| 摘 要： | 通过25 kg真空感应炉熔炼,锻造开坯,1050～850℃热轧至1 mm,650℃温轧至0.3 mm,再冷轧成0.05 mm高硅钢(％:0.02C、6.56Si、0.14Mn、0.013P、0.004S、0.02Al)薄板。冷轧板经过1 200℃1.5 h真空退火后,得到无取向硅钢。与普通取向硅钢相比,在0.07 T,20 kHz的高硅钢薄板铁损降低14.7％,30 kHz的铁损降低19.7％,40 kHz的铁损降低28.1％;该钢是一种优良的软磁材料,在冷轧后的强度达1 480 MPa。

| Abstract: | The manufacture process of sheet of high silicon steel 0.02C,6.56Si,0. 14Mn,0.013P,0.004S, 0.02Al was melting by 25 kg vacuum induction furnace, forging breakdown,hot rolling to 1mm at 1050～850 ℃,warm rolling to 0.3 mm at 650℃,and cold rolling to 0.05 mm.The non-oriented silicon steel was got by vacuum annealing of the cold rolled sheet at 1200 ℃ for1.5 h. Compared with conventional oriented silicon steel,the iron loss of high silicon steel sheet decreased by 14.7% with0.07 Tand 20 kHz, by 19.7% with 30 kHzand by 28. 1% with 40 kHz,it is an excellent soft magnetic material. The tensile strength of the steel sheet cold rolled was up to 1480 MPa. |
