MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617096464 A) filed by Jfe Steel Corporation on August 10, 2026, for Grain-Oriented Electromagnetic Steel Strip, Laminated Iron Core, And Method For Producing Grain- Oriented Electromagnetic Steel Strip.
Inventors include Omura Takeshi; Ichihara Yoshihisa; and Nakamura Koji.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention reduces BF. This grain-oriented electromagnetic steel strip includes magnetic domains subdivided by strain introduced linearly so as to intersect the rolling direction on at least one surface. The ratio of the region in which the maximum distance between magnetic walls of a reflux magnetic domain measured by an X-ray magnetic circularly polarized light-emitting microscope in the inner part of the strip thickness is 10 µm or more to the total length in the rolling direction of the grain-oriented electromagnetic steel strip is 50% or more.
