摘　　要：采用有限元方法将轧制过程轧件的应力应变与温度状态进行耦合计算 ,使有限元对斜轧过程的模拟更加准确。为轧辊和顶头磨损分析提供了依据。经轧辊与顶头实测结果分析 ,说明计算结果是可靠的。轧件在入口和出口的计算与实测温度平均值符合较好。This paper employed the quasi-coupled rigid-plastic FEM with thermal FEM for calculating the strain, stress and temperature fields of billet in cross rolling process, which can promote the precision of FEM simulation and provide scientific basis for the analysis of plug and rollers wearability. Through experiments about temperature of rollers and plug, it is evident that theoretical results well agree with experimental ones in tendency.
