A bar is made using the hot rolling method. It is important to make the temperature distribution clear for the precise estimation of the material shape and the controlling texture. Thus, we analyzed the flow of the material in bar rolling by the energy method using finite element division. In this paper, we deal with the temperature distribution in bar rolling. The temperature distribution near the material-roll contact surface changes drastically. We propose the following new method for the analysis in the neighboring region of the contact surface. We apply the finite difference method to this region, and apply the finite element method to the other region. Consequently, the following results are obtained. (i) Temperature at the material-roll contact surface depends highly on the frictional condition and the circumferential velocity of the roll. (ii) Temperature becomes high at the central part of the material near the contact surface, in the square-diamond pass and round-oval pass; whereas in the square-oval pass, the temperature becomes high at the side part of the material near the contact surface.
