Abstract (en)
Provided is a method of manufacturing a grain-oriented electrical steel strip having excellent magnetic properties, that is, high magnetic flux density in particular, which is characterized in that the average diameter d of grain (primary recrystallization grain) of a material before final annealing is set to a value greater than 15 mu m and the coefficient sigma * of deviation in grain diameter is set to a value less than 0.6. According to the present invention, the aggregation to the {110}<001> orientation of a product can be made to be remarkably high so as to obtain a product having a high magnetic flux density B8 which is equal to or greater than 1.88 tesla.
