Abstract: The effect of bending radius(2.5~7.5 mm),tension load(20～80 N)and rolling direction of specimen on reversed bending times of imported cold rolled non-orientation silicon steel sheet has been tested. Results showed that as bending radius R was 5 mm,with increasing tension load from 20 N to 60 N,the reversed bending times of longitudinal specimen decreased from 24 to11,and with increasing tension load from 60 N to 80 N,the reversed bending times was constant; and as tension load was 60 N,with increasing bending radius R from2.5 mm to 7.5 mm,the average reversed bending times of longitudinal specimen increased from 6.5 to20.7.The reversed bending times of longitudinal specimen was higher than that of transverse specimen by 6.6%~22.7%.
