Izinga lokushisa lokushintsha kwesigabaishidi lethusi le-tinukusuka ku-α→α+ ε cishe ku-320 ℃, okungukuthi, izinga lokushisa lokushisa lingaphezu kuka-320 ℃, isakhiwo siyisakhiwo sesigaba esisodwa, kuze kube yilapho sishiswa sibe ngu-930 ℃ noma isakhiwo sesigaba se-liquid, uma kucatshangelwa ukusetshenziswa kwemishini, izinga le-oxidation ye-workpiece ngemva kokushisa kanye nokucutshungulwa kwangempela kwe-workpiece ngemva kokwelashwa kokushisa nezinye izakhiwo.Izinga lokushisa lokushisisa liphezulu kakhulu, i-oxidation ye-workpiece ibucayi.Izinga lokushisa liphansi kakhulu, amandla okusebenza kanye nokunwebeka kuphezulu futhi ukuqina ngokusobala akwanele, akufanelekile ukubunjwa.
Ngenxa yenani elikhulu lesithando somlilo, ukuze alenze libe ne-dithermal futhi athole amandla athile nokuqina, ukuze kube lula ukucutshungulwa kokugoba okulandelayo, ucezu ngalunye lwesithando somlilo kuya ekushiseni kufanele lubambe cishe ama-2h, khona-ke lungaba nokwelashwa okubandayo olungenalutho, lungaphinde lushiye ucezu lokusebenzela emgqonyeni wokufudumeza upholisa kancane.Ngokuvamile, i-workpiece ecutshunguliwe ingabonakala ngezindlela ezimbili.Enye iwukubheka umbala we-workpiece, okungukuthi, i-workpiece ecutshunguliwe kusukela kumbala wethusi wangempela kuya kumbala ohlaza okwesibhakabhaka, ngenxa ye-oxidation nangaphezulu kwendawo yokusebenza ukukhiqiza ungqimba lwe-oxide owu-2 ~ 3μm, kulula ukuwa.
Okwesibili, i-workpiece ingacutshungulwa ngokuqondile ngokugoba ngesandla ukuze ibandlulule.Lapho ugoba, uma unomuzwa wokuthi i-workpiece inamandla athile kanye nokunwebeka, kodwa futhi ingagoba, khona-ke umphumela we-annealing muhle, ulungele ukwenza ukucubungula.Ngokuphambene nalokho, amandla nokunwebeka kwe-workpiece ngemva kokwelashwa kuphakeme, futhi akulula ukugoba ngesandla, okubonisa ukuthi umphumela wokwelapha wokukhipha i-anneal mubi, futhi udinga ukuhushulwa futhi.
Ukuze kuzuzwe inhloso yokushisa okufanayo kanye ne-oxidation, ucezu olusebenzayo lweshidi lethusi lensimbi ngokuvamile alufanele ukucutshungulwa esithandweni somlilo ngaphandle kokunyakazisa ifeni.Isibonelo, ngaphansi kwesimo sezinga elifanayo lesithando somlilo, i-workpiece iphathwa esithandweni somlilo ngaphandle kwe-fan eshukumisayo kanye nesithando somlilo nge-fan eshukumisayo ngokulandelanayo.
I-workpiece yeshidi lethusi lethayela eliphathwa ngesithando somlilo webhokisi linokukhanya okuhlukile, amandla aphezulu kanye nokuqina okwanele, okunzima ukugotshwa nokucutshungulwa.Ngemuva kokwelashwa kwesithando somlilo we-batch efanayo ye-workpiece, i-luster ifana, amandla nokuqina kufanelekile, okuhambisana nokusebenza okulandelayo kokucubungula.
