无孔型轧制模拟仿真研究与工程应用
|
摘要
采用DEFORM有限元分析手段,建立无孔型轧制全连轧仿真模型,通过设置合理的边界条件,模拟轧制过程,并结合样板厂生产实际数据对轧件各道次尺寸进行分析比对,求证了曲线拟合宽展公式的合理性,并通过对轧制力、温度等的分析得出无孔型轧制过程的变化规律。通过在样板厂B生产实践中的应用,验证了无孔型轧制数值模拟仿真技术的先进性。
DEFORM finite element analysis method is adopted to establish whole rolling of grooveless rolling, the rationality of the first width formula of curve fitting can be verified through setting the reasonable boundary conditions, simulating the rolling process,and combining with the actual data from demonstration plant, and comparing with each rolling pass dimension of rolling piece; and the varying pattern of grooveless rolling process can be got through the analysis of rolling force, temperature and so on. The advancement of numerical analog simulation technology for grooveless rolling is verified through application of the production practice of demonstration plant.
