2the redox reaction of atmosphere and Fe, N
2with the neutral protective atmosphere that other rare gas elementes are steel, wherein N
2application at most, but must remove oxygen atmosphere wherein, can play a good protection, generally conventional N
2with H
2hybrid protection atmosphere.
During the annealing of metal current material surface brighting, mostly adopt a kind of cooling gas---liquefied ammonia.Liquefied ammonia can produce the hydrogen of 75% ~ 80% and the nitrogen of 20% ~ 25% after pyrolytic decomposition.Ammonia combustion atmosphere is a kind of controllable atmosphere of nitrogen; can be used for the surface-brightening annealing of the material such as ferrous alloy, copper base alloy; normalizing; quenching; tempering; the multiple heat treated protective atmosphere such as soldering and timeliness, can be used as again reduction and the sintering atmosphere of powder metallurgy, makes metal can keep the original luminance brightness of metal material surface after Overheating Treatment.Liquefied ammonia and ammonia are poisonous, inflammable gases, CAS:7664-41-7, and belong to one of hazardous chemical of national safety supervision department emphasis supervision, applying unit must special messenger be taken appointment with certificate, and will form major hazard source as storage capacity exceedes critical amount; During use misoperation or occur leakage can cause personnel poisoning, blast and environmental pollution; Constituents hydrogen out also belongs to flammable explosive gas, as operation or improper use, also very easily produces blast, causes great personnel and property damage; Need during constituents to consume a large amount of energy, busbar bright annealing technology cost is remained high.
