Abstract The straightening curvature as the main straightening parameter in the design of the roller shape of two-roller straightener， decides the quality of straightening. So as to improve straightening precision， the mechanism of two-roller straightener was analysed deeply based on the elastic-plastic theory， which was developed considering the strengthening of material for the bar. After choosing the curvature based on theory of straightening， the shape of straightening roller suiting for φ100～φ150mm bars was designed by increasing the transition section. Then the finite element model of two-roller straightener was established based on the finite element software—Marc， straightening quality was analysed about the working process of two-roller straightener after the simulation， providing theoretical basis for the actual production.
