Njira yochizira kutentha kwa chitoliro chachitsulo makamaka imaphatikizapo magulu 5 awa:

1, kuzimitsa + kutentha kwakukulu (komwe kumadziwikanso kuti kuzimitsa ndi kutentha)

Chitoliro chachitsulo chimatenthedwa ndi kutentha kozimitsa, kotero kuti mawonekedwe amkati a chitoliro chachitsulo amasandulika kukhala austenite, ndiyeno atakhazikika mofulumira kuposa liwiro lofunika kwambiri lozimitsa, kotero kuti mkati mwa chitoliro chachitsulo chimasandulika kukhala martensite, ndiyeno. kupsya mtima ndi kutentha kwambiri, potsiriza, dongosolo zitsulo chitoliro ndi kusandulika yunifolomu mtima sopranite.This ndondomeko sangathe kusintha mphamvu ndi kuuma chitoliro zitsulo, komanso organically kuphatikiza mphamvu, plasticity ndi kulimba kwa chitoliro chachitsulo.

2, normalizing (yomwe imadziwikanso kuti normalizing)

Pambuyo potenthetsa chitoliro chachitsulo ku kutentha kwa kutentha, mkati mwa chitoliro chachitsulo chimasandulika kukhala austenite, ndiyeno njira yochizira kutentha imakhazikika ndi mpweya ngati sing'anga. , bainite, martensite, kapena chisakanizo cha them.This ndondomeko sangathe konza njere, yunifolomu zikuchokera, kuthetsa nkhawa, komanso kusintha kuuma chitoliro zitsulo ndi ntchito yake kudula.

Normalizing + kutentha

Chitsulo chubu ndi usavutike mtima kwa kutentha normalizing, kuti dongosolo mkati mwa chubu chitsulo kwathunthu kusandulika mu austenite dongosolo, ndiyeno utakhazikika mu mlengalenga, ndiyeno tempered. + bainite, kapena tempered bainite, kapena tempered martensite, kapena tempered sortensite. kulimba.

4 ,kubweza

Ndi njira yochizira kutentha yomwe chubu chachitsulo chimatenthedwa mpaka kutentha kwa annealing ndikusungidwa kwa nthawi inayake, kenako kuzirala mpaka kutentha kwina ndi ng'anjo.Kuchepetsa kuuma kwa chitoliro chachitsulo, kuwongolera pulasitiki yake, kuti zithandizire wotsatira. kudula kapena kuzizira mapindikidwe processing; Yenga mbewu, kuthetsa zolakwika microstructure, yunifolomu mkati kapangidwe ndi zikuchokera, kusintha ntchito ya chitsulo chitoliro kapena kukonzekera wotsatira ndondomeko; deformation kapena kusweka.

5. Chithandizo chamankhwala

Chitsulo chubu ndi mkangano kwa kutentha yankho, kuti carbides ndi zinthu alloying mokwanira ndi uniformly kusungunuka mu austenite, ndiyeno chubu chitsulo utakhazikika mwamsanga, kuti mpweya ndi alloying zinthu alibe nthawi precipitate, ndi ndondomeko kutentha mankhwala. Kapangidwe kamodzi austenite ndi discover.Function ya ndondomeko: yunifolomu mkati kapangidwe zitsulo chitoliro, yunifolomu zikuchokera zitsulo chitoliro; Chotsani kuumitsa m'kati processing kuti atsogolere kuzizira wotsatira. mapindikidwe processing; Bwezerani kukana dzimbiri zitsulo zosapanga dzimbiri.
