His innovative methods have advanced the manufacturing processes of steel, particularly in enhancing magnetic properties.

Latest Patents

Manabe's latest patents include a method of producing non-oriented electromagnetic steel strips. This method involves subjecting a low-carbon steel slab to hot-rolling and cold rolling at a small reduction, followed by first annealing. The process aims to improve the magnetic flux density and surface appearance of the product. Specific conditions are employed to coarsen the crystalline structure, achieving 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. The strip is held for about 5 to 30 seconds at 850°C to the A3 transformation temperature of the steel, while controlling the crystal grain size to about 100 to 200 micrometers after first annealing.
