Intambo Yensimbi Engagqwali engu-316 kanye no-317
Isingeniso Kucingo Lwensimbi
Ukudweba ucingo lwensimbi engagqwali (ukudweba ucingo lwensimbi engagqwali): inqubo yokucubungula ipulasitiki yensimbi lapho kudonswa khona induku yocingo noma insimbi engenalutho emgodini wedayi wokudweba ucingo ngaphansi kwesenzo samandla okudweba ukukhiqiza ucingo lwensimbi olunezingxenye ezincane noma ucingo lwensimbi olungenalo insimbi. Izintambo ezinezimo ezahlukene kanye nosayizi bezinsimbi ezahlukene kanye nama-alloy zingakhiqizwa ngokudweba. Ucingo oludwetshiwe lunobukhulu obuqondile, indawo ebushelelezi, imishini yokudweba elula kanye nezikhunta, kanye nokukhiqizwa okulula.
Ukuboniswa Komkhiqizo
Izici Zenqubo
Isimo sokucindezeleka sokudweba ucingo yisimo sokucindezeleka esiyinhloko esinezinhlangothi ezintathu sokucindezeleka kokucindezela okunezindlela ezimbili kanye nokucindezeleka kokudonsa ngendlela eyodwa. Uma kuqhathaniswa nesimo sokucindezeleka esiyinhloko lapho zonke izinkomba ezintathu ziwukucindezeleka kokucindezela, ucingo lwensimbi oludonswe kalula lufinyelela isimo sokuguqulwa kwepulasitiki. Isimo sokuguquguquka sokudweba yisimo sokuguquguquka esiyinhloko esinezindlela ezintathu sokuguqulwa kokucindezela okunezindlela ezimbili kanye nokuguqulwa kokudonsa okukodwa. Lesi simo asisihle ekuqineni kwezinto zensimbi, futhi kulula ukukhiqiza nokudalula amaphutha obuso. Inani lokuguquguquka kokudlula enkambisweni yokudweba ucingo linqunyelwe yisici salo sokuphepha, futhi lapho inani lokuguquguquka kokudlula lincane, kulapho ukudweba kudlula khona kakhulu. Ngakho-ke, ukudlula okuningi kokudweba okuqhubekayo ngesivinini esikhulu kuvame ukusetshenziswa ekukhiqizweni kocingo.
Isigaba Somkhiqizo
Ngokuvamile, ihlukaniswe ngochungechunge olu-2, uchungechunge olu-3, uchungechunge olu-4, uchungechunge olu-5 kanye nochungechunge olu-6 lwensimbi engagqwali ngokusho kwe-austenitic, i-ferritic, insimbi engagqwali enezindlela ezimbili kanye nensimbi engagqwali ye-martensitic.
Insimbi engagqwali engu-316 kanye ne-317 (bheka ngezansi ukuze uthole izakhiwo zensimbi engagqwali engu-317) yizinsimbi ezingagqwali eziqukethe i-molybdenum. Okuqukethwe kwe-molybdenum ensimbi engagqwali engu-317 kuphakeme kancane kunokwensimbi engagqwali engu-316. Ngenxa ye-molybdenum ensimbini, ukusebenza kwayo yonke le nsimbi kungcono kunensimbi engagqwali engu-310 kanye ne-304. Ngaphansi kwezimo zokushisa okuphezulu, lapho ukuhlushwa kwe-sulfuric acid kuphansi kuno-15% nangaphezulu kuno-85%, insimbi engagqwali engu-316 inokusetshenziswa okubanzi. Insimbi engagqwali engu-316 nayo inokumelana okuhle nokugqwala kwe-chloride, ngakho-ke ivame ukusetshenziswa ezindaweni zasolwandle. Insimbi engagqwali engu-316L inokuqukethwe okuphezulu kwekhabhoni okungu-0.03, okungasetshenziswa ezisetshenziswayo lapho ukunamathisela kungenzeki khona ngemva kokushisela futhi kudingeka ukumelana okukhulu kokugqwala.
