快速铸轧条件下轧制压力的建模与仿真

通过建立轧制压力模型，对常规铸轧进行了仿真计算，计算结果与实测数据相符合，从而验证了模型的合理性，在此基础上，对快速铸轧进行了虚拟仿真研究，研究结果表明：不增强铸轧辊内、外冷却能力，单纯减薄铸轧板坯即可提高铸轧速度；随着铸轧速度降低与铸轧区增大以及铸轧坯厚度减薄，轧制压力峰值增大；随着铸轧辊径增大，轧制压力提高，因此铸轧机力能设计参数也要相应增大。

Model and Simulation of Draught Pressure Distribution under the condition of High-speed Roll Casting

The static equilibrium differential equation in casting and rolling zones during high-speed roll casting process is deduced respectively using the slab method. The equation in the casting zone is numerically solved by Runge-Kutta method and that in the rolling zone is analytically solved according to the mixed fric- tional condition. Conventional roll casting of a roll caster is simulated based on these established models. The validity of these models is verified by the agreements of the calculating results with the experimental. Based on this fact, the virtual simulation of high-speed roll casting is carried out. Comparis on with the conventional roll casting of a roll caster shows that the designed parameters of mechanical properties of the roll caster under the condition of high-speed roll casting should be raised.
