Definitions

  • the present invention based on the above findings provides that the average grain size of ferrite is 50 ⁇ m or more, and the compressive residual stresses ⁇ S and ⁇ C in the width direction at the steel plate surface and at the center of the thickness measured by the X-ray stress measurement method are It is a non-oriented electrical steel sheet characterized by being 2.0 MPa or more, respectively.
  • the 2 ⁇ -sin 2 ⁇ method using the ⁇ -Fe (211) peak is used as the X-ray stress measurement method.
  • the above non-oriented electrical steel sheet of the present invention is characterized by containing at least one group of ingredients from Groups E to I below in addition to the above ingredient composition.
  • Group E Ti: 0 to 0.005 mass%, Nb: 0 to 0.005 mass%, V: 0 to 0.010 mass% and Ta: at least one of 0 to 0.002 mass% Group F; B: 0 to 0.002 mass% and Ga: at least one of 0 to 0.005% Group G; Pb: 0 to 0.002 mass% ⁇ H group; Zn: 0 to 0.005 mass% Group I; at least one of Mo: 0 to 0.05 mass% and W: 0 to 0.05 mass%
  • B 0 to 0.002 mass% and Ga: at least one of 0 to 0.005 mass%
  • B and Ga are harmful components that form fine nitrides and increase iron loss. If the value is exceeded, the adverse effects become noticeable. Therefore, B and Ga are preferably added in the ranges of B: 0 to 0.002 mass% and Ga: 0 to 0.005 mass%, respectively. In addition, more preferable upper limit values are B: 0.001 mass% and Ga: 0.002 mass%.
  • a test piece having a width of 30 mm and a length of 280 mm was taken from the finish-annealed sheet thus obtained, and the iron loss W 1/5k was measured by the Epstein test. The value of the eddy current loss We1/5k at 0.1 T and 5 kHz was calculated by the method. Also, the iron loss W 15/50 at 1.5 T and 50 Hz was measured using the above test piece. Further, the residual stresses ⁇ S and ⁇ C in the sheet width direction of the finish-annealed sheets were measured by the method described above.
  • the slab was heated to a temperature of 1150° C. for 30 minutes and then hot rolled to obtain a hot-rolled sheet having a thickness of 1.8 mm.
  • the hot-rolled sheet was subjected to hot-rolled sheet annealing at 950° C. for 10 seconds, pickled, and cold-rolled to obtain a cold-rolled sheet having a final thickness (product thickness) of 0.20 mm.
  • the cold-rolled sheet is soaked in a continuous annealing furnace with a maximum temperature of 1020 ° C.
