爆炸消除应力是机械制造中的新工艺,对多数读者可能比较陌生,但它能够解决整体清除应力、热处理难以解决或无法解决的大型焊接结构消除应力的难题。井能提高接头的抗应力窗蚀、抗疲劳、抗脆断、抗再热裂纹的性能,因而,提高构件的安全性能。本文中介绍的爆炸消除应力,在球罐、管道接头、15m~3趴式液氨貯罐及石油化工反应塔上工业性试验结果表明,这种工艺在锅炉压力容器行业和管道工程上也有着广阔的发展前景。诚然,爆炸清除应力新工艺,目前仍处于工业性试验阶段,工艺本身尚未纳入有关规程,因而不能立即在锅炉压力容器行业中推广应用,但是,我们希望读者能从中得到一些有益的启示。 Explosion stress relief is a new process in machine construction that may be unfamiliar to most readers but it solves the stress-relieving problems of large welded structures that are totally stress-relieving, heat-treating hard to resolve or unsolvable. Wells can improve the joint stress corrosion window, anti-fatigue, brittle fracture resistance, anti-reheat crack performance, thereby improving the safety performance of components. This article describes the explosion to eliminate stress in the tank, pipe joints, 15m ~ 3 lie liquid ammonia storage tank and petrochemical reactor industrial test results show that this process in the boiler pressure vessel industry and pipeline engineering also has Broad prospects for development. It is true that the explosion of stress-relieving new technology is still in the industrial test stage, the process itself is not included in the relevant regulations and therefore can not be immediately applied in the boiler and pressure vessel industry, but we hope that readers can get some useful inspiration.
