This paper introduces the numerical simulations of the blade rolling technology by MSC/superform of American MARC Co.,in which two kinds of finite element models-symmetrical model and asymmetrical model are set up.By analyzing the impact on neutral angle friction coefficient between the billets and roll under two kinds of models,it is found that the neutral angle increases with the friction coefficient and the deformation zone metal increases in the forward slip zone.On the contrary,if the friction coefficient is too small it will affect the normal billet grip,appearing the skidding phenomenon.The simulation result shows that the friction coefficient of 0.3 is the best.The deformation zone metal flow conditions are different in the different troughs under different simulation models.The workpiece formed by the asymmetric trough appears the bending phenomenon because of the different flow rates at the upper and lower surface metal.The workpiece formed by the symmetrical trough is relatively straight.So,it is better to choose the symmetrical trough form.This paper provides the references for establishing the blade rolling technology by optimizing the design parameters.
