鉄鋼に代表されるベースメタル製造プロセスは、人類社会の発展を支える基盤素材として、ゆるぎない立場にあるが、環境調和社会に向けて新たな技術変革の時を迎えています。この分野を見る時には、以下の4つの視点(スケール)を俯瞰しなければなりません、(1)地球から得た資源を使い、地球に優しいプロセスで抽出する[Giga Scale]、(2)反応装置(リアクター)の効率・性能を極限まで高める [Mega Scale]、(3)反応速度、材料特性を支配する物理的化学的要因の解明 [MicroScale]、(4)元素の異相間移動速度の測定、微細組織制御技術[NanoScale]本研究分野では、鉄鋼製造プロセスにおいて高機能鉄鋼材料を作り込むコアとなる「製鋼」を対象に、資源戦略に基づく環境調和型プロセスの探索、プロセスシミュレーションモデルの開発、高温化学反応の速度論的研究、高機能鉄鋼材料を支える高純度化技術の開発等に関して、前記の4つの視点に立脚した研究を行っています。

The production processes of base metals, such as steelmaking process, play an extremely important role in supporting the development of an eco-friendly human society. For the research and development in this field, we must consider the following points on four different scales. First is the giga-scale, which relates to the global impact of base metals extraction from the earth. Second is the mega-scale, which describes enhancing the performance and efficiency of reactors to establish eco-friendly production processes. Third is the micro-scale, whereby we must identify the physical  and chemical factors that control reaction rates and material characteristics. Fourth is the nano-scale, for which controlling the mass transfer rate of molecules among different phases can be used to increase the reaction rates or produce ultrafine structures. In Kitamura laboratory, the following research based on the four points mentioned above are being carried out in the field of steelmaking, which is a core process for producing high-quality steel.

❖Development of an eco-friendly process using a byproduct of the process

❖Development of a process simulation model

❖Kinetic studies of chemical reactions in steelmaking

❖Direct observation of micro-scale phenomena at high temperatures
