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.
