Title: The Innovations of Inventor Nagayasu Bessho

Introduction

Nagayasu Bessho, an accomplished inventor based in Chiba, Japan, has made significant contributions to the field of continuous metal casting. With a prolific portfolio of 18 patents, his innovative techniques stand out as valuable advancements in metallurgy and manufacturing processes.

Latest Patents

Among his latest patents is a breakthrough method and apparatus for continuous casting of metals. This unique process involves applying a non-moving, vibrating magnetic field to molten metal within a casting mold. The innovative approach imposes vibration solely on the molten metal, which results in cast slabs that are much less susceptible to flux entrainment, bubble capture, and non-metal inclusions near the metal surface.

The magnetic field is generated by strategically arranging electromagnets on both sides of the mold, ensuring they lie parallel in the direction of the mold’s longitudinal width. Supplying a single-phase AC current to each coil with a frequency ranging from 0.10 to 60 Hz enhances the casting process. Furthermore, Bessho’s technique allows for the intermittent application of a static magnetic field, significantly reducing defects such as flux entrainment and surface segregation in the cast slabs.

Career Highlights

Bessho's career is marked by his tenure at leading companies, including Kawasaki Steel Corporation and Hitachi, Ltd. His involvement in these organizations has undoubtedly played a role in shaping his innovative ideas and techniques.
