Abstract The basic mathematical model of curvature analysis was built for the plate during leveling process. The model was solved with the numerical algorithm successfully with quick speed and well convergence. The research results can be shown as follow: the difference of the contact angles between the plate and the several front rollers is larger than that of the rest, this difference diminished gradually with the movement of the plate, but there is a little influence on trajectory for different initial curvatures; the plate with different initial curvatures tends to be flat with the action of the same rolling reduction; the imposed and residual stresses distributions represent polygon lines, the residual stress can be controlled in a small range after leveling.
