The objective of the research was the development of a fiber-coupled, optical pyrometer for continuous temperature measurement in a vacuum degasser that reduces process time, enhances process control, and eliminates manual or robot-operated thermocouples. Through the live testing performed at US Steel's Edgar Thompson Works, the challenges associated with making optical temperature measurements in a vacuum chamber were identified. As a result of these challenges it was determined that continuous temperature monitoring in RH-type degassers was not a viable alternative to standard immersion thermocouples. The project was not successful
