Presentation Title: Wettability study between liquid slags and refractories during a splash process of the converter.

Professor Yongsug Chung earned his Bachelor’s degree in Metallurgical Engineering from Yonsei University in 1990, followed by his M.S. and Ph.D. degrees in Materials Science and Engineering from Carnegie Mellon University in 1995 and 1999, respectively. Upon completion of his doctoral studies, he served as a research professor at the University of Toronto in Canada for two years. He subsequently worked for seven years as a manager of new steel product development at Dongbu Steel (now KG Steel) in Korea.

Since 2009, Professor Chung has been a faculty member at TU Korea, where he has held the positions of assistant professor, associate professor, and currently, full professor. He also served as the Dean of Students from 2021 to 2022. In addition, he was a visiting professor at the Institute of Multidisciplinary Research for Advanced Materials (IMRAM), Tohoku University, Japan, in 2017.

Professor Chung’s research interests focus on high-temperature interfacial phenomena involving molten steel and slag, molten steel and refractory materials, and slag and refractory materials. His work includes investigating the corrosion and erosion of refractory materials such as MgO-C and Al₂O₃, as well as the removal of non-metallic inclusions during the steelmaking process. He has actively contributed to solving critical issues in refractory materials and steelmaking slags within the Korean steel industry. He is the author of approximately 100 patents and academic publications, with over 1,200 citations. Based on his contribution, he was awarded the Hyundai Steel Academic Award in 2025 from KIM+.  He has been the Korean chairman of the Korea-China Joint Symposium on Steel Science and Technology since 2021
