Zopangirazambirizachinyengopambuyokupanga, kudula, chithandizo cha kutentha ndi njira zina. Pofuna kuonetsetsa kuti faifiyo imapangidwira komanso kuchepetsa mtengo wopangira, zinthuzo ziyenera kukhala ndi malleability abwino, machinability, hardability, hardability and grindability; Iyeneranso kukhala ndi chiwopsezo chochepa cha oxidation, decarburization ndi kuzimitsa mapindikidwe ndi kusweka.
1, kusasinthika:ali ndi kutentha kochepakupangakukana mapindikidwe, plasticity wabwino, kupanga kutentha osiyanasiyana ndi lonse, kupanga mng'alu ozizira mng'alu ndi mpweya mpweya carbide chizolowezi ndi otsika.
2, ndondomeko yowonjezera:spheroidizing annealing kutentha osiyanasiyana ndi lonse, annealing kuuma ndi otsika ndi kusinthasintha osiyanasiyana ndi kochepa, spheroidizing mlingo ndi mkulu.
3, kudula makina:lalikulu kudula kuchuluka, otsika chida imfa, otsika Machining pamwamba roughness.
4, makutidwe ndi okosijeni, kukhudzidwa kwa decarburization:Kutentha kwapamwamba kwambiri, kukana kwa okosijeni kumatha kukhala kwabwino, kuthamanga kwa decarburization kumakhala pang'onopang'ono, sikumamva kutentha kwa sing'anga, kupanga chizolowezi cha pitting ndikochepa.
5, kuuma:pambuyo kuzimitsa, ali yunifolomu ndi mkulu pamwamba kuuma.
6, Kuwumitsa:pambuyo kuzimitsa, wosanjikiza wozama kwambiri angapezeke, ndi sing'anga kuzimitsira akhoza kuumitsa ndi quenching zolimbitsa.
7, kuzimitsa chizolowezi chosweka:ochiritsira kuzimitsa voliyumu kusintha ndi yaing'ono, mawonekedwe warping, kupotoza ndi pang'ono, matenda mapindikidwe chizolowezi otsika. Kuzimitsa kokhazikika kumakhala ndi chidwi chochepa chophwanyika ndipo sikukhudzidwa ndi kutentha kozimitsa ndi mawonekedwe a workpiece.
8, Kukhazikika:The akupera gudumu wachibale imfa yaing'ono, palibe kuwotcha malire akupera kuchuluka ndi lalikulu, akupera gudumu khalidwe ndi kuzirala si tcheru, zovuta kuvala kuwonongeka ndi akupera mng'alu.
