摘要
本文主要对非焊接储氢瓶式容器热处理工艺—双面淬火进行了研究,通过对淬火机构的设计,淬火介质的分析、选择,及热处理工艺的调整,对该工艺制造的50MPa瓶式站用储氢容器产品进行空气中强度、侧膨胀量、冲击吸收能量、硬度和氢气中慢应变速率拉伸数据分析,测得在氢气中和在空气中的抗拉强度之比、最大总延伸率之比分别为99.5%和98.2%,满足《加氢站储氢压力容器专项技术要求》T/CATSI 05003-2020中在氢气和空气中的抗拉强度之比、最大总延伸率之比均不小于0.9的要求。
This paper mainly studies the heat treatment process of the non welded hydrogen storage bottle container double-sided quenching. Through the design of the quenching mechanism, the analysis and selection of the quenching medium, and the adjustment of the heat treatment process, the strength in air, measured expansion, impact absorption energy, hardness, etc. of the 50MPa bottle type station hydrogen storage container manufactured by this process are analyzed, The ratio of tensile strength in hydrogen and in air and the ratio of maximum total elongation are 99.5% and 98.2% respectively, which meet the requirements that the ratio of tensile strength in hydrogen and air and the ratio of maximum total elongation are not less than 0.9 in the special technical requirements for hydrogen storage pressure vessels in hydrogen stations(T/catsi 05003-2020).
