Abstract：

It is difficult to get a proper practical answer of bending deflection for H-Beam roller straightening.In this paper,based on adequate mechanics model and finite difference calculus,a practical method to solve bending deflection is put forward.Compared with the engineering method,it is shown that this kind of method is more reasonable,precise and useful.
