摘要： A finish annealed non-oriented electromagnetic steel sheet includes about 0.01 wt % or less of C, greater than about 1.0 wt % and at most about 3.5 wt % of Si, at least about 0.6 wt % and at most about 3.0 wt % of Al, at least about 0.1 wt % and at most about 2.0 wt % of Mn, at least about 2 ppm and at most about 80 ppm of one or more rare earth metals (REM), a maximum content of Ti and Zr being about 15 ppm and 80 ppm, respectively, wherein oxygen on the surface layer of the steel sheet is 1.0 g/e2 or less. Since the non-oriented electromagnetic steel sheet has desirable mechanical properties resulting from the increased amounts of Si and Al, a high magnetic flux density can be maintained without sacrificing a punching property as well as very low iron loss can be obtained even after stress relief annealing.

摘要： A method and a low iron loss grain-oriented electromagnetic steel sheet are disclosed. The method comprises the steps of: hot-rolling a grain-oriented electromagnetic steel sheet; cold-rolling the hot-rolled steel sheet once or twice intervened by intermediate annealing, so as to achieve the sheet thickness of a final product; annealing the cold-rolled steel sheet for decarburization; finish-annealing the decarburized steel sheet; forming linear grooves on the steel sheet substantially perpendicularly to the rolling direction, after the final cold-rolling step and before the finish-annealing step, by, for example, electrolytic etching or acid dipping; and filling the linear grooves with an element selected from the group consisting of Sn, B and Sb, or an oxide or a sulfate of an element selected therefrom. Preferably, each of the linear grooves has a width of 30-300 &mgr;m and a depth of 5-100 &mgr;m, and extends at 60-90° to the rolling direction, and is apart from the adjacent groove by 1 mm measured parallel to the rolling direction.
