PRODUCTION OF GRAIN-ORIENTED MAGNETIC STEEL SHEET HAVING LOW IRON LOSS

PURPOSE:To stably produce the subject grain-oriented magnetic steel sheet having a low iron loss at a low cost by locally removing a glass film on a grain-oriented magnetic steel sheet, applying the powder of V, Mo, Cr, Ti, and Nb, annealing, and then cooling the sheet in a specified magnetic field....

Zusammenfassung:	PURPOSE:To stably produce the subject grain-oriented magnetic steel sheet having a low iron loss at a low cost by locally removing a glass film on a grain-oriented magnetic steel sheet, applying the powder of V, Mo, Cr, Ti, and Nb, annealing, and then cooling the sheet in a specified magnetic field. CONSTITUTION:The glass film or the glass film and insulating film on the grain-oriented magnetic steel sheet which has been finish-annealed or finish- annealed and then coated with the insulating film are locally removed to expose the ground iron in the plane of the steel sheet. The magnetic steel sheet contg.
