the results from a plant trial using distributed temperature monitoring of bottom anode pins in a 165-ton dc EAF over a two-month service period utilizing two optical fiber sensing techniques: fiber Bragg grating (FBG) and Rayleigh backscattering (RBS). The early detection of temperature anomalies along the length of the anode pin through distributed sensing enhances operational safety, providing a robust alternative to traditional TCs.

利用分布式光纤传感器推进直流电弧炉底阳极温度监测

直流电弧炉（dc EAF）的底部阳极对于完成维持炉内电弧所需的电路至关重要。对于针脚式底部阳极，使用热电偶（tc）对选定针脚的温度进行监测，以跟踪电炉底部的磨损情况，并通知操作员何时应将炉从使用中移除。本工作介绍了一项工厂试验的结果，该试验利用两种光纤传感技术：光纤布拉格光栅（FBG）和瑞利后向散射（RBS），在165吨直流电弧炉中对底部阳极引脚进行了为期两个月的分布式温度监测。通过分布式传感对阳极引脚长度的温度异常进行早期检测，提高了操作安全性，为传统tc提供了一种强大的替代方案。
