摘　　要：用有限元软件对某公司共轭延伸孔型系统轧制进行了模拟。在模拟分析之后得出了孔型系统易产生镰刀弯、轧出方坯对称性不好等问题。针对这些问题进行了孔型调整优化。对调整优化后的孔型模拟验证,结果表明,调整后的孔型系统可用于实际生产。The hot rolling of the conjugate pass system was simulated by a iron and steel company with finite element software. After analyzing the simulation results, that the pass system was able to cause such problems as camber and asymmetric billet. Aiming at these problems, the conjugate pass system was adjusted. The hot rolling of the new pass system was simulated. And the simulation results show that the new pass system can be applied to practical production.
