摘要
Abstract
A three-dimensional thermomechanical coupled finite element model was developed using Abaqus to address temperature non-uniformity and optimize process parameters synergistically in the roughing stage of a no-reheating direct rolling line for bars.The model enables a dynamic,strong-coupled simulation of the rolling force,temperature,and deformation fields.By employing adaptive mesh refinement,it quantitatively characterizes the fluctuations in rolling torque,the core-to-surface temperature gradient,and the velocity field distribution.This model provides a theoretical foundation for process optimization,effectively suppressing the end-temperature gradient induced by the direct rolling process and minimizing head-to-tail property variation within the same batch of products.关键词
