The straightening is a process of the final step of the steel bar and the wire rod. This paper describes, more popular straightening process, 2roll-straightening technique, and its experimental results. Geometrical and static analysis of concave and a convex roll were done by using three dimensions FEM. The result was that the change in 2-roll angles were equal to amount of bend under straightening process. We produced the straightening experiment machine from the result. And the optimum angle between the roll and roll pressure for 2-roll straightening process was clarified in this paper.
