Modern oxy-fuel burner/injectors in electric arc furnaces (EAFs) play a critical role in scrap melting, liquid steel refining, and slag foaming. However, varying operational modes, combined with dynamic process conditions, expose the injector panel surface to intense thermal conditions that can compromise efficiency and safety. In this study, four high-resolution Rayleigh backscattering-based fiber optic sensors were embedded in the oxy-fuel burner/injector panel of a DC EAF and continuously monitored temperature during two production days. The sensors identified localized hot spots, provided spatially resolved temperature distributions, and correlated thermal behavior with key process parameters such as furnace power, oxygen flow, and carbon injection. Elevated temperatures exceeding 176 °C were observed after the second scrap charge in six of the 47 heat cycles. The results revealed that inconsistent slag coverage on the injector panel's hot face was a primary factor in localized overheating. These findings demonstrate the potential for using distributed fiber optic sensing to enhance thermal management of oxy-fuel systems, optimize energy usage, and improve operational safety in modern EAF steelmaking.
