The AIST Howe Memorial Lecture Award was established in 1923 to honor the late professor Henry Marion Howe, who helped turn steelmaking from an art into a science. This award shall be selected every other year on the odd year. The honorary lecturer shall present a lecture on a technical subject of particular interest to the association.

"Fiber Optic Sensing Technologies Supporting Advancements in Steel Production and the Shift to Industry 4.0"

The manufacture of steel encompasses processes that operate under extreme environmental conditions that makes measurement of temperature, strain, position, and chemistry both difficult and expensive to implement. Yet, as Industry 4.0 methodologies are adopted in the manufacture of steel, it is imperative that new sensing systems be developed and adapted to enable the 4.0 technologies such as artificial intelligence, big data analytics, neural net learning and digital twins, and to confirm the accuracy of predictions made using these tools. Sensors based on optical fiber offer some unique advantages for the steelmaking environment, such as small size, electromagnetic interference immunity, distributed sensing capability and compatibility with the harsh environment. In this lecture, current advancements and potential applications of fiber optic sensing methods in steelmaking and casting will be reviewed and discussed.
