1. Izinga lokushisa lokushisa, isikhathi sokubamba kanye nendlela yokupholisa: Izinga lokushisa lokushintsha kwesigaba seipuleti lethusi lensimbiukusuka ku-α→α+ε cishe ku-320 ℃, okungukuthi, izinga lokushisa lokushisa lingaphezulu kuka-320 ℃, futhi isakhiwo saso siyisakhiwo sesigaba esisodwa, kuze kube yilapho sishiswa sibe ngu-930 Isakhiwo sesigaba se-liquid sibonakala sizungeze ℃.Uma kucatshangelwa imishini esetshenzisiwe, izinga le-oxidation ye-workpiece ngemva kokushisa, kanye nokusebenza kwangempela kokucubungula kwe-workpiece ngemva kokwelashwa kokushisa, ngemva kokuqhathanisa endaweni nokuqinisekiswa, izinga lokushisa lokushisa (350 ± 10) ℃ lifaneleka kakhulu.Izinga lokushisa lokushisisa liphezulu kakhulu, futhi i-workpiece i-oxidized kakhulu.
Uma izinga lokushisa liphansi kakhulu, amandla nokunwebeka kwe-workpiece kuphezulu futhi ukuqina ngokusobala akwanele, ngakho-ke akufanelekile ukubunjwa.Ngenxa yenani elikhulu lokulayishwa kwesithando somlilo (230kg/35kW pit furnace), ukuze sishisise futhi sithole amandla athile nokuqina, ukuze kube lula ukucutshungulwa kokugoba okulandelayo, izinto zokusebenza esithandweni ngasinye zidinga ukugcinwa zifudumele cishe amahora ama-2 ngemva kokufinyelela izinga lokushisa.Ingapholiswa ngomoya, noma i-workpiece ingashiywa emgqonyeni wokufudumeza ukuze iphole kancane.
2. Ukuhlonzwa komthelela wokwelashwa kwe-anneal: Ngenxa yezimo ezilinganiselwe, izindlela ezimbili zingasetshenziswa ukukhomba kalula ucezu lokusebenza olulashiwe.Enye iwukubheka umbala we-workpiece, okungukuthi, i-workpiece ephathwe kahle ishintsha kusukela kumbala wethusi wangempela ukuya ku-blue-black.Okwesibili ukuthi i-workpiece ecutshunguliwe ingahlulelwa ngokuqondile ngokuyigoba ngesandla.Uma ugoba, uma ucezu lokusebenza lungagotshwa ngenkathi lunamandla athile nokunwebeka, kusho ukuthi umphumela wokudonsa muhle futhi ulungele ukubunjwa.Ngokuphambene nalokho, amandla kanye nokunwebeka kwe-workpiece ngemva kokwelashwa kuphezulu, futhi akulula ukugoba ngesandla, okubonisa ukuthi umphumela wokwelapha we-anneal awumuhle, futhi udinga ukuphinda uxhunywe.
3. Indlela yokulayisha izinsiza kanye nesithando somlilo: Ukuze kuzuzwe inhloso yokufana kwezinga lokushisa kanye ne-anti-oxidation, izinto zokusebenza zensimbi yethusi ngokuvamile azifanelekile ukucutshungulwa eziko ngaphandle kokunyakazisa abalandeli.Isibonelo, ngaphansi kwesimo somthwalo ofanayo wesithando somlilo (amandla omlilo angama-230kg / 35kW), i-workpiece iphathwa esithandweni somlilo ngaphandle kwe-fan eshukumisayo kanye nesithando somlilo esishisayo esine-fan eshukumisayo, ngokulandelanayo.Ngaphansi kwezimo ezifanayo zenqubo yokushisa ku-(350 ± 10) ℃, ukubamba amahora angu-2 bese kuba ukupholisa komoya, imiphumela yokwelashwa okubili ihluke kakhulu.
Ama-workpieces aphathwa ngesithando somlilo webhokisi anobuhlakani obuhlukile, amandla aphezulu kanye nokuqina okwanele, okunzima ukugoba.Ngemuva kokucubungula iqoqo elifanayo lama-workpieces ngesithando somlilo somgodi, ukukhanya kufana kakhulu, futhi amandla nokuqina kufanelekile, okulungele ukucubungula imisebenzi elandelayo.Ngakho-ke, kumabhizinisi anezimo ezilinganiselwe, ukwelashwa kwe-anneal kungacutshungulwa yisithando somlilo, futhi umgqomo oshisayo onamandla amakhulu ungasetshenziswa ukushaja.Ama-workpieces kumele abekwe ngobunono ukuze kugwenywe ukuguquguquka kwezinto zokusebenza ezingaphansi ngenxa yengcindezi.
