METHOD OF MAKING SHEET OF TEXTURED ELECTRICAL STEEL Russian patent published in 2016 - IPC C21D8/12 C21D9/46 C22C38/60 H01F1/16 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. To reduce losses and deviations of values of losses in the electrical grain-oriented steel sheet manufacturing method involves hot rolling of slab from steel containing, wt%: C: 0.002-0.10, Si 2.0-8.0 and Mn 0.005-1.0 for producing hot-rolled sheet, if necessary annealing in hot zone conditions, single, double or multiple cold rolling of hot rolled steel sheet with intermediate annealing between them to produce final thickness sheet, decarburizing annealing of cold-rolled sheet in combination with primary recrystallization annealing, application of annealing separator on the surface of steel sheet and final annealing. Wherein during heating under decarburizing annealing fast heating is carried out at the rate of not less than 50 °C/s in the range of 200~700 °C with holding at the temperature of 250-600 °C for 1-10 s.

EFFECT: obtaining final thickness sheet.
