Ahead of the transition to a carbon-neutral era, low-carbon steel process design and eco-friendly recycling of materials after use are expected to become key issues in the material industry in the future. To reduce carbon emissions, the use of hydrogen-reduced iron (H-DRI) and iron scrap will increase exponentially, and it is necessary to design a process for producing high-clean steel products using these materials as raw materials. In addition to the control of sulfur, phosphorus, and inclusions, which are impurities in existing steel products, the effect of tramp components such as copper and tin flowing in during scrap recycling after use and gangue components flowing in when H-DRI is used on the cleanliness of molten steel is expected to be a new research topic. is. In addition, the recovery of valuable metals from materials emitted after production and use (used secondary batteries, slag, dust, etc.) will be an important flow in future material process research.

In the Graduate School of Steel Energy Materials, the reaction between high-temperature melts (molten metals including steel, oxides, etc.) prediction and control, and conducting research to improve the added value of materials through clean metal production and recycling.
