Abstract

Temperature monitoring is crucial in steelmaking for increased productivity, operational efficiency, and safety. Rayleigh Optical Frequency Domain Reflectometry (OFDR) technology using optical fiber provides a solution for obtaining spatially distributed measurements of temperature and strain, facilitating precise monitoring of vital parameters for safe operations. Conventional measurement methods, such as thermocouples, fall short of delivering distributed high spatial resolution measurements, particularly in remote locations requiring temperature monitoring. This work presents the integration of fiber optic OFDR sensors into steelmaking structures, showcasing their ability to detect even minor variations in temperature and strain with high sensitivity. This capability enables the early detection of issues such as overheating, water leaks, and abnormal structural stresses, ensuring proactive interventions.
