The 0.5 mm non-orientation silicon steel 50W470 (≤0.005C
1.45~1.65Si
0.2~0.4Al)coil was rolled by twenty- high Sendzimir mill from 2.0~2.8 mm plate with pass reduction 15%~35% and total reduction 75%~80%.The test results showed that with 5 pass rolling the grains in steel were all fibration
the tensile strength increased to 885~905 MPa from 480~560 MPa rolling billet
clongation s decreased to 0.79%~0.8% from 25%~28%.And the X-ray diffraction spectrum analysis showed that with 5 pass rolling the residual stress(secondary stress)existed in non-orientation silicon steel 50W470 which was main cause to form elliptical type stamping.
