| 摘 要： | 运用计算机数值模拟高压换热器钛管和管板爆炸焊接过程，并通过优化低猛度临界爆速炸药配方、选取最佳的爆炸焊接间隙、应用不稳定爆轰端控制技术等关键技术，使薄壁钛管一普通钢管板能成功实现爆炸焊接成型。此爆炸焊接成型可实现用常规焊接和胀管方法无法实现的锆、钛等稀有金属管材与钢等异形金属之间的焊接；换热器换热管与管板之间的焊接强度高，既保证了换热器的安全性，又大大提高了换热器的使用寿命；生产率高，可一次实现一台换热器所有管子与管板的焊接成型。

| Abstract: | The course of explosive welding are simulation by computer.The experiments are succeed about the plate and the thin Ti tube by optimizing critical explosive products,selecting optimum space and using instability explosion characteristic.The rare metals(such as Zr and Ti)and steel can be welded by the method of the explosive welding replacing the convention welding and expand tube.The welding strength is very high and the life is raised about of high pressure heat exchange greatly.The welding is finished in ... |
