【Abstract】 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.更多还原
