摘　　要：采用三维弹塑性有限元法模拟了不同立辊锥角的H型钢万能轧制过程,分析了立辊锥角大小对翼缘宽展和轧制力的影响。以工业纯铅为材料,采用在试件断面划分网格的方法,在燕山大学H型钢三机架连轧机组上进行了实验研究,验证了数值模拟结果的正确性。H-beam rolling processes with different vertical roll cone angles have been simulated by using three-dimensional finite element method. The effect of vertical roll cone angle on the flange spread and rolling load are analyzed. To validate the comput- ational results, H-beam rolling experiments were carried out by using lead specimens at the Three-stand Universal H-Beam Mill in Yanshan University. The deformation characteristics of specimens in rolling were observed clearly by a method of dividing H-beam sections into elements. The measured values is in agreement well with the calculated results.
