摘要/Abstract

摘要： 应用三维有限元模拟仿真技术，对Φ169 mmx6 mm T91无缝钢管8机架浮动芯棒连轧管过程，进行有限元模拟与仿真分析,获得各机架横断面等效应力分布以及轧制力、芯棒力和力距的变化特点。提岀增加前3机架轧制力,降低第4机架轧制负荷，使连轧管过程轧制力参数合理分布

Abstract: The 8- stand floating mandrel continuous rolling process of Φ169 mm x6 mm T91 steel seamless tube has been simulated and analyzed by 3- dimensional thermo-mechanical coupled FEM to get distribution of equivalent stress of across section at exit of each pass, as well as change characteristics of rolling force, mandrel force and torque. It is proposed that increasing rolling force at first 3 stands and decreasing rolling load of 4th stand lead to reasonable distribution of rolling force parameters of continuous rolling process
