摘要: 通过有限元软件Ansys对TP304奥氏体不锈钢管热挤压过程工模具的温度和传热进行模拟,得出X38CrMoV5-3模具钢挤压针在热挤压过程温度及热流量的分布,并计算得出生产不同规格钢管时挤压针的规格和所需水体积。Φ57.0 mm×6.3 mm~Φ139.7 mm×20.0 mm TP304不锈钢管的生产应用,结果表明,冷却工艺改进后,外径<100 mm挤压针的使用寿命由50~100次/支增加到100~150次/支,外径≥100 mm挤压针的使用寿命由100~200次/支提高到150~250次/支,显著降低成本和提高生产率。

Abstract: By finite element software Ansys the simulation on temperature and heat transfer of tool and die in hot extrusion process of TP304 austenite stainless steel tube to get the distribution of temperature and heat flux of die steel X38CrMoV5-3 extruding needle in hot extrusion process and the specification parameters and needed water volume for extruding different tube sizes are obtained by calculation. The application of production of φ57.0 mm X 6.3 mm~φ139.7 mm x 20.0 mm TP304 austenite stainless steel tubes show that with improvement o£ cooling process the service life of extruding needle with outside diameter <100 mm increases from 50~100 times/per piece to 100~150 times/per piece, and that with outside diameter ≥100 mm increases from 100~200 times/per piece to 150~200 times/per piece, the production cost decreases and the production rate increases obviously.
