Abstract (en)
[origin: EP0588342A1] Very high magnetic flux density grain-oriented electrical steel sheet containing 2.5 to 4.0 weight percent silicon as an essential component and having a very high magnetic flux density B8 of not less than 1.92 tesla, in which by area not less than 80 percent is accounted for by matrix secondary recrystallization grains having a diameter not larger than 100 mm and not smaller than 10 mm in a direction of cold rolling and not larger than 50 mm and not smaller than 5 mm in a direction perpendicular to the cold rolling direction, and in which, moreover, of the grains in said matrix, not fewer than 50 percent are fine secondary recrystallization grains having an average diameter not larger than 5 mm. <IMAGE>
