Abstract: FIELD: method of production of electrical-sheet steel with oriented structure with final strip thickness ranging within 0.1 to 0.5 mm from flat blanks with regulated composition of alloy. SUBSTANCE: invention is distinguished by the fact that flat blanks alongside with manganese and copper have high content of sulfur and low content of aluminum. Flat blanks before hot rolling are heated to reduced temperature and held at this temperature for required time. This temperature is below the temperature of diffusion of manganese sulfides and higher than the temperature of diffusion of copper sulfides. Then flat blanks, if needed, are subjected to hot roughing and then with reduced final rolling temperature, preferably within the range of 900 to 970 C, rolled after annealing of hot strip preferably in the range of 950-1100 C. One-stage or two-stage cold rolling up to final thickness of strip, definite recrystallization annealing with simultaneous decarburization, application of separating means, high-temperature annealing and finish annealing with application of insulating coating are resulted in obtaining electrical-sheet steels with oriented grain structure. Produced strips (Tissen grain orientation TGO) have the same magnetic induction as in the known steels (normal grain orientation RGO and highly permeable grain orientation HGO) but improved hysteresis losses.
