Method for producing non-oriented electrical steel sheet

A method for producing a non-oriented electrical steel sheet comprising a series of steps of:

• subjecting a raw steel material having a component composition comprising C:
• not more than 0.005 mass %, Si:
• 1.0 to 5.0 mass %, Mn:
• 0.04 to 3.0 mass %, sol. Al:
• not more than 0.005 mass %, P:
• not more than 0.2 mass %, S:
• not more than 0.005 mass %, N:
• not more than 0.005 mass % and the remainder being Fe and inevitable impurities to a hot rolling to form a hot-rolled sheet,
• subjecting the hot-rolled sheet to a hot-band annealing and then to a single cold rolling or two or more cold rollings including an intermediate annealing between each cold rolling to form a cold-rolled sheet having a final sheet thickness, and subjecting the cold-rolled sheet to a finish annealing,
• wherein
• at least one pass in a final cold rolling of the cold rolling is a rolling conducted at a friction coefficient μ of not less than 0.030 and a rolling reduction of not less than 15%, where the final cold rolling refers to, when the final sheet thickness is achieved by a single cold rolling, the single cold rolling, or when the final sheet thickness is achieved by two or more cold rollings including an intermediate annealing between each rolling, a last cold rolling conducted after a last intermediate annealing.
