By analyzing the deformation of roll stack and condition of the stress, the online calculation mathematic model for roll gap with load is established using finite difference method based on Timoshenko's deep beam theory and the equilibrium differential equations of deformation. The model includes rolls flexing deformation and elasticity flatting. The complicating calculation of the conventional influence function method and the finite element method are avoided by using this mathematic model, and then the efficient of calculation is increased. By online using and the statistical analysis for the using result, it is improved that the mathematic model can meet the request of production for calculation accuracy and efficient. © All right reserved.
