*Bright Annealing Definition
I-Bright annealing (BA) isho ukuthi impahla yensimbi engagqwali ibaselwa esithandweni esivaliwe endaweni enciphisa igesi engasebenzi kanye ne-hydrogen evamile.Ngemva kokupholisa ngokushesha nokupholisa ngokushesha, indawo engaphandle yensimbi engagqwali inesendlalelo esivikelayo, esingenakho ukubonakaliswa endaweni yomoya ovulekile.Lesi singqimba simelana nokuhlasela okulimazayo.Ngokuvamile, ubuso bezinto ezibonakalayo bushelelezi futhi bukhanya.
* Ipayipi Lensimbi Eline-Annealed Elikhanyayo
Ipayipi lensimbi licutshungulwa ngemuva kokukhishwa okukhanyayo.Kule nqubo, ezinye izici zibaluleke kakhulu kwikhwalithi yepayipi yensimbi.Uma inqubo ye-annealing ekhanyayo ingalungile, izoholela ekuqhekekeni, okungase kugqwale.Ipayipi eliguquguqukayo ngokuvamile lisesimweni esikhanyayo se-annealed.
* Ukulungiselela ngaphambi kokukhishwa okukhanyayo
Ubuso be-tube kufanele buhlanzeke futhi bungabi nezinye izinto zangaphandle, noma yiziphi izinto ezishiywe ebusweni be-tube zizodala umonakalo ngesikhathi sokucubungula.
Ngakho-ke, ngemva kokuqonda izidingo ezinemininingwane zekhasimende, uma ikhasimende lifuna ukukhiqiza amapayipi ezimboni anenani eliphakeme, ngokuvamile sincoma ukungeza inqubo yokuhlanza ngaphambi kokufakwa okukhanyayo.Ipayipi yensimbi ihlanzwa ukungcola kanye namabala kawoyela ngamanzi ashisayo, bese yomiswa ngokushesha emoyeni emzimbeni wesithando sokushisa, futhi umphumela okhanyayo uzoba ngcono.
* Isimo sokuzivikela
I-annealing atmosphere kufanele ingabi nawo umoya-mpilo, yenze isimo se-vacuum.Igesi elivikelayo ngokuvamile i-hydrogen eyomile noma i-argon ukuze kube nomphumela okhanyayo.
* I-Annealing lokushisa
Izinga lokushisa le-annealing kufanele linqunywe ngokuya ngamazinga ahlukene ensimbi engagqwali.Ngokuvamile, izinga lokushisa lokuphefumula lensimbi ye-austenitic okungenani i-1040 degrees, futhi isikhathi sokucwiliswa asibalulekile.Amazinga okushisa aphezulu ayadingeka ukuze kubonakale ukukhanya.Shisisa ngokushesha okukhulu, ukushisa kancane kuzodala i-oxidation.
Ezinye izinsimbi ezingenasici ze-ferritic zidinga izinga lokushisa eliphansi le-anneal, njenge-TP439, engakwazi ukukhishwa ngokugqamile, futhi ukucisha kwamanzi kuzokwakha izikali ze-oxide.
Ngemuva kokukhishwa okukhanyayo, faka isinyathelo sokugcina sokulinganisa nokuqondisa, ingaphezulu leshubhu lensimbi engagqwali liveza ukubukeka okugqamile, futhi ishubhu elifakwe emanzini elikhanyayo alidingi ukucwiliswa.
* Inhloso kanye nezinzuzo ze-annealing ekhanyayo:
1) Susa ukuqina komsebenzi futhi uthole isakhiwo se-metallographic esanelisayo.
2) Thola indawo ekhanyayo, engeyona i-oxidizing futhi imelana nokugqwala.
I-3) Ukwelashwa okukhanyayo kugcina indawo egoqayo ibushelelezi, futhi indawo ekhanyayo ingatholakala ngaphandle kokwelashwa ngemuva.
Izithando zomlilo ezikhanyayo zivame ukuhlukaniswa zibe izinhlobo ezimbili.Enye iyisithando somlilo se-muffle yohlobo lwe-mesh, kanti enye iwumshini we-inthanethi weshubhu eyodwa.Ngokuvamile, isithando se-muffle sohlobo lwe-mesh singakwazi ukucubungula amapayipi ensimbi ngobuningi ngokusebenza kahle okuphezulu.Kodwa ukushiyeka kwesithando somlilo se-muffle nakho kusobala.Ngenxa yengaphakathi elikhulu lomzimba wesithando somlilo, isikhathi sokushisa sidinga ukuba side kakhulu, ngakho ukusetshenziswa kwamandla nakho kukhulu.Ngaphezu kwalokho, ngenxa yokubekwa uphawu okungalungile, izophinde isebenzise inani elikhulu legesi elivikelayo, kodwa umphumela okhanyayo awugculisi.I-The isithando somlilo se-annealing esineshubhu elilodwa eqhubekayo ayinawo amaphutha angenhla.Ngakho-ke, kuzoba yisinqumo esingcono kubakhiqizi abafuna ukukhiqiza amapayipi ensimbi anenani eliphakeme noma abafuna ukungena emakethe yamapayipi ensimbi ephezulu. I-Hangao Tech (SEKO Machinery) nayo inamamodeli amabili ahlukene ongakhetha kuwo.Uhlobo lwe-Zhijin luwonga kakhulu amandla futhi luhambisana nemvelo, futhi uhlobo lokufakwa kwe-thermal lungathola umphumela wokukhanya ongcono.
