随着世界性能源危机的发生,国外从七十年代起开始用氮基气氛代替各种发生炉气氛,应用于热处理上,且发展迅速。它的优点除节省能源外,还有安全、经济、来源广泛并可减少零件的氢脆等。近年来引起了国内热处理工作者的重视。氮基气氛的制取方法很多,如:用工业氮制取、纯化放热式气氛、氨燃烧、工业煤气燃烧等。我们探索了以工业氮加工业酒精制取的氮基气氛在保
With the occurrence of the global energy crisis, foreign countries began to replace the atmosphere of various furnaces with nitrogen-based atmospheres for the heat treatment and rapid development from the seventies onwards. Its advantages in addition to saving energy, but also safe, economical, wide range of sources and can reduce parts such as hydrogen embrittlement. In recent years, caused the attention of domestic heat treatment workers. Preparation of nitrogen-based atmosphere many ways, such as: industrial nitrogen system, the purification of exothermic atmosphere, ammonia combustion, industrial gas combustion. We have explored a nitrogen-based atmosphere made with industrial nitrogen processing alcohol
