Далее подвергают закалке в морской воде, холодной прокатке пластины до толщиныA 2.3 mm thick hot rolled steel sheet containing 2.95% by weight of silicon, 0.025% by weight of soluble aluminum and 0.0058% by weight of total nitrogen is heated to LLP-IOOS, subjected to incomplete rolling with reduction from O to 26 % and incubated for 4 s. It is further subjected to quenching in seawater, cold rolling the plate to a thickness

After that, hot rolled steel sheets are cold rolled to a thickness of 0.30 mm, decarburized annealing in raw hydrogen at 830 ° C for 3 minutes and high-temperature annealing at 1200 ° C for 20 hours. In the table. 3 shows the magnetic characteristics of steel sheets, processed by the proposed method.
