摘要/Abstract

摘要： 基于有限元模拟仿真方法,对真空气淬热处理炉热区的温度场和流体场进行精细模拟,并模拟出空载、只装载料框和装载叶片的3种不同实际生产过程中可能遇到的情况的温度场和流体场。通过采用9点测温的方法,监测出有效加热区的温度变化趋势。同时,对不同部位的流速场进行监测。并结合实测数据,总结出温度变化规律以及温度场-流速场之间的耦合关系。为总结出热区温度-流速变化规律与分布状况,以及未来实现真空热处理的精密调控打下基础。

Abstract: Based on finite element simulation method, the temperature and fluid fields of the vacuum heat treatment furnace hot zone were simulated precisely. The temperature and fluid fields involving three different actual product situations which are empty loading, only loading frame and full loading blade were simulated. The temperature tendency in qualified working zone is monitored by nine points temperature testing method. Meanwhile, the fluid field at several different parts were monitored. Compared to the measuring data, the variation of the temperature and the coupling relationship between furnace temperature and its fluid field were summarized. The foundation was laid to summarize the temperature-velocity interaction and distribution pattern and achieve the precisely controlling of the vacuum heating treatment in the future.

Key words: superalloy, heat treatment, vacuum gas quenching furnace, finite element simulation
