摘要： A grain-oriented electrical steel sheet with improved magnetic properties is achieved by a reduced 180° C. magnetic wall spacing with pulse laser light irradiation. The rolling direction width of the periodic closure domain generated by laser irradiation is no greater than 150 &mgr;m. The depth of the periodic closure domain in the direction of the steel sheet thickness is at least 30 &mgr;m. The product of the length of the periodic closure domain in the rolling direction width direction multiplied by the length of the depth of the periodic closure domain in the direction of the steel sheet thickness is at least 4500 &mgr;m2. The magnetostriction with materials of 0.23 mm sheet thickness (&lgr;19 p-p compression) is no greater than 0.9×10−6, and magnetostriction with materials of 0.27 mm sheet thickness (&lgr;19 p-p compression) is no greater than 1.3×10−6.

摘要： A box annealed steel strip having small strains is produced by: pretreating a steel strip in such a manner that a side edge portion thereof is thermally treated under a different condition from another condition under which the remaining portion, including an opposite side edge, thereof is thermally treated, so as to cause the longitudinal length of the side edge portion to be different from that of the remaining portion; winding the pretreated steel strip under tension to form a coil in such a manner that greater tensile stresses are produced in the other one of the side edge portion and the remaining portion, which one has a longitudinal length smaller than that of the other one, than those produced in the other one; placing the coil on a base plate so that a side edge included in the portion having the greater stresses comes into contact with the base plate, and; box annealing the coil on the base plate in a box annealing furnace.
