Title: Heiji Morise: Innovator in Steel Pipe Cooling Technology

Introduction

Heiji Morise is a notable inventor based in Fukuma, Japan. He has made significant contributions to the field of materials engineering, particularly in the cooling methods of steel pipes. His innovative approach has implications for the manufacturing and durability of steel products.

Latest Patents

Morise holds a patent for a method of cooling steel pipes. This method involves holding quenched steel pipes at a tempering temperature for a specified duration before cooling them relatively rapidly. The cooling process includes spraying water onto the external surface of the pipes at a controlled flux, starting when the pipe temperature is between 400°C and 700°C. The cooling is concluded when the temperature reaches between room temperature and 350°C, achieving a mean cooling rate of 5°C to 40°C per second. This technique enhances the collapse strength of the pipes by inducing appropriate tensile residual stress on their internal surfaces while minimizing the cooling floor area.

Career Highlights

Heiji Morise is associated with Nippon Steel Corporation, a leading company in the steel industry. His work has been instrumental in advancing cooling technologies that improve the performance and reliability of steel products.
