Pofuna kukonza pamwamba kuuma ndi kuvala kukana wa16Mn machubu amakona anayi, mankhwala pamwamba, monga pamwamba lawi, mkulu-pafupipafupi pamwamba quenching, mankhwala kutentha mankhwala, etc. ayenera kuchitidwa machubu amakona anayi.Nthawi zambiri, malo ambiri apamwamba ndi apakatikati amazimitsidwa, ndipo kutentha kwa kutentha ndi madigiri 850-950.Chifukwa cha kusayenda bwino kwamafuta, kuthamanga kwa kutentha sikuyenera kukhala kofulumira.Apo ayi, ming'alu yosungunuka ndi ming'alu yozimitsa idzawonekera.Kuzimitsa pafupipafupi kumafuna kuti matrix okhazikika amakhala makamaka pearlite.Kuziziritsa kwamadzi opopera kapena polyvinyl alcohol solution.Kutentha kwa kutentha ndi 200-400 ℃, ndipo kuuma kwake ndi 40-50hrc, komwe kungathe kutsimikizira kuuma ndi kuvala kukana kwachubu lalikulupamwamba.
Mfundo zazikuluzikulu zotsatirazi zidzazindikiridwa pamene kuzimitsa16Mn lalikulu chubu:
(1)Chitoliro chotalikirapo sichiyenera kutenthedwa molunjika mung'anjo yosambira yamchere kapena m'ng'anjo yamoto momwe mungathere, kuti muchepetse kupindika chifukwa cha kulemera kwake.
(2)Kuwotcha mapaipi okhala ndi magawo osiyanasiyana mu ng'anjo yomweyi, mapaipi ang'onoang'ono adzayikidwa kumapeto kwa ng'anjo yakunja, ndipo mapaipi akuluakulu ndi mapaipi ang'onoang'ono adzayikidwa payokha.
(3)Ndalama iliyonse yolipiritsa idzakhala yogwirizana ndi mphamvu ya ng'anjo.Pamene kuchuluka kwa kudyetsa kuli kwakukulu, kumakhala kosavuta kukakamiza ndi kukwera kwa kutentha, ndipo nthawi yotentha imayenera kuwonjezereka.
(4)The quenching kutentha lalikulu amakona anayi machubu kuzimitsidwa ndi madzi kapena brine adzatengedwa ngati malire m'munsi, ndi quenching kutentha mafuta kapena wosungunuka mchere kuzimitsidwa adzatengedwa ngati chapamwamba malire.
(5)Panthawi yozimitsa sing'anga iwiri, nthawi yokhalamo mu sing'anga yoyamba yozimitsa iyenera kuyendetsedwa motsatira njira zitatu zomwe tafotokozazi.Nthawi yosuntha kuchokera ku sing'anga yoyamba yozimitsa mpaka yachiwiri yozimitsa sing'anga idzakhala yaifupi momwe mungathere, makamaka 0.5-2s.
(6)Mapaipi omwe pamwamba pake saloledwa kutulutsa oxidation kapena decarburization azitenthedwa mung'anjo yosambira yamchere kapena ng'anjo yoteteza.Ngati sichikukwaniritsa zikhalidwe, imatha kutenthedwa mung'anjo yolimbana ndi mpweya, koma njira zodzitetezera ziyenera kuchitidwa.
(7)Pambuyo pa chubu la 16Mn lamakona anayi litamizidwa molunjika m'njira yozimitsira, silimagwedezeka, limayenda mmwamba ndi pansi, ndikuletsa kugwedezeka kwa sing'anga yozimitsa.
(8)Pamene kuzirala mphamvu ya mbali amafuna mkulu kuuma sikokwanira, gawo lonse akhoza kumizidwa mu sing'anga quenching pa nthawi yomweyo, ndi mbali akhoza utakhazikika ndi kupopera mbewu mankhwalawa madzi bwino kuzirala liwiro.
(9)Iyenera kuyikidwa pamalo abwino otentha otentha.Kuchuluka kwa ndalama, njira yolipiritsa ndi mawonekedwe a stacking ziyenera kuonetsetsa kuti kutentha kwa kutentha kumakhala kofanana, ndipo sizingatheke kuyambitsa kupunduka ndi zolakwika zina.
(10)Kutentha mu ng'anjo yamchere, sikudzakhala pafupi kwambiri ndi electrode kuti musapewe kutentha kwapafupi.Mtunda uyenera kukhala wapamwamba kuposa 30mm.Mtunda wochokera ku khoma la ng'anjo ndi kuya kwa kumizidwa pansi pa mlingo wamadzimadzi ukhale wofanana ndi 30mm.
(11)Chitsulo chachitsulo ndi chitsulo cha carbon chikhoza kutenthedwa mwachindunji mu ng'anjo ndi kutentha kwa quenching kapena 20-30 ℃ kuposa kutentha kwa quenching.Mkulu wa carbon ndi mkulu aloyi zitsulo ayenera preheated pa pafupifupi 600 ℃ ndiyeno kukwezedwa kutentha quenching.
(12)The quenching kutentha akhoza moyenerera kuchuluka kwa mipope ndi kwambiri kuumitsa wosanjikiza, ndi kutentha m'munsi quenching akhoza kusankhidwa mipope ndi osaya kuumitsa wosanjikiza.
(13)Pamwamba pa chubu lalikulu la 16Mn pasakhale mafuta, sopo ndi zinyalala zina.Kwenikweni, kutentha kwa madzi sikuyenera kupitirira 40 ℃.
