Ubushushu besigaba sotshintsho lweiphepha lobhedu lenkcenkceukusuka ku-α→α+ ε malunga ne-320 ℃, oko kukuthi, ubushushu bokufudumala bungaphezulu kwe-320 ℃, isakhiwo sisakhiwo sesigaba esisodwa, de sifudunyezwe ukuya kwi-930 ℃ okanye isakhiwo sesigaba solwelo, ngokuqwalasela ukusetyenziswa kwezixhobo, iqondo le-oxidation ye-workpiece emva kokufudumeza kunye nokulungiswa kwangempela kwendawo yokusebenza emva konyango lobushushu kunye nezinye iimpawu.Ubushushu bokufudumala buphezulu kakhulu, i-oxidation yomsebenzi inzulu.Ubushushu buphantsi kakhulu, amandla okusebenza kunye nokunwebeka kuphezulu kwaye ukuqina ngokucacileyo akwanelanga, akufanelanga ukubunjwa.
Ngenxa yobuninzi beziko, ukwenzela ukuba i-dithermal kwaye ifumane amandla athile kunye nokuqina, ukwenzela ukuba kube lula ukugoba okulandelayo, i-workpiece nganye yeziko ukuya kwiqondo lokushisa kufuneka ibambe malunga ne-2h, ngoko ingaba unyango olubandayo olungenanto, inokushiya i-workpiece kwi-barrel yokupholisa ngokucothayo.Ngokubanzi, i-workpiece esetyenzisiweyo inokuchongwa ngokulula ngeendlela ezimbini.Omnye kukuqwalasela umbala we-workpiece, oko kukuthi, i-workpiece esetyenzisiweyo ukusuka kumbala wobhedu wokuqala ukuya kumbala ozuba, ngenxa ye-oxidation kunye nomphezulu we-workpiece ukuvelisa i-2 ~ 3μm engqindilili ye-oxide, kulula ukuwa.
Okwesibini, i-workpiece inokucutshungulwa ngokuthe ngqo ngokugoba ngesandla ukucalula.Xa ugoba, ukuba uvakalelwa kukuba i-workpiece inamandla athile kunye no-elasticity, kodwa iyakwazi ukugoba, ngoko umphumo we-annealing ulungile, ulungele ukwenza inkqubo.Ngokuchasene noko, ukomelela kunye nokunwebeka kwesixhobo sokusebenza emva konyango kuphezulu, kwaye akukho lula ukugoba ngesandla, nto leyo ebonisa ukuba isiphumo sonyango lwe-anneal ayilunganga, kwaye kufuneka iphinde ihlanjwe kwakhona.
Ukuze kuphunyezwe injongo yobushushu obufanayo kunye ne-oxidation, i-workpiece ye-tin ye-bronze sheet ayifanelekanga ukusetyenzwa kwibhokisi yomlilo ngaphandle kokuvuselela ifeni.Ngokomzekelo, phantsi kweemeko zesixa esifanayo sesithando somlilo, i-workpiece iphathwa kwisithando somlilo ngaphandle kokuvuselela i-fan kunye nesithando somlilo kunye ne-fan eshukumisayo ngokulandelanayo.
I-workpiece ye-tin bronze sheet ephathwa yi-box-type furnace ine-luster eyahlukileyo, amandla aphezulu kunye nokuqina okungonelanga, okunzima ukugoba kunye nokucutshungulwa.Emva kokunyangwa kwesithando somlilo we-batch efanayo ye-workpiece, i-luster ifana, amandla kunye nokuqina kufanelekile, okuhambelana nokusebenza okulandelayo.
