FIELD: metallurgy.SUBSTANCE: electric sheet steel comprises flute formed from geometrical location of laser beam scanning points from one end edge to opposite edge of the sheet over sheet width, and crystalline grain interface line. Said line extends along said flute to penetrate the silicon steel sheet from front surface to rear surface. Note here that glass coat is made in said flute with Ir X-ray radiation intensity factor of magnesium at flute section is set to 0?Ir?0.9. Note here that mean X-ray radiation characteristic intensity of magnesium of textured electric steel other than flute section is set to 1.EFFECT: lower magnetic losses.2 cl, 8 dwg, 3 ex, 1 tbl |
