In order to study the effect of tension on profile shape of single pass rolling strip of 304 austenite stainless steel (/% : 0. 053C

based on explicit dynamic finite element method

the simulation and analysis on cold rolling process of 2 mm steel strip with four high mill have been carried out by ANSYS/LS-DYNA software. Results show that with reduction 0. 06 mm

forward tension 13 ~ 40 MPa and backward tension 1 ~ 18 MPa rolling process

the edge of rolled strip is acted under compressive stress and the middle part is acted under tensile stress led to produce tiny edge wave； with increasing forward tension from 15 MPa to 21 MPa； the strain of strip along width direction trends towards uniform

i. e. increasing forward tension is available to improve the flatness of strip

and increasing backward tension is also available to improve the profile shape of strip and its effect is more obvious that increasing forward tension.
