Title: Yohichi Zaizen: Innovator in Electrical Steel Manufacturing
Introduction
Yohichi Zaizen is a prominent inventor based in Tokyo, Japan. He is known for his significant contributions to the field of electrical steel manufacturing. With a focus on innovative methods, Zaizen has developed a unique approach that enhances the properties of electrical steel sheets.
Latest Patents
Zaizen holds a patent for a manufacturing method of grain-oriented electrical steel sheets. The process involves heating a slab with a predetermined composition at temperatures ranging from 1280°C to 1390°C. This step allows for the solid-solution of a substance functioning as an inhibitor. Following this, the slab is hot-rolled to obtain a steel strip. The steel strip undergoes annealing to form a primary inhibitor, followed by one or more cold-rolling processes. Further annealing is performed to achieve decarburization and primary recrystallization. Finally, nitriding treatment is applied in a mixed gas of hydrogen, nitrogen, and ammonia, leading to the formation of a secondary inhibitor. The steel strip is then annealed again to induce secondary recrystallization.
Career Highlights
Zaizen's career is marked by his dedication to advancing manufacturing techniques in the steel industry. His innovative methods have not only improved the quality of electrical steel sheets but have also contributed to the efficiency of production processes.
