The severe plastic deformation (SPD) procedure designated continuous confined strip shearing (CCSS/C2S2) technique based on rolling, equal channel angular pressing (ECAP) and Conform principle was simulated numerically by using finite element code DEFORM-3D. The influences of rolling reduction ratio on restoration ratio of work-piece geometry, effective strain, output velocity of processed work-piece, torque of rollers, and energy consumption feature for the C2S2 procedure were investigated. The results show that rolling reduction ratio has significant influences on C2S2 procedure. With the increase of rolling reduction ratios (5%, 10% and 20%), the restoration ratio of work-pieces geometry reduced, the magnitude of effective strain kept almost unchanged, the output velocity of processed work-piece increased, the total torque of rollers decreased, and the energy consumption used for making unit volume work-piece subjected to unit straining reduced considerably. It was found that the optimal rolling reduction ratio was about ~10 %, where the energy consumption reduced by 8.16 %, whereas the restoration ratio of work-piece geometry was almost the same as constrasting with the rolling reduction ratio of 5 %.
