Hanyar hana nakasawa na tanderun lantarki na gwaji zafi magani da quenching

1. Tsananin sarrafa ingancin albarkatun kasa, da kuma kula da lahani kamar su sako-sako a cikin karfe, band-like, net-like da carbide liquefaction, da inclusions.

2. Inganta girman da rarraba carbides a cikin tsarin da aka lalata.

3. Pre-siffata da damuwa damuwa annealing kafin quenching. Ragowar nakasar juyi da ragowar damuwa na juyawa suna da tasiri mafi girma akan quenching nakasar. Don ingantattun samfuran da sikirin-bango, sassan sifofi masu rikitarwa, yakamata a sake fasalin su gaba kuma a sanya su cikin damuwa da damuwa a 450-670 ℃.

4. Ka guji yawan zafin jiki mai zafi. A cikin yanayin samun tsarin da ya dace da taurin, bai kamata a yi la’akari da shi ba don ƙara yawan haɗuwa da ƙara yawan zafin jiki na quenching. Don ingantattun sifofi na asali (kamar an daidaita su ko na biyu), yakamata a rage zafin zafin da ya dace.

5. The quenching dumama ya kamata a hankali da kuma uniform. A saboda wannan dalili, sassan ya kamata a sanya su daidai a cikin yankin isothermal a cikin tanderun, kuma ba kusa da jikin dumama ba. Ya kamata a kauce wa warping da extrusion; idan ya cancanta, za a iya preheated a 400～500 ℃ kafin dumama don kauce wa overheating da m dumama.

6. A guji yawan sanyaya. A saboda wannan dalili, ya kamata a zaɓi matsakaicin sanyaya da kyau kuma ya kamata a sarrafa zafin jiki na matsakaici. Idan ba a ƙasa da ƙimar sanyaya mai mahimmanci ba, yi ƙoƙarin rage sanyaya, musamman lokacin da ya yi ƙasa da 450 ° C, ya kamata a sanyaya a hankali. Don sassa masu sassauƙa cikin sauƙi, irin su ferrules masu bangon bakin ciki tare da manyan diamita. Za a iya zaɓar yin amfani da man quenching mai daraja ko austempering nitrate.

7. Yi ƙoƙari don sanyaya uniform. Lokacin quenching da sanyaya, wajibi ne a yi la’akari da sanyaya iri ɗaya na duk sassan ɓangaren. Yi amfani da matsewar iska ko injin motsa jiki da sauran matakan sanyaya. Lokacin zabar na’ura mai jujjuyawa, yakamata a yi amfani da saurin juyawa daban-daban gwargwadon diamita na ferrule.

8. Guji karo na inji na sassa. A guji yin karo a lokacin sufuri, lodin tanderu, dumama, da sanyaya aiki, musamman a cikin jajayen yanayin zafi. Kamar: dumama a cikin tanderun lantarki na gwaji, yi hankali da nakasar sassan lokacin amfani da kayan aiki.
