Ndi zotani njira zochizira kutentha

1. Njira yopangira Annealing: Mukatenthetsa chitsulo ku Ac3 + 30 ~ 50 madigiri kapena Ac1+30 ~ 50 madigiri kapena kutentha pansi pa Ac1 (zambiri zoyenera zitha kufunsidwa), nthawi zambiri muziziziritsa pang’onopang’ono ndi kutentha kwa ng’anjo.

2. Njira yoyendetsera ntchito mwachizolowezi: tenthetsani chitsulo mpaka madigiri 30 ~ 50 pamwamba pa Ac3 kapena Accm, ndipo muziziziritsa pamlingo wokwera pang’ono wozizira kuposa kutsekera pambuyo posunga kutentha.

3. Njira yozimitsa ntchito: tenthetsani chitsulo pamwamba pa kutentha kwa Ac3 kapena Ac1, chisungeni kwa kanthawi, ndiyeno muzizizizira msanga m’madzi, nitrate, mafuta, kapena mpweya. Cholinga: Kuzimitsa nthawi zambiri kumakhala kupeza mawonekedwe olimba kwambiri a martensitic. Nthawi zina, pozimitsa zitsulo zamtengo wapatali (monga zitsulo zosapanga dzimbiri ndi chitsulo chosavala), ndiko kupeza mawonekedwe amodzi ndi ofananirako austenite kuti athetse kukana kuvala. ndi kukana dzimbiri.

4. Njira yogwiritsira ntchito kutentha: Yatsaninso chitsulo chozimitsidwa ku kutentha kwina pansi pa Ac1, ndikuziziritsa mu mpweya kapena mafuta, madzi otentha kapena madzi mutatha kusunga kutentha.

5. Njira yoyendetsera ntchito yozimitsa ndi kutentha: kutentha kwapamwamba pambuyo pozimitsa kumatchedwa kuzimitsa ndi kutentha, ndiko kuti, kutentha kwachitsulo ku kutentha kwa madigiri 10 ~ 20 kuposa kuzimitsa, kuzimitsa pambuyo posungira kutentha, ndiyeno kutenthetsa pa kutentha kwa madigiri 400-720. XNUMX ~ XNUMX madigiri.

6. Njira yogwiritsira ntchito ukalamba: kutentha chitsulo ku madigiri 80 ~ 200, sungani kutentha kwa maola 5 ~ 20 kapena kuposerapo, ndiyeno mutulutse mu ng’anjo ndikuziziritsa mumlengalenga. Cholinga: 1. Kukhazikika kwa chitsulo pambuyo pozimitsa, kuchepetsa kusinthika panthawi yosungirako kapena kugwiritsa ntchito; 2. Chepetsani kupsinjika kwamkati mutatha kuzimitsa ndikupera, ndikukhazikitsani mawonekedwe ndi kukula kwake.

7. Njira yogwiritsira ntchito mankhwala ozizira: Kuziziritsa zitsulo zozimitsidwa m’malo otsika otentha (monga ayezi wouma, madzi a nayitrogeni) mpaka -60 mpaka -80 madigiri kapena kutsika, ndiyeno mutenge kutentha kwa yunifolomu kutentha.

8. Njira yogwiritsira ntchito kutentha kwa moto kuzimitsa: moto woyaka ndi mpweya wosakanikirana wa oxygen-acetylene umapopera pamwamba pa gawo lachitsulo, ndipo umatenthedwa mofulumira. Kutentha kozimitsa kukafika, kuziziritsidwa ndi kupopera madzi nthawi yomweyo.

9. Njira yopangira kutentha kwapamwamba yozimitsa ntchito: ikani gawo lachitsulo mu inductor kuti mupange mphamvu yowonongeka pamwamba pa gawo lachitsulo, mutenthetse kutentha kwa kutentha mu nthawi yochepa kwambiri, ndiyeno perekani madzi kuti azizizira.

10. Njira yogwiritsira ntchito carburizing: Ikani chitsulo m’kati mwa carburizing, kutentha mpaka madigiri 900-950 ndikutentha, kotero kuti pamwamba pa chitsulo chikhoza kupeza chosanjikiza cha carburized ndi ndende ndi kuya kwake.

11. Njira yogwiritsira ntchito nitriding: gwiritsani ntchito maatomu a nayitrogeni omwe amawola ndi mpweya wa ammonia pa madigiri 500 mpaka 600 kuti pamwamba pa gawo lachitsulo likhale lodzaza ndi nayitrogeni kuti apange wosanjikiza wa nitrided.

12. Njira yopangira nitrocarburizing: carburizing ndi nitriding panthawi imodzi pamwamba pazitsulo. Cholinga: Kupititsa patsogolo kuuma, kuvala kukana, mphamvu ya kutopa ndi kukana kwa dzimbiri pazitsulo.
