Abstract Roller leveling process of longitudinal profile (LP) plate is hardly studied because plate thickness changes. Deformation characteristics and residual curvature during LP plate leveling process were investigated based on curvature integral by elastic-plastic differences. It was found that entry intermesh section is reduced with increasing thickness and entry intermesh should be from 0��7 to 1��1 mm for LP plate with 42/54 mm in thickness. In order to get satisfactory flatness along longitudinal direction, small entry intermesh should be selected and exit intermesh should be 0 mm. In addition, thickness section for LP plate which can be leveled by 11 roller leveler is from 24 to 60 mm. Finally, there is an intermesh schedule that could level LP plate with initial curvature less than elastic limit curvature.
