35CrMo钢气瓶在热处理时发生爆裂,对其样件进行宏观检验、微观分析、力学性能测试、化学成分分析,并对同批次气瓶进行现场模拟试验以及有限元分析。结果表明:密封气瓶内壁粘附的石墨和水在高温下生成的可燃气体与氧气反应发生爆炸,产生瞬时高压,导致气瓶爆裂。

A 35CrMo steel gas cylinder bursted during heat treatment. The macroscopic inspection, micro analysis, mechanical test and chemical composition analysis of the sample were carried out, as well as site simulation and finite element analysis. The results show that the combustible gas, generated from the combination of graphite adhering to the inner wall of sealing cylinder and water at high temperature, reacting with oxygen cause explosion, producing instantaneous high pressure, and then causing the gas cylinde to burst. © 201...
