摘要： The present invention provides a grain-oriented electrical steel sheet having magnetic properties equal to, or higher than, those of conventional steel sheets can be produced economically with high productivity, and a method for producing such a steel sheet. The producing method comprises the steps of using, as a starting material, a coil obtained by heating a slab having a composition comprising, in terms of percent by weight, 0.02 to 0.15% of C, 2.5 to 4.0% of Si, 0.02 to 0.20% of Mn, 0.015 to 0.065% of Sol. Al, 0.0030 to 0.0150% of N, 0.005 to 0.040% as the sum of at least one of S and Se and the balance substantially consisting of Fe and hot rolling the slab to a coil, or a coil directly cast from a molten steel having the same components as the slab, conducting hot rolled sheet annealing at 900 to 1,100.degree. C., one stage cold rolling the sheet by a tandem mill having a plurality of stands, conducting decarburization annealing, further conducting final finish annealing, and then applying final coating so that a product having a thickness of 0.20 to 0.55 mm, an average grain diameter size of 1.5 to 5.5 mm, a W.sub.17/50 value expressed by the formula given below and a B.sub.8 value satisfying the relation 1.80.ltoreq.B.sub.8 (T).ltoreq.1.88:0.5884e.sup.1.9154t .ltoreq.W17/50 (W/kg).ltoreq.0.7558e.sup.1.7378t [t: sheet thickness.]

摘要： A magnetic shield structure having openings, the structure comprising a plurality of similar magnetic blind bodies 2, each blind body 2 having an imaginary blind core plane F and a plurality of magnetic material slats 1 being spaced from each other by a distance d required for magnetic shielding, each slat 1 intersecting the blind core plane F at a longitudinal central axis C thereof, the longitudinal central axes of the slats are oriented substantially in parallel to each other on the blind core plane F. The blind bodies 2a, 2b are coupled in a row by serially coupling each slat 1 in each blind body 2a to a corresponding slat 1 of adjacent blind body 2b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2a, 2b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2a, 2b form openings in the magnetic shield structure. Preferably, three or more magnetic blind bodies 2 are coupled in a row so as to form a closed magnetic path. The blind bodies 2a, 2b may be stacked side by side in such a manner that the blind core plane Fa, Fb are parallel to each other and orientation of the slat central axes in each blind body 2a, 2b being selected so as to optimize attenuation of magnetic field across the magnetic shield structure.
