Latest Patents

Muro 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, followed by cold rolling at a small reduction and 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 reach the A3 transformation temperature of the steel, while controlling the crystal grain size to about 100 to 200 µm after first annealing. Muro's innovative approach has led to advancements in the quality and performance of electromagnetic steel.
