Inhloso ye-annealing ukwenza umqhubi ngenxa yenqubo yokuqina kwesikhunta ngenxa yezinguquko ze-lattice kanye nokuqina kocingo ngokusebenzisa ukushisa okuthile, ukuze ukuhlelwa kabusha kwe-lattice yamangqamuzana ngemva kokuthola izidingo zenqubo yokuthamba, ngesikhathi esifanayo. isikhathi sokususa i-conductor surface lubricant residual, uwoyela, njll., ngesikhathi senqubo yokuqina, ukuze ucingo lube lula ukudweba, qinisekisa ikhwalithi yocingo olunamelled.
Into ebaluleke kakhulu ukuqinisekisa ukuthi ucingo olunamelled lunobumnene obufanele kanye nokwelula ngesikhathi sokusebenzisa ukuvuthwa, ngenkathi kusiza ukuthuthukisa ukuqhutshwa kwe-conductivity.
Uma idigri ye-deformation ye-conductor iba nkulu, i-elongation iyancipha futhi iyanda amandla aqinile.
I-Copper wire annealing, evame ukusetshenziswa ngezindlela ezintathu: i-disk annealing;I-annealing eqhubekayo emshinini wokudweba ucingo;I-annealing eqhubekayo emshinini we-lacquer.Izindlela ezimbili zokuqala azikwazi ukuhlangabezana nezidingo zobuchwepheshe bokugqoka.I-disk annealing ingathambisa intambo yethusi kuphela, futhi uwoyela awuphelele, ngoba ucingo luthambile ngemva kwe-annealing, futhi ukugoba kuyanda lapho ucingo luvaliwe.
Ukudonsa okuqhubekayo emshinini wokudweba izintambo kungathambisa intambo yethusi futhi kususe amafutha angaphezulu, kodwa ngemva kokubopha, intambo yethusi ethambile ilinyazwa ku-reel yocingo ukuze yakhe ukugoba okuningi.I-annealing eqhubekayo ngaphambi kokudweba emshinini wokupenda ayikwazi nje ukufeza injongo yokuthambisa nokukhipha amafutha, kodwa futhi ucingo oluhlanganisiwe luqondile, ngqo kudivayisi yepende, lungafakwa ngefilimu yepende efanayo.
Izinga lokushisa lesithando somlilo kufanele linqunywe ngokuya ngobude besithando somlilo, imininingwane yocingo lwethusi kanye nesivinini somugqa.Ngezinga lokushisa elifanayo nesivinini, lapho isithando somlilo esibambayo siba side, yilapho i-lattice yomqhubi ibuyiselwa ngokugcwele.Uma izinga lokushisa le-annealing liphansi, izinga lokushisa lomlilo liphakeme, ukuphakama kube ngcono, kodwa isenzakalo esiphambene senzeka lapho izinga lokushisa le-annealing liphezulu kakhulu, izinga lokushisa liphezulu, ubude buba buncane, futhi ingaphezulu locingo lilahlekelwa ukucwebezela, futhi kulula ukuphuka.
Ukushisa kwesithando somlilo kuphezulu kakhulu, akuthinti nje impilo yesevisi yesithando somlilo, kodwa futhi kulula ukushisa umugqa lapho umisa futhi uqeda.Ukushisa okuphezulu kwesithando somlilo kuyadingeka ukuthi kulawulwe cishe ku-500℃.Kusebenza kahle ukukhetha amaphuzu okulawula izinga lokushisa ezindaweni ezifanayo zokushisa okumile nokuguquguqukayo.
I-Copper kulula ukuyikhipha emazingeni okushisa aphezulu, i-copper oxide ixega kakhulu, ifilimu kapende ayikwazi ukunamathela ngokuqinile ocingweni lwethusi, i-copper oxide inomphumela omuhle ekugugeni kwefilimu kapende, ekuguquguqukeni kocingo olunamele, olushisayo. ukushaqeka, ukuguga okushisayo kunemiphumela emibi.Ukuze ucingo lwethusi alukho oxidized, kuyadingeka ukwenza ucingo lwethusi ekushiseni okuphezulu ngaphandle kokuxhumana nomoya-mpilo emoyeni, ngakho-ke kufanele kube negesi elivikelayo.Izithando zomlilo eziningi zivalwe ngamanzi komunye umkhawulo futhi zivuleke komunye.
Amanzi akusinki wesithando somlilo anemisebenzi emithathu: avala isithando somlilo, apholisa ucingo, futhi akhiphe isitimu njengegesi evikelayo.Ekuqaleni kokushayela ngenxa ye-annealing tube ye-steam encane, ayikwazi ukuphuma ngesikhathi esifanele emoyeni, i-annealing tube ingagcwaliswa ngesisombululo esincane sotshwala (1: 1).(Qaphela ukuthi ungaphuzi utshwala obumsulwa futhi ulawule inani elisetshenzisiwe)
Izinga lamanzi ethangini lokudonsa amanzi libaluleke kakhulu.Ukungcola emanzini kuzokwenza ucingo lungahlanzekile futhi luthinte upende, lungakwazi ukwenza ifilimu yokupenda ebushelelezi.Okuqukethwe kwe-chlorine emanzini asetshenzisiwe kufanele kube ngaphansi kuka-5mg/l futhi ukuqhutshwa kukagesi kufanele kube ngaphansi kuka-50μΩ/cm.Ngemva kwesikhathi esithile, ama-ion e-chloride anamathiselwe ebusweni bocingo lwethusi azogqwalisa ucingo lwethusi kanye nefilimu kapende, okubangele amachashaza amnyama ebusweni bocingo efilimini kapende yocingo olungenasici.Ama-gutters kumele ahlanzwe njalo ukuze kuqinisekiswe ikhwalithi.
Kudingeka izinga lokushisa lamanzi kusinki.Izinga lokushisa eliphezulu lamanzi livumela ukwenzeka kwesitimu samanzi ukuze kuvikelwe ucingo lwe-annealing lwethusi, intambo ephuma ethangini akulula ukuletha amanzi, kodwa ekupholiseni kocingo.Nakuba izinga lokushisa eliphansi lamanzi lidlala indima yokupholisa, kunamanzi amaningi ocingweni, angahambisani nokudweba.Ngokuvamile, umugqa owugqinsi upholile futhi umugqa omncane ufudumele.Lapho ucingo lwethusi luphuma emanzini futhi lwenze ukuchaphaza, izinga lokushisa lamanzi liphezulu kakhulu.
Ngokuvamile, umugqa owugqinsi ulawulwa ku-50 ~ 60 ℃, umugqa ophakathi ulawulwa ku-60 ~ 70 ℃, futhi umugqa ocolile ulawulwa ku-70 ~ 80 ℃.Ngenxa yesivinini esikhulu kanye nenkinga enkulu yamanzi, ucingo oluncane kufanele lomiswe ngomoya oshisayo.
