Title: Hajime Komatsu: Innovator in Electrical Steel Technology
Introduction
Hajime Komatsu is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of electrical steel technology, holding a total of 4 patents. His innovative approaches have enhanced the performance and efficiency of electrical steel sheets, which are crucial in various electrical applications.
Latest Patents
One of his latest patents is a process for the preparation of oriented electrical steel sheets that have a high magnetic flux density. In this process, a primary recrystallization annealed steel sheet is nitrided for a short period at temperatures of 800 degrees Celsius or less, preventing substantial growth of crystal grains. The nitrided sheet is then held at a temperature range of 700 to 800 degrees Celsius for at least four hours during the temperature rise to the final annealing temperature. This allows the nitride formed during nitriding to dissolve and re-precipitate, transforming into a thermally stable nitride containing aluminum. Another notable patent involves a method for producing a grain-oriented electrical steel sheet using a novel (Al, Si)N inhibitor instead of conventional inhibitors. This innovative approach enhances the magnetic flux density by forming a fine inhibitor in large amounts.
