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.
