Abstract:
1. A method for producing a non-oriented magnetic steel sheet comprising: annealing a hot-rolled steel sheet containing, by mass %, C: 0.005% or less; Si: 2% to 4%; Mn: 1% or less; and Al: 3% or less, with the balance being Fe and inevitable impurities, so as to obtain an annealed hot-rolled steel sheet; cold-rolling the annealed hot-rolled steel sheet so as to obtain a cold-rolled steel sheet; plating a surface of the cold-rolled steel sheet with V so as to obtain a plated cold-rolled steel sheet; and subsequently annealing the plated cold-rolled steel sheet at a temperature between 900°C and 1000°C for one hour or more.
