Title: The Innovative Contributions of Hitoshi Ohsugi

Introduction

Hitoshi Ohsugi, an esteemed inventor based in Chiba, Japan, has made significant contributions to the field of steel manufacturing. With a total of two patents to his name, he has demonstrated expertise in developing processes that enhance the quality and efficiency of molten steel production.

Latest Patents

Ohsugi’s latest patents focus on advancing the techniques used in the treatment of stainless molten steel. One of his notable inventions is a method of degassing and decarburizing stainless molten steel in a vacuum. This innovative process involves foaming the molten steel within a vacuum tank, which increases the nitrogen content before foaming begins. The foam is produced through the denitrification of the steel during the vacuum degassing process, whereby oxidizing gas is introduced to facilitate the decarbonization of the steel. This reaction not only removes carbon but also helps to maintain the temperature of the molten steel through the combustion of carbon monoxide produced during the reaction.

Another important patent pertains to the process for fusing steel slabs in the longitudinal direction. This technique involves fusing the steel slab while maintaining a temperature of over 500°C and a speed exceeding 300 mm/min. To ensure quality, the surface portion of the slab, including the lower part of the fused surface, is mechanically removed through cutting or grinding, ensuring a high standard of durability and performance in the final product.
