1. Ubushushu bokufudumala, ixesha lokubamba kunye nendlela yokupholisa: Ubushushu besigaba sokutshintsha kweipleyiti yobhedu yenkcenkceukusuka ku-α→α+ε malunga ne-320 ℃, oko kukuthi, ubushushu bokufudumala bungaphezulu kwe-320 ℃, kwaye isakhiwo sayo sisakhiwo sesigaba esisodwa, de sitshiswe kwi-930 Isigaba sesigaba solwelo sibonakala sijikeleze ℃.Ukuqwalasela izixhobo ezisetyenzisiweyo, iqondo le-oxidation ye-workpiece emva kokufudumeza, kunye neyona ndlela yokucubungula intsebenzo ye-workpiece emva konyango lobushushu, emva kokuthelekisa kwisayithi kunye nokuqinisekisa, ubushushu bokufudumala kwe (350 ± 10) ℃ bufanelekile.Ubushushu bokufudumala buphezulu kakhulu, kwaye i-workpiece i-oxidized kakhulu.
Ukuba iqondo lokushisa liphantsi kakhulu, amandla kunye ne-elasticity ye-workpiece ephezulu kwaye ukuqina ngokucacileyo akwanelanga, ngoko akufanelekile ukwenza.Ngenxa yesixa esikhulu sokulayishwa kwesithando somlilo (230kg/35kW pit furnace), ukwenzela ukuba sifudumale kwaye sifumane amandla athile kunye nokuqina, ukuze kube lula ukuqhubekeka kokugoba okulandelayo, izixhobo zokusebenza kwiziko ngalinye kufuneka zigcinwe zishushu malunga neeyure ezi-2 emva kokufikelela ubushushu.Inokupholiswa ngomoya, okanye i-workpiece inokushiywa kwi-barrel yokufudumala ukuze iphole kancinci.
2. Ukuchongwa kwesiphumo sonyango lwe-annealing: Ngenxa yeemeko ezilinganiselweyo, iindlela ezimbini zingasetyenziselwa ukuchonga ngokulula i-workpiece ephathwayo.Omnye kukuqwalasela umbala we-workpiece, oko kukuthi, i-workpiece ephathwe kakuhle itshintsha ukusuka kumbala wobhedu wokuqala ukuya kumbala omnyama.Okwesibini kukuba i-workpiece esetyenzisiweyo inokugwetywa ngokuthe ngqo ngokuyigoba ngesandla.Xa ugoba, ukuba i-workpiece inokugoba ngelixa unamandla athile kunye no-elasticity, oko kuthetha ukuba umphumo wokukhupha ulungile kwaye ufanelekile ukubunjwa.Ngokuchasene noko, amandla kunye nokunwebeka kwe-workpiece emva kokunyanga kuphezulu, kwaye akulula ukugoba ngesandla, ebonisa ukuba umphumo wonyango we-annealing awulungile, kwaye kufuneka uhlaziywe kwakhona.
3. Izixhobo kunye nendlela yokulayishwa kwesithando somlilo: Ukuze kufezekiswe injongo yokufana kweqondo lokushisa kunye ne-anti-oxidation, izixhobo zokusebenza ze-tin bronze azifanelekanga ukuqhutyelwa kwiibhokisi zeebhokisi ngaphandle kokuvuselela abalandeli.Ngokomzekelo, phantsi kwemeko yomthwalo ofanayo wesithando somlilo (amandla omlilo yi-230kg / 35kW), i-workpiece iphathwa kwisithando somlilo ngaphandle kokuvuselela i-fan kunye ne-pit temping furnace kunye ne-fan evuselelayo, ngokulandelanayo.Ngaphantsi kweemeko ezifanayo zokufudumeza (350 ± 10) ℃, ukubamba i-2h kunye nokupholisa umoya, iziphumo zonyango ezimbini zahluke kakhulu.
Izixhobo zokusebenza eziphathwe ngesithando somlilo zinobuqhetseba obuhlukeneyo, amandla aphezulu kunye nokuqina okunganeleyo, okunzima ukugoba.Emva kokucubungula ibhetshi efanayo yee-workpieces kunye nesithando somlilo esivuthayo, ubuqaqawuli bufana ngakumbi, kwaye amandla kunye nokuqina kufanelekile, okuhambelana nokusebenza okulandelayo.Ke ngoko, kumashishini aneemeko ezilinganiselweyo, unyango lwe-annealing lunokucutshungulwa sisithando somlilo, kwaye umgqomo wokufudumeza nomthamo omkhulu ungasetyenziselwa ukutshaja.Izixhobo zokusebenza kufuneka zibekwe kakuhle ukuphepha ukuguqulwa kwezinto zokusebenza eziphantsi ngenxa yoxinzelelo.
