本文通过对反应塔模拟件以各种方式进行爆炸消除应力处理,采用小孔法和全释放法测量了各种工艺对模拟件环、纵焊缝以及附加焊缝的消除应力效果。制定了对化工反应塔合理的爆炸处理工艺,并对一台爆炸消除应力处理的大型反应塔采用小孔法进行了爆炸处理前后的应力测试。结果表明,对各种焊后需要消除应力的反应塔完全可以采用爆炸法进行焊后消除应力处理.此项工作为焊接结构爆炸消除应力提供了广阔的前景。 In this paper, the reaction tower simulation by a variety of ways to deal with the explosion stress relief, the use of small hole method and the full release method for measuring the simulation of various parts of the ring, longitudinal weld and additional weld stress relief effect. A reasonable explosion treatment process for the chemical reaction tower was established. The stress test before and after the explosion treatment was performed on a large reaction tower with stress-relieving and explosion-proof processing by the pinhole method. The results show that all kinds of post-welding reaction stress relieving tower can be completely eliminated by blasting method after stress relieving.This work provides a bright prospect for eliminating the stress caused by explosion in welded structure.
