Tetsuro Ohashi

Title: Tetsuro Ohashi and His Contribution to Electrical Steel Production.

Introduction

Tetsuro Ohashi is an inventor associated with Himeji, Japan, and Nippon Steel Corporation. His patent work addresses a process for producing non-directional electrical steel sheets designed to reduce ridging.

Latest Patents

The supplied information lists one patent for Ohashi: “Process for Producing Non-Directional Electrical Steel Sheets Free from Ridging.” The invention improves steel-sheet production by electromagnetically stirring unsolidified molten steel during continuous casting. The stirring takes place in a specified region of the slab, encouraging at least half of its central zone to develop an equiaxed structure. The process also specifies the steel composition and hot-rolling conditions, followed by single-step cold rolling and decarburization annealing. The stated aim is to produce non-directional electrical steel sheets free from ridging. Ohashi is credited with 1 patent in the information provided.

Career Highlights

Ohashi’s listed invention focuses on controlling slab structure during casting and subsequent rolling. This approach connects continuous-casting conditions with the quality of the finished electrical steel sheet. The supplied information identifies Nippon Steel Corporation as his company.

Collaborations

Hiromu Fujii and Masafumi Okamoto are listed as Ohashi’s coworkers. The provided details do not specify their roles in the patent or the invention.

Conclusion

Tetsuro Ohashi’s listed patent describes a steelmaking process that uses electromagnetic stirring to help prevent ridging in non-directional electrical steel sheets.
