Introduction

Seizo Mineyuki is an inventor associated with Himeji, Japan, and Nippon Steel Corporation. His patent work addresses a challenge in producing slightly deoxidized steel through continuous casting.

Latest Patents

The supplied information identifies 1 patent for Mineyuki: “Process for Continuous Casting of a Slightly Deoxidized Steel Slab.” The invention describes a method for suppressing bubble nuclei that can develop into carbon monoxide bubbles and cause defects during solidification.

The process combines molten steel with a free oxygen concentration of 50 to 200 parts per million, a mold with concave short sides, and opposing flows along the mold’s long sides. It also applies electromagnetic flow at the solidification interface, at a speed of 0.1 to 1.0 meters per second, while the steel solidifies. The stated aim is to produce a sound solidification layer without blowholes.

Career Highlights

Mineyuki’s patent focuses on extending continuous casting beyond killed steel to slightly deoxidized steel, including semikilled and rimmed steel. The described approach seeks to control rimming action in the oscillating mold and improve the quality of the cast strand.

Collaborations

The supplied information names Eiichi Takeuchi and Tetsro Ohashi as Mineyuki’s coworkers. It does not specify their roles in the patent or the invention.

Conclusion

Seizo Mineyuki’s documented patent presents a coordinated approach to controlling bubble formation and solidification in continuous casting, reflecting an effort to improve the production of slightly deoxidized steel slabs.
