摘要
通过数值模拟的方式可以研究涡轮盘制备各个工艺环节的影响因素,实现对涡轮盘成品性能的严格控制。本文综述了涡轮盘典型制备路线:真空感应熔炼、电渣重溶、真空电弧重熔、均匀化处理、开坯、锻造和热处理7个工艺阶段的数值模拟计算方法的发展现状,归纳了各工艺阶段的模型构建方法和研究重点。阐述了目前对合金产品制备过程集成模拟的研究进展,并介绍了本课题组进行的涡轮盘制备全流程数值模拟工作。最后分析了多工艺集成化模拟的难点,为未来涡轮盘制备过程的全流程集成模拟提供借鉴。
The influencing factors in various stages of the turbine disk manufacture have been considered by numerical simulation to tightly control performance of finished turbine disk.This paper reviewed the developing status of numerical simulation method of superalloy turbine disks manufacturing way,including seven process stages of vacuum induction melting(VIM),electroslag remelting(ESR),vacuum arc remelting(VAR),homogenization treatment,cogging,forging and heat treatment,and summarized the modeling methods and research focus of each stages.Then the research progress of integrated modeling of superalloy products manufacture were introduced,and our simulation research for the whole manufacture process of turbine disk was illustrated.Finally,the difficulties of multi-process integrated modeling were analyzed,which may provide references for the whole process integrated simulation of turbine disks manufacture in the future.
