About Lab.

The Clean Steel Laboratory analyzes the characteristics of various physicochemical reactions that occur at high temperatures and conducts research to apply them to the improvement of the steel production process and recycling of resources after use. Core steel processes such as refining reaction to control molten iron components and improve cleanliness of molten steel, removal and control of inclusions, and optimization of steelmaking and continuous casting processes are the main research subjects. In order to prepare for the low-carbon process, which is emerging as a key topic not only in steel but also in all industries, we are also making efforts to research the application of scrap and direct reduced iron to the steel process, which is important for reducing carbon emissions in the steel sector. In order to understand the mechanism, reaction rate, and final reaction equilibrium of various reactions that can occur at high temperatures, theoretical studies are being conducted on high-temperature computational thermodynamics, high-temperature melt properties, and reaction rate analysis, and various high-temperature experimental techniques are applied to support this. are doing In order to overcome the limitations of the existing high-temperature reaction-based metal refining process, we are making new attempts such as our laboratory's unique droplet utilization reaction and electricity application reaction.

In addition, in order to preserve and develop the expertise of our laboratory at the point of transition to a future eco-friendly society and high-temperature metal processing, we are conducting research on the recycling of scrap iron and secondary battery scrap, which are spent resources, and research on hydrogen energy production. . We apply the principle of high-temperature physicochemical reaction to all research conducted in the laboratory, and are pioneering new research fields based on the acquired knowledge.

Students who want to take on the challenge of solving problems and phenomena that occur in high-temperature metal processing, please pay attention to our laboratory. You will gain professionalism and pride as a metallurgist by conducting research that applies various high-temperature experimental techniques and thermodynamics and kinetics to reality.
