摘　　要：采用三维有限元模拟分析技术,针对PQF五机架连轧和MPM七机架连轧过程进行了有限元数值模拟分析,建立的有限元模型及其边界条件合理可靠;PQF比MPM单辊轧制力有明显减少;提高PQF轧机芯棒限动速度,可以有效减少芯棒所受摩擦力,提高芯棒使用寿命。PQF and MPM continuous roiling process was simulated by three-dimensional finite element method. Finite element model had been established and boundary conditions are reasonable and reliable. Single-roll rolling force on PQF mill was significant reduction compared with 2-roll MPM＇s. It can effectively reduce friction, as inereasing the speed of retained mandrel. And it is a feasible measure to increase the speed of retained mandrel for improving the lifespan of mandrel.
