摘要
采用大型刚塑性有限元软件建立立轧/平轧的三维热应力耦合轧制模型,并将其应用到宝钢2050粗轧机组仿真研究中。选取宝钢轧制带钢的现场实际参数进行模拟计算,得出的粗轧出口宽度值与实测值吻合良好,充分验证了模型的有效性。为了解决宝钢2050粗轧机组宽度难以控制的问题,本文对现场各种轧制工艺的宽展进行了仿真计算,并给出了自然宽展、纯狗骨宽展、综合宽展的分布规律。
A 3D thermo-mechanical coupled model for vertical/horizontal rolling is established using a rigid-plastic FEM software,and is applied to simulate the rolling processes of 2050mm roughing trains in Bao Steel.The calculated width of strip using the actual parameters is in good agrecment with the measured value at the exit of roughing,thus the model is effective.Aiming at the question that the strip width is control difficult to in this study,the spreading law is investigated by FEM simulation.The law of the strip spreading (natural spread,dogbone spread and combined spread) is obtained.
