摘　　要：应用MSC.MARC软件建立不锈钢复合板热轧成形三维热力耦合有限元模型,对不锈钢复合板热轧过程进行数值模拟,研究压下量、变形温度和初始层厚比对轧制复合变形区EH40层和316L层厚比变化规律的影响,得到了在轧制复合变形区内双金属分层变形量和层厚比变化情况的分布规律。根据数值模拟结果,建立了复合板各组元变形量与压下量的近似关系式,得到了初始层厚比计算的经验公式。通过试验与经验公式计算出的初始层厚比进行对比验证,得出层厚比误差在10%以内,有效控制了复合板层厚比精度。A three dimensional thermal mechanical coupled the finite element model was established through MSC. MARC software, and the slab hot rolling process was simulated using the current numerical model. The effects of the pass reduction, the deforming temperature and the initial thickness ratio on the thickness ratio variation of the EH40 lay er and the 316L layer in the roll bonding deformation region were investigated. Moreover, the distribution of the bimetal lic delamination thickness and the thickness ratio variation were obtained. Based on the numerical simulation results, the equation between the element deformation and the pass reduction, the equation between the element deformation and the pass reduction, and experiential formulas of the initial thickness ratio were obtained. Comparing the experiment re sult and the formula calculation result, the error was controlled within 10%, and the accuracy of the composite slab thickness ratio was effectively controlled.
