Presentation title: Decarbonizing ironmaking process and technologies at Hyundai Steel

Yong-hee Kim obtained Ph.D in Department of Metallurgical Engineering at Seoul National University in 2000, and has been working at Hyundai Steel Co. and conducting research in various fields.

Research has been conducted on various metallurgical phenomena in the iron and steelmaking process, such as a study on the dross behavior in a molten zinc pot and solidification in a continuous casting mold based on numerical analysis, a study on the metallurgical behavior and inclusions effect from steelmaking to continuous casting molds, and a study on the effect of iron ore in the ironmaking process and the operation of high-efficiency blast furnaces.

As the demand for the decarbonized steel process grows, research is continuing to produce high-quality automobile steel sheet while reducing carbon emissions in the iron and steelmaking process.
