Title: Shin-ich Teraoka: Innovator in Stainless Steel Production

Introduction

Shin-ich Teraoka is a notable inventor based in Futtsu, Japan. He has made significant contributions to the field of materials science, particularly in the production of stainless steel. His innovative approach has led to advancements in the quality and workability of stainless steel products.

Latest Patents

Teraoka holds a patent for a process for producing a thin sheet of Cr-Ni-based stainless steel. This process involves continuously casting stainless steel represented by 18% Cr-8% Ni steel using a continuous casting machine. The method ensures rapid solidification at a cooling rate of 100°C/sec or more, resulting in a cast strip with a thickness of 10 mm or less. After solidification, the cast strip is cooled from a high temperature at a rate of 100°C/sec or more to 1250°C, preventing the occurrence of recuperation. The cooled cast strip is then held in a temperature range of over 900 to 1250°C for 5 seconds to 2 minutes before undergoing cooling, coiling, annealing, pickling, and cold rolling.

Career Highlights

Teraoka is associated with Nippon Steel Corporation, where he has applied his expertise in stainless steel production. His work has been instrumental in enhancing the surface quality and workability of stainless steel products, making them more suitable for various applications.
