Effect of Cold Rolling Process Parameters on the Thickness Deviation of SUS301L Stainless Steel Plate
To investigate the effect of cold rolling process parameters on
the thickness deviation of SUS301L stainless steel plate, a quarter-symmetry model of a 20-high cold rolling mill was established using ABAQUS finite element software. The control variable method was employed to analyze the effects of front tension, back tension, and rolling speed on the thickness uniformity of the steel plate. The standard deviation of the thickness deviation was used to quantify the thickness fluctuation. The results show that as the front tension increases from 130 MPa to 160 MPa, the standard deviation decreases from 6.46×10⁻
3
to 6.19×10⁻
3
; when the front tension is further raised to 190 MPa, the standard deviation increases to 7.22×10⁻
3
. A minimum standard deviation of 5.75×10⁻
3
is obtained at a back tension of 85 MPa, and the flatness deteriorates when the back tension exceeds 115 MPa. The thickness distribution is most uniform when the rolling speed is in the range of 6-7 m/s, with a standard deviation of 5.75×10⁻
3
at 6 m/s. When the speed increases to 8 m/s, the standard deviation rises to 8.06×10⁻

. Comprehensive analysis indicates that the optimal combination of process parameters for achieving the most uniform thickness distribution of the SUS301L stainless steel plate is a front tension of 160 MPa, a back tension of 85 MPa, and a rolling speed of 6-7 m/s. This study provides a theoretical basis for improving thickness uniformity and reducing waviness and other shape defects in actual production.
