| Abstract Scope |
Fiber optic sensors offer significant advancements for metalmaking process control, enhancing measurement accuracy and system integration in harsh environments. Our research focuses on the development and application of these sensors for real-time monitoring of temperature, strain, and chemical compositions. These sensors' small size, EMI immunity, and distributed sensing capability provide precise data, supporting Industry 4.0 initiatives. Key innovations include high-resolution thermal mapping via Rayleigh scattering-based OFDR, optical fiber interferometry for real-time mold gap measurement, distributed strain measurement, and an in situ Raman probe for analyzing molten slag and flux compositions. These technologies enable precise temperature profiling, strain monitoring, and chemical analysis, improving process control, product quality, and operational efficiency. Supported by industry leaders and government funding, our work aims to advance monitoring practices in the metalmaking industry. In this talk, current advancements and potential emerging applications of fiber optic sensing methods in metalmaking and casting will be reviewed and discussed. |
