Abstract: As reasonable interval between guides during two-roll straightening process was not easy to determine, a 3D elastic-plastic finite element model of the straightening process of bar material was proposed. Based on this model, variations of straightening force, supporting force of guides, degree of plastic deformation, residual stress and the maximum deflection of the bar after straightening were analyzed in different intervals. Reasonable range of interval between guides was determined by comprehensive consideration. The obtained range of interval by this study is larger than previously used range, and the frequency of change of guides is decreased.

Key words: metallic materials, rolling, two-roll straightening, interval between guides
