Method of producing a non-oriented electrical steel sheet

A method of producing a non-oriented electrical steel sheet, the method comprising:

• hot rolling a slab having a chemical composition consisting of, in mass %,
• C:
• 0.0050% or less,
• Si:
• 2.0% or more and 6.0% or less,
• Mn:
• 1.0% or more and 3.0% or less,
• P:
• 0.20% or less,
• S:
• 0.0050% or less,
• N:
• 0.0050% or less,
• Al:
• 0.0050% or less, and
• one or more selected from the group consisting of B:
• 0.0001% or more and 0.0050% or less, Nb:
• 0.0001% or more and 0.0050% or less, and V:
• 0.0005% or more and 0.0500% or less, with a balance consisting of Fe and inevitable impurities to obtain a hot-rolled sheet;
• coiling the hot-rolled sheet;
• subjecting the hot-rolled sheet to hot-rolled sheet annealing;
• thereafter cold rolling the hot-rolled sheet once or twice with intermediate annealing being performed therebetween, to obtain a cold-rolled sheet;
• and
• subjecting the cold-rolled sheet to final annealing,
• wherein the hot-rolled sheet after the hot rolling is cooled at an average cooling rate from 800° C. to 650° C. of 30° C./s or more, and thereafter the coiling is performed at 650° C. or less, and
• the hot-rolled sheet after the hot-rolled sheet annealing is cooled at an average cooling rate from 800° C. to 650° C. of 30° C./s or more.
