The continuous casting process is a critical step in steel manufacturing, where real-time monitoring is essential to ensure product quality and process efficiency. However, the extreme temperatures and harsh environmental conditions pose significant challenges for conventional sensing technologies. This project focuses on the design and development of high-temperature Electromagnetic Acoustic Transducer (EMAT) sensors, tailored for monitoring the continuous casting process of steel. By leveraging the principles of non-contact ultrasonic wave generation and detection, the proposed EMAT sensors are engineered to operate reliably in elevated temperature environments. The research emphasizes sensor material selection, optimization of transduction efficiency, and thermal resilience to address the unique challenges posed by steel casting. Successful implementation of these sensors will enable enhanced process control, defect detection, and improved operational safety, paving the way for advancements in high-temperature industrial sensing applications.
