Latest Patents

Kazumi Morita holds a patent for 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. The process aims to improve the magnetic flux density and surface appearance of the product by employing specific conditions to coarsen the crystalline structure. This results in 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. The crystal grain size is controlled to be about 100 to 200 micrometers after the first annealing.
