In bar rolling, a bar is usually made by applying front and back tension, so it is important to analyze the effect of the front and back tension on rolling properties. Further more, it is also important for precise rolling to confirm the ratio of the variation in rolling properties to the change of tensions. In this paper, the analysis of the effect of tension was performed by the energy method using finite element division, which we have proposed previously. First, the effect of the front and back tension on spread, forward slip, roll force and roll torque were proved reasonable by comparison with the experimental formula. Next, the ratio of the variation of the roll torque to the change in tension was obtained approximately using the results of no tension applied. As the roll radius increases, the ratio of the variation of spread, forward slip, roll force and roll torque to the change in tension decreased. As the reduction and height / width ratio of caliber increases, the ratio of the variation of roll torque to the change in tension decreased.
