■要約
The production process of base metals, such as steelmaking process, has an extremely important role in supporting the development of an eco-friendly human society and it becomes to an age of technical innovation toward an eco-friendly society. For the research and development of this field, we have to consider the following points on four different scales: 1) Giga scale: Consider the global impact of the extraction process of base metals from the earth's resources.2) Mega scale: Enhance the performance and efficiency of reactors to establish eco-friendly production processes.3) Micro scale: Identify the physical and chemical factors that control the reaction rate and material characteristics.4) Nano scale: Control the mass transfer rate of molecules among different phases to increase the reaction rate or produce ultrafine structures.At Kitamura laboratory, the following researches based on the above four points are being carried out in the field of steelmaking, which is a core process used to produce high-quality steel.
