Japanese Patent JP2021025128
Kind Code:
A
Abstract:
To provide a grain oriented electrical steel sheet having a linear groove formed on the surface of the steel sheet and excellent in threading performance.SOLUTION: The grain oriented electrical steel sheet is provided in which a groove is formed in the surface thereof, the groove extending in a direction intersecting a rolling direction and having a depth in a direction being a sheet thickness direction, the grain oriented electrical steel sheet has fine structures in the ranges of at least 10 mm from both ends in the width direction to the width center direction of the steel sheet. The fine structure in the range of at least 10 mm to the width center direction from both ends has an average grain size of 5 mm or less, and the existence frequency of a crystal grain having 10° or less of a deviation angle from a Goss orientation is 50% or less.SELECTED DRAWING: Figure 3
