Chophimba chamafuta chikatengera njira yochizira kutenthayi, imatha kupititsa patsogolo kulimba kwamphamvu, kulimba kwamphamvu, komanso magwiridwe antchito oletsa kuwononga posungira mafuta, kuwonetsetsa kuti pakugwiritsidwa ntchito bwino.Mafuta a petroleum casing ndi chitoliro chofunikira pobowola mafuta ndi gasi wachilengedwe, ndipo amafunika kugwira ntchito bwino.Kuwongolera kutentha kosiyana kumasankhidwa pazigawo zosiyanasiyana za kutentha kwa thumba la mafuta.Kutentha kumafunika kupangidwa molingana ndi kutentha kwina.Kwa 27MnCrV chitsulo, AC1 = 736℃, AC3 = 810℃, kutentha kwa kutentha kuyenera kukhala 630℃mutatha kuzimitsa, ndi kutentha kutentha Nthawi yogwira ndi mphindi 50;kutentha kwa kutentha kumasankhidwa kuchokera ku 740 mpaka 810°C panthawi ya kutentha kwapakati.Kutentha kwa kutentha kwa sub-temperature quenching ndi 780℃, ndipo nthawi yogwira ntchito yozimitsa kutentha ndi mphindi 15.Chifukwa sub-temperature kuzimitsidwa ndi mkangano muα+γ mbali ziwiri zone, quenching ikuchitika mu boma la m'deralo undissolved ferrite, kukhalabe mphamvu mkulu pamene kukwaniritsa toughness.kusintha.

Kutentha kwamafuta opangira mafuta kuyenera kuchitidwa mosamalitsa kuonetsetsa kuti chosungira mafuta opangidwa chimakhala ndi zinthu zabwino kwambiri komanso magwiridwe antchito, ndipo pokhapokha atagwiritsidwa ntchito angawonetse mtengo wabwino ndi magwiridwe antchito, amatsatira mphamvu yayikulu komanso kulimba, komanso chithandizo cha kutentha mkati. njira zosiyanasiyana.Pa nthawi yomweyo, otsika kutentha quenching kutentha ndi otsika kuposa kutentha ochiritsira, amene amachepetsa nkhawa quenching ndi kuchepetsa quenching mapindikidwe.Izi zimatsimikizira kugwira ntchito bwino kwa kupanga mafuta opangira kutentha kwa mafuta ndikupereka mikhalidwe yabwino yopangira waya wotsatira.zopangira.

Pakali pano, ndondomeko wakhala ntchito zosiyanasiyana zitsulo chitoliro processing zomera.Deta yotsimikizika yaukadaulo ikuwonetsa kuti kulimba kwa chitoliro chachitsulo chotenthetsera kutentha ndi Rm910-940MPa, mphamvu zokolola Rt0.6820-860MPa ndizoyenera 100%, komanso kulimba kwamphamvu kwa Akv65-85J kukuwonetsa kuti Chitoliro chachitsulo cha 27MnCrV chili kale. chotengera chapamwamba kwambiri chapamwamba kwambiri chamafuta amafuta.Kumbali inayi, zimasonyezanso kuti njira yozimitsa kutentha kwapansi ndi njira yabwino kwambiri yopewera kutentha kwapamwamba pakupanga zinthu zachitsulo.
