Abstract: According to the configuration of energy curves, an mathematical model of energy consumption in hot rolling mills has been built up. This model is a spline model. Then computer simulation has been performed by using the actually measured data of four steel plates 16Mn, 20G, 3C and A3 rolled by a reversing mill. As a result of the simulation, γ (the configuration index of energy curves) is determined, and mathematical demonstration and experimental verification of the spline model are conducted in comparsion with three other models-Imaiichiro model, power function model and parabola model which have drown much attention in recent years. The results show that the theoretical curve of the spline model is able to suit configuration of different experimental energy curves, whereas the other three models can only be fit for those experimental energy curves without an inflection point. In addition, the accuracy of the spline model is much higher than that of the others when fitting the data of the four steel plates is effected.
