Menene Dehydrogen Annealing?

Dehydrogen annealing ne azafi magani tsariyi don cirewanarkar da hydrogendaga jabun abubuwan da aka gyara. Ana iya shigar da hydrogen a lokacin:

• Pickling (tsaftacewa acid)

• Electroplating

• Walda

• Ƙirƙira a cikin yanayi mai laushi ko hydrogen

Idan ba a cire ba, kwayoyin hydrogen na iya haifar da sufashewar hydrogen(HIC), jinkirta tsagewa, koasarar ingantattun injiniyoyi.

Tsarin cirewa ya haɗa da dumama ƙirƙira zuwa zafin jiki mai sarrafawa - ƙasa da wurin recrystallization - da kuma riƙe shi na ƙayyadadden lokaci don ba da damar hydrogen ya bazu daga cikin lattin ƙarfe.

Me yasa Dehydrogen Annealing Yana da Muhimmanci?

Tsarin yana da mahimmanci don dalilai da yawa:

• Yana hana gazawar hydrogen embrittlement

• Yana dawo da kaddarorin inji kamar ductility da tauri

• Yana inganta aminci da aminci a cikin sabis

• Mahimmanci don saduwa da sararin samaniya, motoci, da ƙa'idodin ingancin nukiliya

Don abubuwan da ke da ƙarfi kamar bolts, gears, shafts, da sassa na tsari, dehydrogen annealing yana tabbatar da aiki na dogon lokaci kuma yana rage haɗarin gazawar da ba zato ba tsammani.

sakysteelyana ba da kayan ƙirƙira tare da zaɓi na dehydrogen annealing sabis don masana'antu tare da ƙayyadaddun kayan inji da buƙatun aminci.

Kayayyakin da ke buƙatar Dehydrogen Annealing

Ana amfani da dehydrogen annealing akan abubuwa na jabu masu zuwa:

• Karfe Karfe(musamman masu rauni da fushi)

• Alloy karafa(misali, 4140, 4340, 1.6582)

• Martensitic bakin karfe(misali, 410, 420)

• Austenitic bakin karfe(misali, 304, 316 - bayan pickling ko plating)

• Titanium da titanium gami

• Alloys na tushen nickel(a cikin wuraren da aka fallasa hydrogen)

Forgings da aka fallasa don tsaftace acidic, halayen electrochemical, ko yanayin da ke ɗauke da hydrogen su ne manyan ƴan takara don wannan magani.

Tsarin Dehydrogen Annealing Tsarin Forgings

1. Pre-Tsaftacewa

Kafin a shafa, ya kamata a tsaftace ƙirƙira da mai, datti, ko yadudduka na oxide don guje wa gurɓata yayin maganin zafi.

2. Ana lodawa cikin Furnace

Ana ɗora sassan a hankali cikin tsabtataccen tanderu mai bushe tare da kyakkyawan yanayin zagayawa ko kariyar yanayi idan an buƙata.

3. Matsayin dumama

Sashin yana zafi a hankali zuwa zafin jiki na dehydrogenation. Matsalolin zafin jiki gama gari sun haɗa da:

• Ƙarfe na ƙirƙira: 200-300 ° C don ƙananan ƙarfe mai ƙarfi, 300-450 ° C don ƙarfin ƙarfe mai ƙarfi

• Titanium alloys: 500-700 ° C

• Alloys nickel: 400-650 ° C

Ana guje wa dumama cikin sauri don hana zafin zafi ko warping.

4. Lokacin Jiki

Ana yin ƙirƙira a yanayin zafin da aka yi niyya don ba da damar hydrogen ya watsa waje. Lokacin jiƙa ya dogara da:

• Nau'in kayan abu da taurin

• Kaurin bango da lissafi

• Matsayin bayyanar hydrogen

Yawancin lokacin jiƙa:
2 zuwa 24 hours.
Ƙa'idar babban yatsan hannu: awa 1 a kowace inch na kauri, ko kuma kamar yadda aka saba yi.

5. Sanyi

Ana yin sanyaya a hankali a cikin tanderu ko iska don guje wa girgizar zafi. Don aikace-aikace masu mahimmanci, ana iya amfani da sanyaya inert gas.

sakysteelyana amfani da madaidaitan zafin jiki, tanderun shirye-shirye tare da madaidaicin haɓakawa da sarrafa lokacin jiƙa don tabbatar da daidaiton sakamako na ɓarnawar dehydrogen.

Kayayyakin Amfani

• Wutar lantarki ko iskar gas

• Yanayi mai sarrafawa ko murhun wuta (na titanium / nickel gami)

• Thermocouples da masu kula da zafin jiki

• Na'urorin gano hydrogen (na zaɓi)

Na'urori masu sarrafa kansu tare da rakodin zafin jiki suna tabbatar da gano tsari.
