Title: The Innovations of Takahiro Kan
Introduction
Takahiro Kan is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of electromagnetic steel production, holding a total of 13 patents. His work focuses on improving the properties of steel used in various applications, particularly in enhancing magnetic flux density and surface appearance.
Latest Patents
One of his latest patents is a method of producing a non-oriented electromagnetic steel strip. This method involves subjecting a low-carbon steel slab to hot-rolling, cold rolling at a small reduction, and first annealing. Specific conditions are employed to coarsen the crystalline structure, which helps achieve a controlled and moderate crystal grain size after annealing. The slab is cold-rolled at a reduction of about 5 to 15% and subjected to first annealing by heating at a rate of about 3°C/sec or higher, holding the strip for about 5 to 30 seconds at 850°C to the A3 transformation temperature of the steel. This process controls the crystal grain size to about 100 to 200 micrometers after first annealing.
Another notable patent is for producing grain-oriented silicon steel sheets that have less iron. In this innovation, grain-oriented silicon steel sheets containing MnSe as a main inhibitor are designed to reduce iron loss. This is achieved by increasing the magnetic flux density and realizing the thinning of product thickness while fine dividing the crystal grains. In this case, 0.02-0.30% of copper is added to the slab of the grain-oriented silicon steel, and specific conditions are applied during decarburization annealing and/or final finish annealing.
