摘要： A heat-resistant magnetic domain refined grain-oriented silicon steel, a single-sided surface or a double-sided surface of which has several parallel grooves which are formed in a grooving manner, each groove extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel, and the several parallel grooves are uniformly distributed along the rolling direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. Each groove which extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel is formed by splicing several sub-grooves which extend in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. The manufacturing method for a heat-resistant magnetic domain refined grain-oriented silicon steel comprises the step of: forming grooves on a single-sided surface or a double-sided surface of a heat-resistant magnetic domain refined grain-oriented silicon steel in a laser grooving manner, a laser beam of the laser grooving is divided into several sub-beams by a beam splitter, and the several sub-beams form the several sub-grooves which are spliced into the same groove.

摘要： When a Si content (mass%) is set to [Si], an Al content (mass%) is set to [Al], and a Mn content (mass%) is set to [Mn], a parameter Q represented by "Q = [Si] + 2[Al] - [Mn]" is 2.00 or more, the total mass of S contained in sulfides or oxysulfides of Mg, Ca, Sr, Ba, Ce, La, Nd, Pr, Zn, or Cd is 10% or more of the total mass of S contained in a non-oriented electrical steel sheet, a {100} crystal orientation intensity is 3.0 or more, a thickness is 0.15 mm to 0.30 mm, and an average crystal grain diameter is 65 µ m to 100 µ m.
