| Synopsis: The integrated manufacture of electrical steels in Mizushima Works since 1995 has bestowed upon electrical steel research much development, because the research department has been obliged to rightly reply to many difficult questions as to conditions in operating several new process lines. Especially, the efforts to the progress of electrical steel research have been made on quantative estimation for adequate values of materials such as components, precipitates, crystal structures, textures, surface microstructures, and so on. Moreover, the efforts have been made on constructing new theory of secondary recrystallization. Additionally, a research on magnetism has progressed in the field of magnetic domain refining techniques and in the area of applications of electrical steels for model transformers or model motors. These progresses have greatly contributed to the improvement of electrical steels and the development of new products at Kawasaki Steel. |
