摘要： A grain oriented electrical steel sheet has sufficiently low iron loss and having less conventionally-concerned warpage of the steel sheet even after the steel sheet is subjected to artificial magnetic domain refining treatment, where strain-introducing treatment is conducted with high energy so that an iron loss-reducing effect can be maximized. The grain oriented electrical steel sheet is obtained by adjusting tension to be applied to a tension-applying insulating coating, or to both surfaces of the steel sheet by the tension-applying insulating coating, before strain-introducing treatment in the range of Formula (1): 1.0≦(tension applied to non-strain-introduced surface)/(tension applied to strain-introduced surface)≦2.0 (1), and by controlling the amount of warpage of the steel sheet toward the strain-introduced surface side after strain-introducing treatment in the range of 1 mm or more and 10 mm or less.

The process involves by full- or semi-processing, hot rolling a steel slab containing not more than about 0.03% by weight of C, not more than about 3% by weight of Si and not more than about 2% by weight of Al such that the equation [Si wt %]+3 [Al wt %]-6 [C wt %] is in the range of about 0 to 2; and cold rolling the hot rolled steel strip in a known manner, followed optionally by finish annealing and also optionally by skin-pass rolling. The coil is finish rolled at a peripheral roll speed between about 500 to 1,500 mpm at the final stand. The peripheral roll speed at the final finish rolling stand is also controlled within a range of no more than about 300 mpm. Hot rolling is completed at a temperature Tf (.degree.
