Forgingsngokuvamileumgunyathingemvaukuqamba, ukusika, ukwelashwa kokushisa nezinye izinqubo. Ukuze kuqinisekiswe ikhwalithi yokukhiqiza ye-die futhi yehlise izindleko zokukhiqiza, impahla kufanele ibe nokusebenziseka okuhle, ukusebenziseka kalula, ukuqina, ukuqina kanye nokugaya; Kufanele futhi ibe nokuthambekela okuncane kwe-oxidation, i-decarburization kanye nokucisha i-deformation kanye nokuqhekeka.
1, ukonakala:inokushisa okuphansiukuqambaukumelana ne-deformation, i-plasticity enhle, ububanzi bokushisa bokubumba bubanzi, ukukhwabanisa okubandayo okubandayo kanye nokuthambekela kwe-carbide yenethiwekhi kuphansi.
2, inqubo yokufaka:ububanzi bezinga lokushisa le-spheroidizing annealing libanzi, ubulukhuni be-annealing buphansi futhi uhla lokuguquguquka luncane, izinga le-spheroidizing liphezulu.
3, ukusika imishini:inani elikhulu lokusika, ukulahleka kwethuluzi eliphansi, ubulukhuni obusezingeni eliphansi bomshini.
4, i-oxidation, ukuzwela kwe-decarburization:ukushisa okuphezulu kokushisa, ukumelana ne-oxidation kungaba kuhle, ijubane le-decarburization lihamba kancane, alizwani nendawo yokushisa, ukukhiqizwa kokuthambekela kwe-pitting kuncane.
5, ukuqina:ngemva kokucisha, inokuqina okufanayo kanye nobulukhuni obuphezulu.
6, Ukuqina:ngemva kokucisha, ungqimba oluqinile olujulile lungatholakala, futhi i-medium quenching ingaba lukhuni ngokucisha okuphakathi.
7, ukucima ukuthambekela kokuqhekeka kwe-deformation:ukuguqulwa kwevolumu evamile kuncane, ukungqubuzana komumo, ukuhlanekezela kuncane, ukuthambekela kokuguquguquka okungavamile kuphansi. Ukucisha okuvamile kunokuzwela okudabukisayo okuphansi futhi akuzwakali ekucimeni izinga lokushisa nokuma kocezu lomsebenzi.
8, Ukugaya:isondo lokugaya ukulahlekelwa isihlobo kuncane, akukho umkhawulo wokushiswa inani lokugaya likhulu, ikhwalithi yesondo lokugaya kanye nezimo zokupholisa azibucayi, akulula ukugqoka umonakalo nokugaya i-crack.
